ABB GJR2389800R1210 81ET03 Temperature Input Module

The ABB GJR2389800R1210 81ET03 Temperature Input Module is a versatile and reliable solution for various sensor-based applications. This module serves as a replacement for multiple sensor modules and is designed to handle a wide range of measuring currents, including thermocouples and resistance thermometers, suitable for 4-wire connections. Each measuring loop is monitored separately, ensuring precise and accurate temperature readings.

Key Features and Specifications

The 81ET03 module is designed to be easily integrated into any PROCONTROL station with an external power supply unit and features a standard interface for the PROCONTROL station bus. It transmits switched sensor signals (in the form of telegrams) through the station bus to the PROCONTROL bus system. The telegrams undergo control before transmission and are marked with test voltages. The individual measuring loops are activated via a multiplexer and are thus individually potential-free. Sensor signals are transferred to the processing section as potential-isolated signals. Up to four limit signals can be generated for each measured value. The module supports various types of sensors, including different thermocouples and resistance thermometers, and is equipped with an automatic calibration function for resistance thermometer inputs.

Practical Applications and Benefits

This temperature input module is ideal for a wide range of applications where accurate temperature measurement is crucial. Whether it's in industrial automation, HVAC systems, or process control, the 81ET03 module ensures reliable performance and precise data. Its versatility, ease of integration, and advanced features make it a valuable addition to any system requiring temperature monitoring. With its robust design and high-quality construction, this module is built to last, providing long-term value and peace of mind for users.
