ABB Bailey IIMTM01 Termination Module

The ABB Bailey IIMTM01 provides secure termination points for field device signals. This module connects directly to Bailey analog and digital input modules. It weighs approximately 0.65 kg and mounts on a standard DIN rail. Its dimensions measure 25.4 cm in length, 12.7 cm in width, and 3.2 cm in height.

Technical Specifications & Hardware Details

The IIMTM01 features twenty-four screw-type termination points for field wiring. A single 50-pin ribbon cable header links this module to the host I/O module. This unit stores no energy internally because it contains no batteries or capacitors. Four main components form the complete assembly: the PCB, the terminal block, the mounting base, and the cable connector.

Field Wiring and Signal Routing

You can connect field sensors directly to the IIMTM01 without additional adapters. Each termination point accepts either solid or stranded copper wire. For reliable signal transmission, use shielded cables for analog signals. The ribbon cable carries all twenty-four signals directly to the host I/O module.

Installation and Maintenance Requirements

This module operates reliably from -20°C to 70°C without any external power supply. Furthermore, it withstands 5g vibration across a 10 to 55 Hz frequency range. Consequently, the IIMTM01 requires zero scheduled maintenance beyond routine visual checks. Simply verify terminal screw tightness during plant shutdowns.
