Install the XM-124 Standard Dynamic Measurement Module Chapter 1
Module Components Operation of the XM-124 standard dynamic measurement module requires
the XM-940 Dynamic Measurement Module Terminal Base Unit (not
included).
Figure 1 - XM-124 Module Components
• XM-940 Dynamic Measurement Module Terminal Base - A DIN rail-
mounted base unit that provides terminations for all field wiring that is
required by XM vibration modules, including the XM-124 module.
• XM-124 Standard Dynamic Measurement Modules - The modules
mount on the XM-940 terminal base via a keyswitch and a 96-pin
connector. The modules contain the measurement electronics,
processors, relay, and serial interface port for local configuration.

IMPORTANT XM-124 module certifications are valid only when used with the
1440-TB-A/C revision of the terminal base.
IMPORTANT The XM-441Relay Expansion module can be connected to the XM-124
module via the XM-940 terminal base. When connected to the module,
the Expansion Relay module simply ‘expands’ the capability of the XM-
124 module by adding four additional epoxy-sealed relays. The module
controls the Expansion Relay module by extending to it the same logic
and functional controls as the onboard relay.
