Buy TM2AVO2HT | Schneider Modicon M238 Output Module
Product Introduction
The TM2AVO2HT analog output module enhances the Modicon M238 controller family with precise voltage control capabilities. Schneider Electric designed this module to deliver two independent analog outputs, each configurable for +/-10 V operation. Consequently, it suits applications requiring accurate actuator control, such as valve positioning or speed regulation.
This output module stands out due to its 11-bit plus sign resolution, which translates to a 9.8 mV per LSB value. Therefore, you achieve fine-grained control over your connected devices. Additionally, its fast 2 ms stabilization time ensures quick response to program changes, minimizing process delays.
Technical Specifications
Focusing on performance, the TM2AVO2HT module offers a conversion time of 2 ms plus one controller cycle. This means your system maintains real-time responsiveness. The measurement error stays within 0.5% of full scale at 25 °C, while the repeat accuracy reaches +/-0.1% FS. Furthermore, the temperature coefficient is only +/-0.01% FS/°C, ensuring stable operation across varying ambient conditions.
The module supports a resistive load with a minimum impedance of 3000 Ohm for voltage outputs. Its output ripple is limited to 1 LSB, preserving signal integrity. For electrical isolation, the TM2AVO2HT uses a photocoupler between channels and internal logic, providing 2500 V dielectric strength. This design protects your controller from potential field wiring faults.
Power requirements include an external 24 V DC supply, with limits from 19.2 V to 30 V. Current consumption totals 60 mA at 24 V DC external and another 60 mA at 5 V DC internal. Therefore, you must account for these values in your system power budget.
Mechanical and Environmental Parameters
The TM2AVO2HT features a compact footprint, measuring 23.5 mm in width, 70 mm in depth, and 90 mm in height. It weighs only 0.085 kg, making it lightweight for panel installations. For mounting, you can use a standard DIN rail (15 mm or 7.5 mm depth) with appropriate catalog parts like AM1DE200 or AM1DP200. However, avoid using AM1ED200 or DZ5MB200 with this module. Alternatively, panel surface mounting is possible using the provided hole layout.
Environmentally, this product carries Schneider Electric's Green Premium label, confirming compliance with sustainability standards. It has been compliant since 1039 and contains no SVHC above the threshold. The operating temperature range supports typical industrial environments, though specific limits are detailed in the full datasheet.
Installation Guidelines
Proper wiring ensures optimal performance of the TM2AVO2HT. Use a twisted shielded cable to minimize electrical noise interference. The removable screw terminal block simplifies connections; accept wire sizes as specified in the manufacturer's wiring requirements. Remember to pull out the clip-on lock by 8.5 mm (0.33 in) before securing wires.
When mounting, ensure the DIN rail is correctly installed. For panel mounting, follow the hole layout dimensions precisely. Additionally, maintain adequate spacing between the module and high-voltage cables to prevent coupling. The external 24 V DC supply must be stable and within the specified limits to avoid erratic output behavior.

Frequently Asked Questions (FAQ)
1. What controllers are compatible with the TM2AVO2HT?
This module is specifically designed for the Modicon M238 logic controller series. It integrates seamlessly via the controller's expansion bus.
2. Can I use this module for current output signals?
No, the TM2AVO2HT provides voltage outputs only (+/-10 V). For current outputs, consider other Schneider Electric analog modules.
3. How do I wire the module to reduce noise?
Always use twisted shielded cables and connect the shield to ground at one end. Keep signal wires away from power cables to minimize interference.
4. What is the maximum load I can connect?
The output supports resistive loads with impedance of 3000 Ohm or higher. Lower impedance may cause inaccurate voltage levels.
5. Is the module hot-swappable?
No, the TM2AVO2HT is not designed for hot-swapping. Always power down the controller before installing or removing the module.
