ABB 81EA04C-E GJR2393400R1210 Input Module for Analog Signals

81EA04C-E GJR2393400R1210 Analog Input Module

The 81EA04C-E is a Analog Output Module, manufactured and designed by ABB as part of the P14 Series used in the ABB PROCONTROL P system.

This 81EA04C-E input module is used for current signal input throughout the signal ranges of 0 ... 5 mA, 0 ... 20 mA, 4 ... 20 mA or 0 ... 50 mA, independent of the potential.

The process part of the module is electrically isolated against the processing section and against the USA, USB, and Z potentials.

The input channels are formed by high-resistance instrument amplifiers and are mutually isolated by an impedance of 400 kΩ. This allows input of current signals on different potential levels.

The module allows for a maximum of four independent correcting or filtering calculations using structurable function blocks.

The correcting variable as well as the two auxiliary correcting variables can be specified for each function block either from the function units or alternatively via the bus.

Output of the corrected values always is via the bus. In addition to the corrected values, the limit signals of analog signals and status messages from function blocks are put out to the bus system.

Features

This module can be plugged into any station belonging to the PROCONTROL bus system. lt is equipped with a standard interface for the PROCONTROL station bus.

It transmits the converted input signals in the form of telegrams via the station bus to the PROCONTROL bus system. The telegrams are monitored before being sent and are given parity bits. This way, checking for fault-free transmission on the receiver side is ensured.

The telegrams received via the station bus are checked by the module on the basis of their parity bits for fault-free transmission.

The individual function units are mutually non-interfering as well as non-interfering with the processing section (station bus).

For each function unit, one of the four signal ranges 0 ... 20 mA, 4 ... 20 mA, 0 ... 5 mA or 0 ... 50 mA can be selected.

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

Activation of internal monitoring circuits is also indicated as disturbance annunciation SG (module disturbance) on the module front.

Disturbance voltages on the input lines are suppressed by means of protective circuits inside the module.
