The IO-RM3 is intended for use with BMS controllers to convert an analogue control output to a binary, heat/cool, 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 IO-RM2 can work successfully with most BEMS controllers. Features: Link selectable modes binary, heat/cool, staged or sequenced  On/Off/Auto links for ease of commissioning  DIN Rail mounting Benefits: Fault finding LED indication  Relay status LED indication Input signal 0-10Vdc 1mA min. into 22kΩ impedance Output contacts 8A at 230Vac (resistive load) Power supply: 24Vac ±15% @ 50Hz or 24Vdc +15% -6%, 65mA max.
