The S7-I/O device provides the capability to monitor and control

power system elements that are not specifically designed for

ACCESS. Remote monitoring of any device equipped with an

auxiliary contact is possible. Inputs such as the temperature relay

of a motor or transformer can be input into the I/O device. Status

of any circuit breaker with auxiliary contacts can also be

monitored. This is especially useful to monitor MCCB status

when metering functionality is not required.

The outputs can be used to close contactors, trip circuit breakers,

and provide remote indication. In combination with a power

meter analog values such as current and voltage can be

monitored.

Status of the input and output states, counter data, and event log

data is communicated to other components of the ACCESS

system through an RS-485 serial link.
