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. |
