Product details

The 6ES7231-5QF50-0XB0 is an SM 1231 TC analog input module for the SIMATIC S7-1200 G2 controller, providing 8 channels for thermocouples type J or K. This module plugs into the system's backplane and is addressed automatically via the controller's I/O map. It is the second-generation variant, so it will not fit the first-generation S7-1200 base units without a system upgrade.

Module dimensions are 150 x 47 x 110 mm, occupying one slot on the S7-1200 G2 rail. It uses the standard spring-cage terminal for field wiring; no separate base or carrier required. For panel layout, allow additional clearance for thermocouple extension wire routing adjacent to the module.

Confirm lead-time with the distributor for your planned build horizon.
