Chapter 1 Install the XM-124 Standard Dynamic Measurement Module
Connecting Power
Power supplied to the module must be nominally 24V DC (±10%) and must be a
Class 2 rated source.
Wire the DC-input power supply to the terminal base unit as shown in
Figure 10 .

Connect the Relay
The XM-124 module has Normally Open relay contacts, which close 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 82 for details.

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 A current
limiting fuse installed before the XM module.
IMPORTANT 24V DC needs to be wired to terminal 44 (+24V 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.
