The IOR12 converts an analogue output of an BMS controller to two stages of relay output, and acts as an interface between the controller and heating, cooling and ventilating equipment. It may be configured as a high/low or a raise/lower relay module by link selection. The raise/lower mode has a stroke time function, which is implemented by a 16-bits microcontroller. There are manual override links for each relay to aid commissioning. Field wiring is facilitated by rising cage clamp type terminals, and a supply loop terminal aids wiring to additional modules.
