TM2 Expansion Modules

Overview

You can expand the number of I/Os of your M251 Logic Controller by adding TM2 I/O expansion modules.

The following types of electronic modules are supported:

oTM2 digital I/O expansion modules

oTM2 analog I/O expansion modules

For more information, refer to the following documents:

oTM2 Digital I/O Expansion Modules Hardware Guide

oTM2 Analog I/O Expansion Modules Hardware Guide

NOTE: TM2 modules can only be used in the local configuration, and only if there is no TM3 transmitter and receiver modules present in the configuration.

NOTE: It is prohibited to mount a TM2 module before any TM3 module. The TM2 modules must be mounted and configured at the end of the local configuration.
