The Schneider Electric TM2AMI2LT is an analog input module that accommodates two dedicated inputs for thermocouples. This device supports multiple thermocouple types including J, K, and T, making it versatile for a variety of applications requiring temperature monitoring. The specified input ranges are -200°C to 760°C for type J, -270°C to 1370°C for type K, and -270°C to 400°C for type T, allowing it to cover a wide spectrum of temperature measurement needs.
Featuring a resolution of 12 bits, this module offers a sampling duration of 200 milliseconds per channel, providing responsiveness in real-time temperature detection. It stipulates a measurement error of ±0.2% of the full scale at 25°C, contributing to reliable data accuracy. The temperature coefficient is specified at ±0.006% FS/°C, ensuring exceptional stability even with temperature variations. The repeat accuracy is at ±0.5% FS, which facilitates consistent measurement outcomes over time.
The input impedance for thermocouples is greater than or equal to 1 MΩ, allowing for effective signal integrity. The module operates on a power supply voltage of 24 V DC, with a tolerance range of 20.4 V to 28.8 V. Current consumption is 30 mA when using an external 24 V DC supply and 60 mA at 5 V DC internally.
Electrical protection is rated at 500 V dielectric strength between the I/O and external supply circuit and 2500 V between the I/O and internal logic. This provides assurance against voltage surges. The physical dimensions of the module are compact, measuring 23.5 mm in width, 70 mm in depth, and 90 mm in height, with a total weight of approximately 0.085 kg (0.19 lb), making it suitable for installations in confined spaces.
