Relay Output Expansion Module

12-34-0000 Relay Output Expansion Module

This low cost relay output module enables four relays to be remotely controlled using the CST relay control protocol. The module provides a fully scalable relay expansion solution for the 12-84 Relay Output Paging Receiver as modules can be "daisy chained" to control any number of relays. Although most commonly used in conjunction with CST’s 12-84 Relay Output Paging Receiver, it has the potential to be utilised with other paging receivers and also can be used autonomously under computer control.

Features and Benefits 

  • Individually programmable outputs
  • No special software required program configurable
  • Parameters using a terminal program
  • Can be used to switch relays under computer control
  • Reverse polarity protected
  • Optional relay restoration on power-up
  • LED indication of operational status
  • Rugged extruded aluminum case
