Four Stage Relay Module




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