Channels

Relay

Overview

Relay channels can open or close a contact for a higher voltage circuit using a lower level control voltage. The Relay output channels work as a physical on/off switch, and are used to drive higher voltage devices with a lower controlling voltage.

You can configure the following Relay output channel options:

zYou can choose to manually activate/deactivate the Relay output.

zYou can choose to manually activate/deactivate the Relay output and then specify that the Relay output will either pulse (you get to specify the active and inactive pulse times) continuously or for a specified number of pulse counts.

zYou can choose to manually activate/deactivate the Relay output and then specify a delay before the output goes from inactive to active or active to inactive.

zYou can also specify a failsafe action that can either active or inactivate the Relay output when the failsafe timer is triggered (see Failsafe Timer Functionality on page 239 for more information).

In an industrial freezer warehouse, the IOLAN A4R2 is used to monitor humidity transducers, which are used 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, causing the Relay channel to activate an internal freezer dehumidifier. The Relay channel is deactivated when the Analog channel sends a clear syslog message to the Monitoring Application and the Relay channel is deactivated.
