Pulse Width Modulation Input, 4 Relay Output, Input or Output Expander / Multiplexer
Availability: In stock
The DMUX is a selectable output controller designed to expand the output capacity of an energy management or process controller. The DMUX has up to eight output relays which can be individually addressed by a single pulse width modulated input signal. Common (C), Normally Open (NO), and Normally Closed (NC) connections are available for each output. Three position On/Off/Auto jumpers are standard and allow manual override at the DMUX. The DMUX converts a relay, transistor or Triac input signal to operate an appropriate relay output based on the duration of the signal. Each relay output of the DMUX can be individually addressed by the controlling microprocessor. Each relay output has an LED indicator for a visual verification of operation. There are also LED indicators to show the presence of power to the DMUX and the input pulse. DMUX is DIP switch selectable for the following modes all DIP switch selectable: Sequence 4 or 8 relays, One of 4 or 8 relays, Individual Relay Control (4 or 8 relays), or Rooftop unit control (4 or 8 relays).
