The Current Output Module (COM) converts the data from the Wireless Receiver into a linear 4-20 mA signal for the DDC controller. The COM is loop powered and receives data from a 418 or 900 MHz Receiver through a RS485 four-wire bus. Up to 32 different Output Modules can be connected to a single receiver to send multiple network variables to the controller. The COM is easily trained to a single transmitter variable with a pushbutton and LED. The COM is surface, 2.75” snaptrack or 35mm din rail mountable.  NOTE: Item is discontinued - 3 still in stock.
