TM3AQ2 Schneider Modicon TM3 Analog Output Module 2 Channel

TM3AQ2 Schneider Electric Modicon TM3 Analog Output Module

The TM3AQ2 is a 2-channel analog output module from the Schneider Electric Modicon TM3 series. Each channel configures in software for 0-10 Vdc, ±10 Vdc, 0-20 mA, or 4-20 mA. It delivers 12-bit resolution and ±0.1% full-scale accuracy at 25 °C. The module fits Modicon M221, M241, M251, and M262 controllers. It uses a removable screw terminal block with 5.08 mm pitch. This module suits valve control, drive speed reference, and analog signal retransmission in compact machines. Oiltech Controls supplies tested units with a 12-month warranty and 24-28 hour dispatch.

FAQ

Q: Can I mix voltage and current outputs on the two channels?

A: Yes. Each channel configures independently in software. You can set channel 1 to 0-10 Vdc and channel 2 to 4-20 mA. This helps when one machine uses a valve and a drive together. Confirm your controller firmware supports per-channel settings. Always wire each channel to the correct load type.

Q: How do I choose between 0-20 mA and 4-20 mA?

A: Use 4-20 mA for long cable runs and noisy plants. The live zero helps detect broken wires. Use 0-20 mA only when the actuator requires it. Most process valves and drives accept 4-20 mA. Check the input card or actuator datasheet before wiring. Set the same range in the controller software.

Q: What causes output drift over temperature?

A: The module holds ±0.1% full scale at 25 °C. Over the full temperature range, accuracy moves to ±1% full scale. Install the module in a stable cabinet area. Avoid mounting next to drives or power supplies. Allow air flow around the module. Recalibrate the process loop if drift affects quality.

Q: Which controller should I pair with the TM3AQ2?

A: Use Modicon M221 for small machines with basic analog needs. Choose M241 when you need Ethernet and more I/O. Select M251 for distributed architectures. Pick M262 for motion and high-speed processing. All four platforms accept TM3 expansion modules. Match the controller to your cycle time and network needs.

Q: How fast does the output respond after a command change?

A: Conversion takes 1 ms. Each channel adds 1 ms. The controller cycle time also adds delay. Stabilization takes 1 ms. Total response depends on your scan time. For fast loops, use a short controller cycle. For valve control, this speed is normally sufficient.
