Output Expansion Unit - 4-Way (2019)

20-34

The new (2019) 20-34 is a low cost relay output module which enables four relays to be remotely controlled using the Salcom relay control protocol. The module provides a fully scaleable relay expansion solution for the 12-84 Relay Output Paging Receiver as modules can be "daisy chained" to control any number of relays.

Coming Soon:

The 20-34 is a low cost scalable relay output solution. Each 20-34 can allow four 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.

A green and red LED display operational status, a chart displaying status codes can be found in section 4 - Connections. A 12-terminal connector is used to bring all connections from the four relays out. The relays are not mains rated.

Programming software is not required for this product. 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. The 12-84 can be configured to send all relay control packets down the serial port to all other units.

  • Four relays
  • Units can be "daisy chained" to control any number of relays
  • 12-volt operation
  • Individually programmable outputs
  • No special software required-program
  • Configurable parameters using a terminal program
  • Can be used to switch relays under computer control
  • Ideal for remote switching applications - lights, pumps etc.
  • Reverse polarity protected
  • Optional relay restoration on power-up
  • LED indication of operational status
  • Rugged extruded aluminium case
