The IOR13 is intended for use with BMS controllers to convert an analogue control output to a binary, heat/cool, staged or sequenced relay modes. LED s indicate correct operation and Hand/Off/Auto jumpers ease commissioning. Low current draw from 0-10Vdc controller output means that the IOR13 can work successfully with most BEMS controllers.
• Fault finding LED indication
• Relay status LED indication
·On/Off/Auto links for ease of commissioning
• DIN Rail mounting
• Link selectable binary, heat/cool, staged or sequenced
