(COMMON)
These are the second of the pair of connections made for an external device. These
terminals are for connecting the wire that leads to COMMON terminal of the external
device when connecting either a Normally Open or Normally Closed device.
A Relay Output terminal has two options for connecting a device:
•
Option 1
is for a Normally Closed configuration.
•
Option 2
is for a Normally Open configuration.
Output supports optoisolated signal for up to two connected external device relays, such as an
electrical door lock relay.
Signals can be sent as continuous (intermittent) or single pulse.
