2-Stage Relay Module




The IOR-2 is intended for use with BMS controllers to convert an analogue control output to a raise/lower, high/low or binary relay output pair.

Applications include the control of raise/lower valve and damper actuators , and pump changeover, LEDs indicate correct operation and Hand/Off/Auto jumpers ease commissioning. Low current draw from 0-10Vdc controller output means that the IOR-2 can work successfully with most BEMS controllers.
