12-34-0000 Relay Output Expansion Module

Do you need to expand the number of relay outputs on your Salcom 12-84 Relay Output Paging Receiver or control relays via the serial port from your PC?  The 12-34 may be the solution you have been looking for!

The 12-34 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 scalable relay expansion solution for the 12-84 Relay Output Paging Receiver as modules can be "daisy-chained" to control any number of relays.

While it is most commonly used to expand the number of relay outputs available on the Salcom 12-84 Relay Output Paging Receiver, it has the potential to be utilised with other paging receivers and can also be used autonomously under computer control. 

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.

Programming software is not required for this product, all configurable parameters can be programmed via the serial port using a terminal program on a PC.

On startup the firmware version number, monoshot timer settings and unit ID are displayed, and can be changed.

The 12-34 is housed in a durable extruded aluminium case, but should be protected from the weather if installed outdoors.
