10 Introduction
XM-440 Module
Components The XM-440 consists of a terminal base unit and an instrument module. The
XM-440 Master Relay Module and the XM-942 Master Relay Terminal Base
are shown below.
Figure 1.1 XM-440 Module Components
• XM-942 Master Relay Terminal Base Unit - A DIN rail mounted base
unit that provides terminations for all field wiring required by the
XM-440.
• XM-440 Master Relay Module - Mounts on the XM-942 terminal base
unit via a keyswitch and a 96-pin connector. The XM-440 contains the
processor, four on-board relays, and serial interface port for local
configuration.
Using this Manual This manual introduces you to the XM-440 Master Relay module. It is
intended for anyone who installs, configures, or uses the XM-440 Master Relay
module.

IMPORTANT
Up to two XM-441 Expansion Relay modules may be
connected to the XM-440 module via the terminal base
unit.
When connected to the XM-440, the Expansion Relay
modules simply “expand” the capability of the XM-440 by
providing an additional four to eight relays. The XM-440
controls the Expansion Relay modules by extending to
them the same logic and functional controls as the XM-440
module’s on-board relays.
