Schneider TM3AQ2G Analog Output Module 2 Channels

Buy TM3AQ2G | Modicon TM3 2-Channel Analog Output Module

Product Introduction

The TM3AQ2G analog output module expands the Modicon TM3 controller family with two high-performance analog channels. Schneider Electric engineered this module to generate both voltage and current signals, covering standard industrial ranges including -10 to 10 V, 0 to 10 V, 0 to 20 mA, and 4 to 20 mA. Therefore, it serves as an ideal solution for driving actuators, valves, positioners, and other analog-controlled devices in your automation system.

This output module stands out due to its exceptional precision and speed. The TM3AQ2G offers 11-bit plus sign resolution for voltage outputs and 12-bit resolution for current outputs. Additionally, the stabilization time reaches only 1 ms, ensuring rapid response to setpoint changes. The module also features a spring terminal block for quick and reliable wiring connections, simplifying installation and maintenance.

Compatibility and System Integration

The TM3AQ2G integrates seamlessly with the Modicon TM3 controller family. It offers full compatibility with Modicon M221, M241, and M251 logic controllers. This flexibility allows you to use the same analog output module across different controller platforms within the TM3 ecosystem. Furthermore, the module communicates with the controller via the bus connector, eliminating the need for complex wiring and reducing installation time.

Technical Specifications

Focusing on output performance, the TM3AQ2G generates both voltage and current signals across multiple ranges. For voltage outputs, the module supports -10 to 10 V and 0 to 10 V ranges. For current outputs, it handles 0 to 20 mA and 4 to 20 mA ranges. The load impedance requirements are 1 kΩ minimum for voltage outputs and 300 Ω minimum for current outputs, ensuring compatibility with most industrial actuators.

The resolution details are as follows: for the 0 to 10 V range, the LSB value is 2.44 mV; for the -10 to 10 V range, it is 4.88 mV. For current outputs, the LSB value is 4.88 µA for the 0 to 20 mA range and 3.91 µA for the 4 to 20 mA range. Moreover, the absolute accuracy reaches +/-0.1% of full scale at 25 °C, with a temperature drift of only +/-0.006% FS/°C. The repeat accuracy is +/-0.4% of full scale, and non-linearity stays within +/-0.01% FS.

The TM3AQ2G delivers a stabilization time of 1 ms and a conversion time of 1 ms plus 1 ms per channel plus one controller cycle. Output ripple is limited to 20 mV, ensuring clean and stable signal generation. Crosstalk between channels stays within 1 LSB, preserving signal integrity even when both channels are operating simultaneously.

Electrical and Isolation Characteristics

Power supply requirements for the TM3AQ2G include a 24 V DC external supply with limits of 20.4 V to 28.8 V. Current consumption is 35 mA at 5 V DC (no load) and 40 mA at 5 V DC (full load) via the bus connector, plus 30 mA at 24 V DC (no load) and 70 mA at 24 V DC (full load) via the external supply. Therefore, you must account for the higher current draw when all outputs are active.

Local signalling is provided by a green PWR LED for power status indication. Isolation is robust: the TM3AQ2G provides 500 V AC isolation between outputs and internal logic, and 1500 V AC isolation between outputs and power supply. This design protects your controller from potential ground loops and output faults. The module also carries CE marking, confirming compliance with European safety and EMC standards.

Mechanical and Environmental Parameters

The TM3AQ2G features a slim design, measuring 23.6 mm in width, 70 mm in depth, and 90 mm in height. It weighs only 0.1 kg, making it ideal for space-constrained panels. Mounting options include TH35-15 or TH35-7.5 DIN rails conforming to IEC 60715, or panel mounting with an optional fixing kit.

The module operates within a temperature range of -10 to 55 °C for horizontal installation and -10 to 35 °C for vertical installation. Storage temperature ranges from -25 to 70 °C. Relative humidity tolerance is 10 to 95% without condensation in operation and storage. The IP20 protection degree ensures safe installation in typical control cabinets.

Environmental compliance is confirmed by Schneider's Green Premium status. The TM3AQ2G contains no SVHC above the threshold and meets REACH and RoHS requirements. The warranty period is 18 months.

Installation Guidelines

Proper installation ensures optimal performance of the TM3AQ2G. Begin by securely mounting the module on a DIN rail or panel surface. The spring terminal block accepts up to 11 wires of 2.5 mm² cross-section with a 5.08 mm pitch, accommodating larger gauge wires for output connections. For signal wiring, use twisted shielded cables with a maximum length of 30 meters to maintain signal integrity and minimize noise pickup.

When connecting outputs, ensure correct polarity for both voltage and current signals. For current outputs, the module requires an external loop power supply. For voltage outputs, the load impedance must be at least 1 kΩ to maintain accuracy. Additionally, avoid routing analog output wires parallel to high-voltage or high-current cables to prevent noise coupling. For inductive loads, consider installing external suppression devices to protect the output circuitry.
