Overview
Analog channels monitor current/voltage input. Note that the internal jumpers must match the
software setting (by default, they are set to Current); see
Analog Input Module to find out how to set
the internal jumpers.
For example, in an industrial freezer warehouse, the IOLAN A4R2 is used to monitor humidity
transducers, which are in place to help prevent freezer burn. If the humidity reaches a certain
percentage (monitored by an Analog channel) a syslog message is sent to the Monitoring Application.
The Monitoring Application then sends a command to the IOLAN via the Perle API that causes the
Relay channel to activate an internal freezer dehumidifier. The relay is turned off when the Analog
channel sends a clear syslog message to the Monitoring Application and the Relay channel is
deactivated.
