IO-RM Relay Interface

This range of relay modules is intended for use with BMS controllers to convert an analog control output into various relay switching modes. Example applications include controlling rising/falling valves, damper actuators, pump switching, and boiler control. LEDs indicate correct operation, and Hand/Off/Auto jumpers facilitate commissioning. The low current draw from the 0-10Vdc controller output ensures the IO-RM range works with most BEMS controllers.

Fault-finding LED indication
Relay status LED indication
Switching modes selectable by link
On/Off/Auto links for easy commissioning
