ABB 81ET03K-E GJR2389800R1210 Input Module

81ET03K-E GJR2389800R1210 Input Module 

The 81ET03K-E module contains 16 function units which may optionally be used for measuring circuits including thermocouples and/or resistance thermometers designed for 2 or 4-wire connection.

Each measuring circuit uses:

-1 or 2 function units for thermocouples (depending on the type of compensation)

-1 function unit for resistance thermometers connected by a 2-wire connection

-2 function units for resistance thermometers connected by a 4-wire connection.

Each measuring circuit is monitored separately. Up to four limit signals can be generated for each measured value.

Sensors used for differential temperatures

- Thermocouples NiCr-Ni

- Thermocouples Fe-CuNi

Special sensors

-Potentiometric sensors

Features

The 81ET03K-E module can be plugged into any PROCONTROL station with redundant 24 V supply and is equipped with a standard interface to the PROCONTROL station bus.

The module sends the converted input signals, in the form of telegrams, to the PROCONTROL bus system via the station bus. The telegrams are checked before they are sent, and are marked with test flags. This way, checking for fault-free transmission to the receiving module is ensured.

The individual measuring circuits are activated via a relay multiplexer and are therefore individually potential-free. The input signals are transmitted to the processing section as potential-isolated signals. Thus, non-interaction between process and bus is ensured.

Adaptation to the temperature sensor used, the measuring range and (for thermocouples) the type of compensation is made separately for each measuring circuit via the programming, diagnosis and display system (PDDS). This setting does not require any subsequent recalibration.

A response of internal monitoring circuits or of the input signal monitoring function is indicated as disturbance annunciation ST (general disturbance) on the module front.

A response of internal monitoring circuits is indicated as an SG disturbance (module disturbance) on the module front.
