Schneider TM3AQ2 Analog Output Module 2-Channel

Product Introduction

The TM3AQ2 extends Schneider Electric's Modicon TM3 family with two analog output channels. This module delivers precise control signals to valves, drives, and positioners. Engineers choose it when compact PLC systems require accurate current or voltage outputs. The unit supports 0–10 Vdc, ±10 Vdc, 0–20 mA, and 4–20 mA signals. Each channel configures independently through software.

Technical Specifications

Specifically, the TM3AQ2 provides 12-bit resolution across all output ranges. Accuracy reaches ±0.1% of full scale at 25 °C. Temperature drift stays within ±1% of full scale across the operating range. Conversion takes 1 ms plus 1 ms per channel plus one controller cycle. Output stabilization requires 1 ms. Isolation delivers 1500 V AC between output and supply, plus 500 V AC between output and internal logic. Diagnostics cover module status and bus status. The removable screw terminal block uses 5.08 mm pitch.

Mechanical and Environmental Parameters

Furthermore, the TM3AQ2 measures 90 × 23.6 × 70 mm (H×W×D). It weighs 0.115 kg. Operating temperature ranges from 0 to +55 °C. Storage temperature spans −25 to +70 °C. Protection rating is IP20. The module mounts on standard DIN rail (TH35-15 or TH35-7.5). A green PWR LED confirms bus power.

Installation Guide

First, mount the TM3AQ2 onto a DIN rail. Next, connect the expansion bus to the controller. Then, wire output signals using twisted-pair shielded cable. After wiring, configure each channel via EcoStruxure Machine Expert software. Finally, verify the PWR LED illuminates green. The module draws 35 mA at 5 V DC with no load and 40 mA at 5 V DC under full load. At 24 V DC, consumption reaches 30 mA with no load and 70 mA under full load. Use a stable 24 Vdc supply through the TM3 bus.
