Install the XM-124 Standard Dynamic Measurement Module Chapter 1
Connect the Relay
The XM-124 module has Normally Open relay contacts, which close when the
control output is energized.
The alarms that are 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.
See Relay Parameters on page 86 for more information about association of an
alarm with a relay.
Table 3 shows the onboard relay connections for the modules.
IMPORTANT 24V DC must 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. See the installation instructions for your specific XM module
for complete wiring information.
TIP The Expansion Relay module can be connected to the module to provide
additional relays. For wiring details see the XM-441 Expansion Relay
Module User Manual, publication
GMSI10-UM019 .
IMPORTANT The NO terminal descriptions correspond to a de-energized (unpowered)
relay.
When the relay is configured for non-failsafe operation, the relay is
normally de-energized.
When the relay is configured for failsafe operation, the relay is normally
energized, and the behavior of the NO terminals is inverted.
