Relay Parameters

The Relay parameters control the operation of the on-board relays, as well as
the relays on the Expansion Relay (XM-441) module(s). Use these parameters
to configure which alarms the relays are associated with as well as the behavior
of the relay.

IMPORTANT

A relay can be defined, regardless of whether or not it is
physically present. A non-physical relay is a virtual relay.
When a relay (physical or virtual) activates, the module
sends a Change of State (COS) message to its master,
which acts on the condition as necessary. An XM-440
Master Relay Module can activate its own relays in response
to a relay (physical or virtual) activation at any of its slaves.

Description

Options/Comments

Number (XM Serial Configuration
Utility only)

Sets the relay to be configured in XM Serial
Configuration Utility.

Relay Numbers 1 through 4 are the
on-board relays. Relay Numbers 5
through 12 are either relays on the
Expansion Relay modules when they
are connected to the XM-440 or virtual
relays. Up to two Expansion Relay
modules may be connected to the
XM-440.

Virtual relays are non-physical relays.
Use them when you want the effect of
the relay (monitor alarms, activation
delay, and change status) but do not
need an actual contact closure. For
example, a PLC or controller
monitoring the relay status.

Note: The Relay Installed parameter
indicates whether a relay is a virtual
relay or a physical relay on a module.

Name (XM Serial Configuration
Utility only)

A descriptive name to help identify the relay in the
XM Serial Configuration Utility.
