IOL Pin Signal Description
Line contactor coil connections with an auxiliary contact from the control
IOL-8 COIL_E2 power circuit breaker wired in series with the contactor coil. The line
IOL-7 COIL_E1 contactor is a safety contactor that includes three main contacts with three
auxiliary contacts (see the figure on
IOL-12 ALRM_COM Non-voltage contact (ALRM_M) to indicate that CB1 is closed (make) when
CB1 is tripped. (DC)
Non-voltage contact (ALRM_B) to indicate that CB1 is closed (make) when
CB1 is not tripped.

Power supply capable of supplying 24V @ 20 A for I/O functions and
IOL-6
switches. Each set of pins is capable of 8 A. To use the full rating of the
supply, all pins must be used to provide the appropriate current rating (see
