Schneider Electric TM3AM6 Mixed Analog I/O Module – Product Description

Overview

The Schneider Electric TM3AM6 module extends Modicon M221, M241, M251, and M262 systems with reliable mixed analog I/O. It offers four analog inputs and two analog outputs that support both current and voltage signals, allowing engineers to handle measurement and actuation within one compact module. Moreover, its stable 12-bit resolution helps maintain accurate control in fast-moving automation environments. The TM3 expansion bus ensures simple installation, therefore reducing engineering time and panel complexity.

FAQ

Q1: Which PLCs are supported?
It works with Modicon M221, M241, M251, and M262 controllers via the TM3 bus.

Q2: Can I mix voltage and current modes on different channels?
Yes. Each channel may be configured independently inside the software.

Q3: Are the outputs protected against overloads?
The module supports standard industrial loads as long as they remain within the listed ranges.

Q4: What software is used to configure the TM3AM6?
Configuration is performed through EcoStruxure Machine Expert or Machine Expert – Basic.

Q5: Does the module require external power for analog outputs?
No. The TM3 bus supplies power for the module logic, while load devices still use their own supply
