Linear 293 Stand-Alone Access Control Relay Board, 1-Amp Form Relays, for 212i and 212w Keypads

Bring dependable relay switching to your access control installations with the Linear 293 stand-alone access control relay board. This relay module is engineered as a low-cost, professional solution for integrators who need to expand 212i and 212w keypad capabilities—converting factory transistor outputs into isolated dry contacts so locks, alarms and monitoring equipment work together seamlessly. The board includes three 1-A Form C relays and a dedicated REX input via screw terminals, giving you independent control of strikes, maglocks or auxiliary devices while maintaining reliable signaling for security and surveillance systems. Because the module plugs directly into the keypad harness, installation is fast and reduces field labor; it also addresses the keypad’s limited 50 mA output by providing full relay switching when required. Ideal for commercial and multi-tenant buildings, the Linear 293 improves interoperability with access control panels and surveillance monitoring setups. Add this relay board to your next project to simplify wiring, increase compatibility, and enhance system reliability—order now for quick integration into your security deployments.
