Product Overview
6ES7650-1AF51-2XX0 terminates eight thermocouple channels for an ET 200M thermocouple input module through a SIMATIC PCS 7 marshalled termination assembly.
An integrated Pt100 reference-junction sensor supports temperature compensation, while fixed field terminations reduce measurement errors and a green LED indicates available module power.
Key Functions
Eight-channel thermocouple termination
Each field channel provides TC+, TC− and shield connections, with signal connections routed to the I/O module through J1.
Integrated cold-junction sensing
The built-in Pt100 sensor is thermally coupled to the field terminals for reference-junction measurement.
Fused power distribution
Input power passes through the module power fuse, with a green indicator showing the presence of module power.

Frequently Asked Questions
Which ET 200M input modules can I connect to 6ES7650-1AF51-2XX0?
The assembly interfaces with 6ES7331-7PF10-0AB0 from E-Stand 4 and with 6ES7331-7PF11-0AB0.
Does 6ES7650-1AF51-2XX0 support Serviceable supply for mobile equipment?
A Pt100 reference-junction sensor is already built into the terminal assembly and thermally coupled to its field terminals.
Can I unplug the thermocouple terminal blocks on 6ES7650-1AF51-2XX0?
The thermocouple field connections are fixed to reduce measurement errors.
Which replacement module-power fuse belongs in 6ES7650-1AF51-2XX0?
The module supply uses a 0.5 A GMA-0.5A fuse, available from Siemens as spare part A5E01568885.
Where do I terminate cable shields on 6ES7650-1AF51-2XX0?
Each channel has a shield connection and the assembly has a shield ground stud for connection to earth.
Can I fit a power-monitor board to 6ES7650-1AF51-2XX0?
The power-monitor board option is not available on this thermocouple MTA.
Can I use 6ES7650-1AF51-2XX0 in a redundant thermocouple input pair?
Neither this MTA nor the connected eight-channel thermocouple module supports redundant operation.
