SDC 400RC433 1-Channel Wireless Receiver Controller
Overview
The SDC 400RC433 is a single-channel wireless receiver controller designed for distributed access control architectures where centralized management is infeasible or undesirable. It manages up to 63 doors and 250,000 user credentials, making it suitable for mid-scale facility integrations, multi-tenant buildings, or campus environments where you need localized credential and event processing without routing all reader traffic back to a central panel. The 400RC433 operates over OSDP and TCP/IP, bridging legacy proximity reader deployments with modern networked systems.
Compatibility
Integrates into OSDP-compliant access control ecosystems and standard IT infrastructure via TCP/IP backbone. Compatible with multiple credential technologies: DESFire, MIFARE, NFC at 13.56 MHz, and 125 kHz proximity cards — meaning you can standardize readers across facilities without credential format conflicts. Works within networked multi-door systems that require centralized event logging and credential synchronization; ideal for security integrators deploying mesh or distributed topologies where a single monolithic control panel creates a single point of failure or a bottleneck during peak traffic periods.
Installation Notes
Wireless operation reduces installation labor compared to hardwired reader runs, but verify RF range and signal propagation through walls, metal studs, and dense building materials in your target space before final placement. TCP/IP connectivity depends on a stable LAN backbone — ensure your network switch(es) serving the receiver have adequate bandwidth for concurrent reader transactions and event streaming. Multi-credential support requires reader firmware that matches the credential type being provisioned; confirm reader compatibility with your chosen card format during procurement.
