Installing the XM-320 Position Module 23
Connecting the Relays
The XM-320 has both Normally Open (NO) and Normally Closed (NC) relay
contacts. Normally Open relay contacts close when the control output is
energized. Normally Closed relay contacts open when the control output is
energized.
The alarms associated with the relay and whether the relay is normally
de-energized (non-failsafe) or normally energized (failsafe) depends on the
configuration of the module. Refer to Relay Parameters on page 58 for details.
Table 2.1 shows the on-board relay connections for the XM-320.
IMPORTANT
A Class 2 circuit can be provided by use of an NEC Class 2
rated power supply, or by using a SELV or PELV rated
power supply with a 5 Amp current limiting fuse installed
before the XM module(s).
IMPORTANT
24Vdc needs to be wired to terminal 44 (+24 V In) to
provide power to the device and other XM modules linked
to the wired terminal base via the side connector.
ATTENTION
The power connections are different for different XM
modules. Refer to the installation instructions for your
specific XM module for complete wiring information.
IMPORTANT
All XM relays are double pole. This means that each relay
has two contacts in which each contact operates
independently but identically. The following information
and illustrations show wiring solutions for both contacts;
although, in many applications it may be necessary to wire
only one contact.
TIP
The Expansion Relay module may be connected to the
XM-320 to provide additional relays. Refer to the XM-441
Expansion Relay Module User Guide for wiring details.
