Key specifications
4 analog inputs for thermocouples
Supported types: J, K, T, E, R, S, N, C, TXK/X
Designed for SIMATIC S7-1200 PLC series
Industrial-grade thermal measurement accuracy
How to use
Installation involves mounting the module onto the DIN rail adjacent to the S7-1200 CPU or other expansion modules. Once physically connected via the integrated bus connector, the module must be configured within the TIA Portal software environment. Users should define the specific thermocouple type for each input channel and set the appropriate scaling parameters to ensure accurate temperature readings. Proper shielding and grounding of thermocouple wiring are recommended to minimize electromagnetic interference.
What to consider before purchase
Verify compatibility with your existing S7-1200 CPU firmware version
Ensure the thermocouple types used match the supported list
Check available space on the DIN rail for expansion modules
Usage recommendations
Always ensure that the power supply is disconnected before installing or removing the module to prevent electrical damage. Use shielded twisted-pair cables for thermocouple connections to maintain signal integrity in high-noise industrial environments.
