It uses a sigma-delta measurement principle. Two analog inputs per module allow up to four channels per slot when using two modules. The sigma-delta converter provides noise immunity for long cable runs — max shielded cable length 100 m to the sensor, loop resistance limit 20 Ω (2.7 Ω max for Cu10 loops). Group error and external fault indicators (red SF and EXTF LEDs) signal broken sensor or wiring issues without needing the diagnostic buffer. The module uses non-pluggable I/O terminals — wiring direct to the front terminal block, and the 80 mm height matches standard enclosure cutouts.","metaTitle":"Siemens 6ES7231-7PB22-0XA0 Analog Input RTD Module, 2-Channe","metaDescription":"2-channel RTD module for S7-1200, sigma-delta measurement, supports Pt100/Ni1000/Cu10, 80x71.2x62mm, active production.
