SDC/Security Door Controls 484O2U SGL DPDT Push to Open Plate

Overview

The SDC 484O2U is a single-gang, dual-pole dual-throw (DPDT) push-to-open controller plate designed for direct-drive access control installations. It functions as a central controller node supporting multi-credential authentication across 63 doors with capacity for up to 250,000 users. Built for integrators requiring straightforward, scalable door control without external relay modules.

Technical Specifications

Supports OSDP and TCP/IP communication protocols for seamless integration with enterprise access control systems. Credential compatibility includes DESFire, MIFARE, NFC (13.56MHz), and 125kHz Proximity formats. DPDT relay configuration permits standard fail-secure and fail-safe strike wiring strategies.

Compatibility

Suitable for retrofit and new-build deployments requiring mid-scale facility control. Compatible with multi-credential reader ecosystems and IP-networked security platforms. Recommended for installations where dedicated plate-form controllers eliminate the need for external relay interfaces.
