PGM EXPANDER

PGM expander - consists of 4 connected modules, each of which has a relay with 2 switching output contacts - NO1 and NC1, NO2 and NC2 with a maximum current of 2A.

Two independent circuits can be connected to each module for control using the relay's separate output switching contacts.

The entire group can be powered from a single source on the +12V and GND (-12V) terminals of any of the 4 modules, at which point the green LEDs of the connected modules light up.

When a signal is sent from the PGM output to the IN input of the included module – the red LED of the corresponding module lights up.

The PGM expander can be used as interconnected 4, 3, 2 modules or a single standalone module.

Fastening the PGM expander is done with the help of the attached KEYSTONE 8803 type mounting elements (or other suitable elements) in a convenient place in the box.
