Each 12-34 can allow 4 relays to be controlled using the Salcom relay control protocol. The 12-34 can be daisy chained to allow any number of relays to be controlled.  This relay output module is ideally suited for use with the Salcom paging receivers but can also be controlled by any PC with a serial port for any general control application.

A 12 terminal connector is used to bring all connections from the 4 relays out.  Programming software is not required for this product (configured using any terminal application). On startup the firmware version number, monoshot timer settings and unit ID are displayed, and can be changed.  The relay unit connects directly to a 12-84 receiver or PC serial port without any special configuration requirements making installation painless.
