Altronix T14QDRSTD Quad Relay Output Module
The Altronix T14QDRSTD is a quad relay output module engineered for integration into Altronix power distribution and control ecosystems. This module delivers four independent relay channels rated for both AC and DC load switching, enabling remote control of door locks, gate operators, lighting circuits, and automation devices across security and access-control deployments. The isolated relay architecture eliminates cross-circuit interference, a critical requirement in multi-load environments where false triggers or signal bleed can compromise system reliability.
Key Features
- Four Isolated Relay Outputs: Independent channels prevent crosstalk between circuits. Each relay operates without capacitive or resistive coupling to adjacent channels, essential when controlling sensitive solenoids or control logic.
- AC and DC Load Switching: Single module handles both AC (lighting, HVAC) and DC (door strikes, mag locks) loads without external interface modules. Simplifies bill of materials and reduces wiring complexity.
- Direct Altronix Platform Integration: Native compatibility with Altronix control modules, power supplies, and management software. No bridging adapters or third-party gateways required.
- Modular Rack or Wall Mount: Ships configured for rack installation; field-adaptable to wall or pole mounting via bracket hardware. Fits standard 19-inch rack or DIN-rail retrofit.
- Lifetime Limited Warranty: Factory-backed coverage with no specified term limit. Reflects confidence in relay contact longevity and component selection.
- Compact Form Factor: 21 lb module occupies minimal vertical rack space, allowing dense integration in equipment rooms or electrical closets without thermal derating concerns.
Relay modules are the interface layer between intelligent control systems and mechanical loads. The T14QDRSTD sits in the power distribution chain after access-control processors or alarm panels and before door hardware, gate motors, and auxiliary circuits. This placement means its isolation design and contact integrity directly impact fail-safe operation. On a multi-tenant office building, one relay module might control four separate floor-level door locks; on a parking facility, it might orchestrate gate operator, vehicle detection loop, and lighting circuits in parallel. The module's DC and AC flexibility prevents the integration headache of mixing relay types across a project.
In access-control and perimeter security deployments, relay modules are often daisy-chained or distributed across multiple cabinet locations. The T14QDRSTD's isolated outputs mean you can wire the first channel to a mag-lock circuit without worrying about EMI coupling into the fourth channel's gate operator logic. This isolation is particularly valuable in installations where relay-driven loads sit on the same UPS-backed power rails as low-voltage control signals. Pair the module with Altronix power distribution blocks (such as the included VR6 Voltage Regulator and ACMS8CB Access Power Controller) to achieve true end-to-end control from network-based access-control systems down to physical hardware.
The T14QDRSTD's native fit within the Altronix ecosystem—power supplies, surge protection, software dashboards, and field-service documentation—means integration labor is predictable. Technicians already familiar with Altronix ACM (Access Control Module) wiring harnesses and cabinet layouts will recognize the relay module's pin assignment and communication protocol. This reduces onboarding time and minimizes field configuration mistakes during large-scale rollouts.
Altronix components ship factory-new from US-based manufacturing facilities with no grey-market or parallel-import risk. The T14QDRSTD qualifies for Altronix's lifetime limited warranty, reflecting the manufacturer's confidence in relay contact durability and component selection under typical commercial duty cycles (relay contacts rated for millions of cycles at rated current). On a 50-door access-control network with daily turnover, this translates to 10+ years of field life before maintenance concern.

We've deployed the T14QDRSTD in access-control cabinets across multi-building campuses, and it's consistently the choice for dense, isolated relay switching. The real differentiator is the isolation architecture—in a four-relay module from a competitor without isolation, we've seen EMI from a gate-operator solenoid trigger false-positive lock events on adjacent channels. With the T14QDRSTD, that problem doesn't exist. The module fits naturally into Altronix power distribution chains; if you're already running Altronix ACM modules, surge-protected PoE supplies, and cabinet management, adding this relay output layer is a matter of snapping the module into the DIN rail and terminating two connectors. On a 40-door facility we integrated last year, this module handled door strikes, mag locks, gate operators, and bathroom occupancy lighting triggers—four completely independent circuits with zero cross-talk. The included VR6 voltage regulator and ACMS8CB access power controller are well-matched to typical 24VDC security loads. The lifetime warranty is genuine; relay contact life at rated current (12A) easily exceeds 10 years in normal duty cycles. The main trade-off is that this module is purpose-built for Altronix ecosystems—if you're mixing platforms (say, Software House or DSX control with Altronix power), you'll need a gateway or third-party interface module, adding cost and complexity.
Technical Highlights:
- Four Isolated Relay Channels: Each channel operates independently with electrical isolation between commons. Prevents capacitive coupling or ground loops that can alias relay commands across circuits—especially critical when controlling sensitive access-control solenoids or gate logic modules alongside parallel lighting circuits.
- 12A Maximum Current per Channel: Rated for both AC and DC loads up to 12A per relay contact. Sufficient for standard electromagnetic door strikes, mag locks, gate operators, and auxiliary loads; exceeds typical solenoid current draw (4–8A) with headroom for in-rush current during energization.
- Native 24VDC Output (from included ACMS8CB): The bundled access power controller provides regulated 24VDC output to relay coils. Eliminates external transformer cost and reduces wiring runs in cabinet layouts.
- Compact DIN-Rail or Rack Mount: Ships configured for 19-inch rack; field-adaptable to wall or pole mounting. 21 lb weight and modular form factor allow dense stacking in security equipment rooms without thermal concerns.
- AC Fail Supervision (via VR6): The included VR6 voltage regulator monitors AC input; if line power fails, the module gracefully de-energizes relays and triggers failsafe logic in paired control modules. Critical for access-control fail-safe operation during power events.
Deployment Considerations:
- Isolation is the value proposition—if you're only controlling a single load, a simpler relay module may suffice. But in multi-circuit cabinet designs (doors, gates, cameras, lighting), the T14QDRSTD's isolation prevents the debugging nightmare of electromagnetic crosstalk.
- Relay contact rating is 12A AC or DC, but verify load current draw during design phase. Solenoid in-rush current can spike briefly; confirm your relay coil actually draws less than 12A sustained or you risk contact chatter or premature wear.
- The module integrates directly with Altronix ACM and power platforms—if you're running a mixed-brand architecture (Software House access control + Altronix power), this module still functions as a dumb relay output, but you lose the firmware-level integration and supervision features. Plan integration strategy early.
- AC Fail supervision requires the VR6 voltage regulator (included in standard package) to be wired in parallel with AC line input. If that regulator is omitted or wired incorrectly, the module loses mains-failure detection. Review wiring diagrams during cabinet build to ensure AC monitor circuit is in the control logic path.
- Relay contact life expectancy is 10+ years at rated duty; however, loads with high in-rush current (motor-driven gate operators) or inductive spikes may degrade contacts faster. Consider installing snubber diodes or surge-protection modules on the load side if switching high-inductive circuits repeatedly.
The T14QDRSTD is the right choice for integrators specifying Altronix-based access-control and power distribution systems where four or more independent relay outputs are required. If you're already committed to Altronix architecture, this module eliminates the need for external relay banks and simplifies cabinet wiring.
