Description

The IOR4 is intended for use with BMS controllers to convert an analogue control output to a binary, staged, or sequenced relay mode. LEDs indicate correct operation, and Hand/Off/Auto jumpers ease commissioning. Low current draw from the 0-10Vdc controller output means that the IOR4 can work successfully with most BEMS controllers.
