SDC 602RF 1 AMP DC Power Controller
Overview
The SDC 602RF is a 1 AMP DC power controller purpose-built for access control system deployments where you need reliable, standards-based power delivery and reader integration in a compact form factor. Operating at 24VDC, the 602RF supplies controlled power to proximity card readers, keypad readers, and devices supporting NFC/13.56MHz credential technology. Built on the Open Supervised Device Protocol (OSDP) standard, it ensures interoperability across certified readers and access control panels — a significant advantage if you're standardizing your infrastructure on protocol-driven architectures rather than proprietary wiring schemes.
Key Features
- 1 AMP 24VDC Output: Delivers sufficient current for single-door reader installations without requiring a separate power distribution module. The 1 AMP ceiling means you won't overload a reader or cause voltage sag across multiple devices on the same circuit — plan accordingly if adding auxiliary equipment like magnetic locks or request-to-exit buttons.
- OSDP Protocol Support: OSDP is the industry standard for reader-to-panel communication, replacing older Wiegand in many new deployments. Choosing an OSDP-based controller future-proofs your investment and simplifies integration with next-generation access panels and reader ecosystems.
- NFC and 13.56MHz Credential Support: Accepts modern NFC-based credentials alongside traditional proximity cards, giving you flexibility to support mobile wallet authentication or card-based systems without controller replacement. Useful in retrofit scenarios where you need to bridge legacy proximity infrastructure and emerging mobile credential adoption.
- Proximity and Keypad Reader Compatibility: The 602RF works with both proximity card readers and keypad entry devices, supporting deployments that require multi-factor workflows (card + PIN) or single-factor fallback options. No separate controllers needed for mixed reader types on the same door.
- Wired Connectivity: All communication and power delivery is hardwired — no wireless dependencies, no RF interference concerns, no battery management overhead. Simplifies troubleshooting and eliminates the latency variables you'd encounter with wireless protocols in noisy electrical environments.
- Single- and Multi-Door Deployment Ready: The 602RF is designed for single-door installations but can be chained or networked with other controllers in multi-door access control architectures. OSDP supports daisy-chain topologies, reducing panel-to-reader wiring runs in larger deployments.
Integration and Compatibility
The 602RF integrates into any access control system that supports OSDP readers and panels. If your existing infrastructure uses Wiegand-only readers, you'll need to upgrade those readers to OSDP variants — this is a real cost factor in retrofit projects, so inventory your current reader base before committing to this controller. The 24VDC requirement means you need a compatible power supply capable of delivering the necessary current; most modern access control panels include 24VDC auxiliary outputs, but verify your panel's power budget before assuming you can daisy-chain multiple controllers.
The 602RF is suitable for both new-build access control system deployments and retrofit scenarios where you're replacing older Wiegand-based controllers. Its compact wired footprint makes it ideal for wall-mounted or raceway-installed access control architectures where you're consolidating reader power and logic into a single standardized unit.
Frequently Asked Questions
Q: Can the SDC 602RF power a magnetic lock directly?
A: The 602RF outputs 1 AMP at 24VDC. Most electromagnetic locks draw 0.5–0.8 AMP, so a single lock is feasible, but you'll have limited headroom for additional devices like request-to-exit buttons or door sensors on the same circuit. For multi-device door control, consider a dedicated lock power supply and use the 602RF strictly for reader power.
Q: Is the 602RF compatible with my existing Wiegand readers?
A: No. The 602RF uses OSDP protocol, which is a different signaling standard than Wiegand. Your readers must be OSDP-certified devices. If you have legacy Wiegand readers, you'll need to replace them or use a separate Wiegand-to-OSDP converter.
Q: Can I install multiple 602RF controllers on a single 24VDC power supply?
A: Yes, if your power supply can source sufficient current. Each 602RF draws up to 1 AMP, so a 4 AMP supply can theoretically support four controllers. However, verify voltage regulation — daisy-chaining controllers increases wire resistance, which can cause voltage sag. Use a dedicated supply with appropriate current rating and keep wire runs short.
Q: Does the 602RF support two-way communication with the access panel?
A: Yes. OSDP is a bidirectional protocol, so the 602RF can report reader status, credential validation results, and fault conditions back to the panel. This enables real-time monitoring and event logging — valuable for audit trails and troubleshooting door access issues.
Q: What credentials can the 602RF handle?
A: The 602RF supports NFC and 13.56MHz credentials (like HID iClass or Mifare cards), as well as traditional proximity cards and keypad PIN entry. Your readers must support the credential type you want to deploy — the controller itself doesn't restrict credential format, but reader hardware does.
Q: Is the 602RF NDAA-compliant or subject to supply-chain restrictions?
A: No NDAA certification information is available in the product documentation. If your deployment requires NDAA Section 889 compliance, contact the manufacturer or your specialty reseller for certification details.

The SDC 602RF is a straightforward OSDP power controller that solves a specific integration problem: you need standardized, protocol-compliant reader power delivery without proprietary wiring or vendor lock-in. The 1 AMP 24VDC output is the right capacity for single-door reader installations, and OSDP support means you're building on an industry-standard foundation rather than Wiegand's aging architecture.
Technical Highlights:
- 1 AMP 24VDC Output: Sufficient for a proximity or NFC reader plus a lightweight auxiliary device (PIR sensor, door position switch), but not for direct magnetic lock control. Plan your power budget carefully — this is a reader controller, not a lock controller.
- OSDP Protocol: Bidirectional communication with the access panel means real-time status reporting, event logging, and credential validation feedback. Eliminates the one-way dump-and-pray mentality of older Wiegand setups.
- NFC/13.56MHz Support: Bridges legacy proximity card deployments and emerging mobile credential ecosystems. No controller replacement needed when you're ready to add NFC readers to a mixed credential environment.
Deployment Considerations:
- OSDP reader requirement is non-negotiable — if you have Wiegand readers, you're looking at a retrofit cost. Budget accordingly and audit your installed base before specifying the 602RF.
- The 1 AMP ceiling is real. Don't assume you can power a magnetic lock, door buzzer, and two auxiliary devices on this controller. Wire a separate lock supply and use the 602RF strictly for reader power delivery.
Deploy the 602RF in new-build access control systems where you're standardizing on OSDP from the ground up, or in single-door retrofit projects where you're replacing Wiegand infrastructure with protocol-driven architecture. Not a universal controller — it's purpose-specific, and that's exactly its strength.
