Middle Atlantic Rlnk PR USB Cont Closure - RLNK-CONT

Middle Atlantic RLNK-CONT Premium Plus Dry Contact Closure Sensor

The Middle Atlantic RLNK-CONT is a dry contact closure sensor designed for use with Middle Atlantic's RLNK Premium Plus intelligent power distribution units. It adds external trigger capability to your Middle Atlantic power management infrastructure, enabling connected devices or facility systems to signal the PDU directly — useful in AV, security, and IT rack environments where automated power responses to physical events are required. The RLNK-CONT ships at 1 lb and is TAA-compliant, making it eligible for US government and federally funded projects subject to Trade Agreements Act procurement requirements.

Overview

Dry contact closure inputs are a foundational building block in facility automation: a door sensor, motion detector, relay output from an access control panel, or environmental monitor can trigger a discrete logic signal without carrying voltage — keeping control circuits isolated from the devices they manage. The RLNK-CONT bridges that signal into the Middle Atlantic intelligent PDU ecosystem, letting rack power management respond to real-world events rather than requiring manual intervention or a separate automation controller.

For integrators building out managed rack systems in command centers, security operations, or enterprise IT rooms, pairing a network-managed PDU with dry contact inputs like the RLNK-CONT reduces the need for additional relay modules or third-party automation hardware. The signal path stays inside the rack infrastructure you're already managing.

Key Features

• TAA Compliance: The RLNK-CONT carries TAA-compliant status — a hard procurement requirement for US federal agencies, GSA schedule buyers, and many state and local government contracts. If your project has TAA language in the SOW, this box is checked.
• Dry Contact Interface: Dry contact closure inputs pass no voltage across the control circuit, which means the triggering device (door contact, PIR, relay) is electrically isolated from the PDU. This eliminates ground loop risk and simplifies wiring in mixed-voltage rack environments.
• Lightweight Form Factor: At 1 lb shipping weight, the RLNK-CONT adds negligible mass to the rack — relevant when working within weight-rated wall mounts or shallow enclosures where every pound of rack gear counts.
• Targeted Integration: Designed specifically for the RLNK Premium Plus PDU line, the RLNK-CONT slots into an existing Middle Atlantic rack accessory ecosystem rather than requiring custom wiring adapters or protocol translation.

Integration & Compatibility

The RLNK-CONT is engineered for the Middle Atlantic RLNK Premium Plus intelligent PDU family. Confirm compatibility with your specific RLNK PDU model before ordering — the contact sensor interface varies across the RLNK product line and not all variants accept external closure inputs. Consult the PDU's technical documentation to verify the closure input port and trigger logic before wiring.

Typical deployment pairings include access control relay outputs, environmental sensor dry contacts (temperature/humidity threshold alerts), and manual momentary switches for localized power control — all common in security rack and operations center builds.

Frequently Asked Questions

Q: Is the RLNK-CONT TAA compliant?

A: Yes. The RLNK-CONT is TAA-compliant, making it eligible for US federal, GSA schedule, and other government procurement programs that require Trade Agreements Act compliance.

Q: What PDUs is the RLNK-CONT compatible with?

A: The RLNK-CONT is designed for use with Middle Atlantic RLNK Premium Plus intelligent power distribution units. Verify compatibility with your specific RLNK model before ordering, as closure input support varies across the product line.

Q: What is a dry contact closure and why does it matter?

A: A dry contact closure is a switch-based signal that carries no voltage — it simply opens or closes a circuit. This provides electrical isolation between the triggering device and the PDU, reducing risk of ground loops or voltage interference in mixed-signal rack environments.

Q: How much does the RLNK-CONT weigh?

A: The RLNK-CONT has a shipping weight of 1 lb (0.5 kg).

Q: Can the RLNK-CONT be used with third-party PDUs or power strips?

A: No. The RLNK-CONT is purpose-built for the Middle Atlantic RLNK Premium Plus PDU line and is not designed as a universal dry contact adapter for third-party power distribution equipment.

Jerry Tildsen

The RLNK-CONT is a straightforward add-on, but it's worth being precise about what it does and doesn't do. It extends the Middle Atlantic RLNK Premium Plus PDU with an external dry contact input — meaning an outside signal source (door contact, relay, sensor) can trigger a power-related action at the PDU level. That's a useful capability in managed rack deployments, and the TAA-compliant designation means it clears the procurement gate for government and institutional projects without a waiver process.

Technical Highlights:

• TAA Compliance: Confirmed TAA-compliant status means this unit is procurable under GSA schedules and federal contracts without additional country-of-origin waivers — a practical time-saver on government-bid projects.
• Dry Contact Design: The voltage-free contact closure keeps the triggering device electrically isolated from the PDU's control circuit, which matters when integrating with access control panels or environmental monitors that share grounding with other building systems.
• 1 lb Form Factor: At 1 lb shipping weight, this is a compact add-on that won't impact rack load calculations — worth noting in weight-sensitive wall-mount or shallow-enclosure installs.

Deployment Considerations:

• Confirm your specific RLNK PDU model supports the closure input port before ordering — not all RLNK variants accept the RLNK-CONT, and the Middle Atlantic product line has several tiers with different feature sets.
• Available technical specifications for the RLNK-CONT are limited in public documentation; for detailed wiring diagrams and trigger logic, reference the RLNK Premium Plus PDU installation guide directly from Middle Atlantic.

Best fit for security operations centers, government IT rooms, and enterprise AV-over-IP racks where access control or environmental sensor outputs need to drive automated PDU responses — and where TAA compliance is a non-negotiable line item in the procurement spec.
