Schneider TM2AMM6HT Analog I/O Module Overview
The Schneider TM2AMM6HT is a high-performance input/output analog module designed for use with Modicon M238 logic controllers. This compact module offers four analog inputs and two analog outputs, supporting both current (4...20 mA) and voltage (0...10 V) signals. Its 12-bit resolution ensures precise measurement and control, making it a reliable choice for industrial automation applications requiring accurate analog signal processing.
Key Features and Technical Specifications
The TM2AMM6HT provides four non-differential high-level analog inputs and two analog outputs, each configurable for current or voltage. The input resolution is 12 bits with an LSB value of 2.5 mV for voltage and 4 µA for current. The module delivers a conversion time of 20 ms plus one controller cycle, ensuring responsive operation. For output, the stabilization time is also 20 ms, with a repeat accuracy of ±1% FS for output and ±0.5% FS for input.
Electrical isolation between channels and internal logic uses photocouplers, with dielectric strength rated at 1500 V between I/O and external supply. The module operates on a 24 V DC supply (19.2...30 V range) and consumes 60 mA at 5 V DC internal and 80 mA at 24 V DC external. Connection is via a removable screw terminal block.
Input and Output Performance
The analog inputs accept 4...20 mA or 0...10 V signals with a permissible continuous overload of 13 V for voltage and 40 mA for current. Input impedance is ≤250 MΩ for current and ≥1 MΩ for voltage. For analog outputs, the load must be resistive: ≤300 Ω for current mode and ≥2000 Ω for voltage mode. Measurement error is ±0.5% of full scale at 25°C for both ranges, with a temperature coefficient of ±0.02% FS/°C. Non-linearity is ±0.4% FS for current and voltage, and total error is ±1.5% FS for both current and voltage outputs.
Physical and Environmental Characteristics
The module measures 0.93 in (23.5 mm) wide, 2.76 in (70 mm) deep, and 3.54 in (90 mm) high, weighing only 0.19 lb (0.085 kg). It requires a shielded cable for reliable operation and is compatible with Advantys OTB and Twido ranges. The module's compact size makes it ideal for space-constrained control cabinets.
Applications and Benefits
The Schneider TM2AMM6HT is well-suited for process control, machine automation, and monitoring systems where precise analog signal handling is critical. Its 12-bit resolution and low error rates ensure accurate data acquisition and control. The combination of current and voltage inputs and outputs provides flexibility for various sensor and actuator types. Engineers will appreciate the module's fast conversion time and robust electrical isolation, which enhance system reliability in industrial environments.
For procurement professionals, the TM2AMM6HT offers a cost-effective solution for expanding the analog capabilities of Modicon M238 controllers. Its straightforward installation and compatibility with Schneider's ecosystem reduce integration efforts. Overall, this module delivers dependable performance for demanding automation tasks.
