Linear 293 0-219000 is a Relay Expansion Board from Linear. Plug-on three-relay board converting transistor outputs to dry contact Form C relays for 212i and 212W keypads. Operating voltage: 12-24 VAC, 12-24 VDC. Contact configuration: 3 x Form C SPDT relays rated 1A each; REX input via screw terminals.
A: The 293 relay board is compatible with the Linear 212i (0-211111) and 212W (0-211222) keypads.
A: It provides three Form C SPDT relays each rated 1A.
A: It converts the transistor/negative-voltage outputs of the 212i and 212W to dry contact closures suitable for most access control and gate operator inputs.
A: Each energized relay adds approximately 30mA to the keypad's total current draw.
A: The 293 operates at the system voltage supplied to the host keypad, 12-24V AC/DC.
