Siemens 6ES7194-4AB00-0AA0 M12 Compensation Plugs

Siemens 6ES7194-4AB00-0AA0 SIMATIC DP M12 compensation plugs with integrated Pt1000 enable reference-junction compensation for thermocouples connected to SIMATIC DP distributed I/O systems. The plug houses a Pt1000 temperature sensor that measures the local ambient temperature at the thermocouple junction, providing accurate cold-junction compensation. The M12 connector ensures a secure, robust interface to compatible DP modules in industrial environments where temperature conditions vary. By locating the reference sensor close to the thermocouple connection, this compensation plug helps minimize measurement errors caused by ambient temperature gradients along sensor wiring, improving the reliability of process temperature measurements. The part is explicitly designated as 6ES7194-4AB00-0AA0 and is used as a DP accessory for reference-junction compensation when thermocouples are connected to SIMATIC DP networks.
