Siemens SIPLUS S7-1200 SM 1231 TC 8AI Thermocouple Module
Siemens SIPLUS S7-1200 SM 1231 TC 8AI thermocouple analog input module.
The Siemens SIPLUS S7-1200 SM 1231 TC 8AI is an analog input module designed for precise temperature measurement using thermocouples within the S7-1200 PLC series. It supports various thermocouple types (J, K, T, E, R, S, B, N, C, TXK/XK(L)) and can also measure low-level analog signals in the ±80 mV range. This SIPLUS variant features conformal coating for enhanced protection in harsh environments, operating between -20°C and +60°C.
This module offers 8 analog input channels, each with a resolution of 15 bits + sign. It provides features like open line detection and cold junction compensation for accurate readings. The SM 1231 TC can be mounted on a DIN rail or directly bolted to a wall, making it versatile for different installation requirements.
