Product Overview
This connection module provides the interface between ET 200M I/O modules and the field wiring. It accommodates up to 16 digital or 8 analog signal channels per unit. The module measures 40 mm in width, 125 mm in height, and 120 mm in depth. Its compact design weighs approximately 150 grams for efficient cabinet mounting. You can install this module on a standard DIN rail without specialized tools. The front panel features a removable screw-type terminal block for straightforward wiring.
The module supports wire sizes from 0.14 mm² to 2.5 mm² for flexible cabling options. It provides strain relief for all connected field cables to prevent accidental disconnection. The device includes a labeling strip for clear channel identification. You can replace the module without disconnecting the field wiring. Its green housing distinguishes it from other ET 200M components.

Key Features and Benefits
This module simplifies field wiring termination for ET 200M systems. Its removable terminal block allows you to pre-wire the cabinet before module installation. The strain relief prevents accidental cable pull-out during maintenance. You can label each channel clearly using the integrated strip. The module’s green color provides instant visual identification in the rack.
Installation and Wiring
You clip the module onto the DIN rail next to the ET 200M I/O module. Connect the field cables to the screw terminals on the front panel. Tighten each screw to the specified torque of 0.5 Nm. Insert the terminal block into the module housing until it locks. You can route cables through the integrated strain relief mechanism. For replacement, remove the terminal block and pull the module from the rail.
Typical Applications
Process plants use this module for terminating field instruments to ET 200M racks. Manufacturing facilities rely on it for connecting sensors and actuators. The module also serves in water treatment and building automation systems.
