This range of relay modules is intended for use with BMS controllers to convert an analogue control output to various switching relay modes. Example applications include the control of raise/lower valves, damper actuators, pump changeover and boiler control. LEDs indicate correct operation and Hand/Off/Auto jumpers ease commissioning. Low current draw from 0-10Vdc controller output means that the IO-RM range works successfully with most BEMS controllers.
