ABB GJR2391500R1210 81EU01h-E Input Module

Universal Input Module for Binary and Analog Transmitters 81EU01 -- E/R1210：

Functional characteristics:

Processing is performed on the active and on the non ---active module in parallel. In the case of a redundancy changeover, the non ---active module takes up processing in a bumpless take ---over. Bumpless condition is ensured by dual acquisition and processing of the input signals. Active and non ---active modules are self ---monitoring and signal module disturbances to the respective 88TR01 redundancy control module over the SSG line. All process connections (connector X21) of the redundant partner modules are connected in parallel through the station wiring. The input resistors (loads) are switched on for the active module and off for the non ---active module. The contact and transducer supplies are on for both modules. For diagnosis purposes, non ---active modules send a live-sign telegram to the bus.
Multi-type input support: It can connect various types of transmitters, including single-pole and double-pole contacts (with or without line monitoring), inductive sensors in accordance with NAMUR DIN 19234, electronic transmitters, two-wire and four-wire current signal analog transmitters (such as 4...20mA, 0...20mA, 0...5mA, etc.), thermocouples and thermal resistance thermometers, etc. Each functional unit can be configured as any type of input mode, and any combination is feasible.
Signal conversion and transmission: The received input signal and/or the converted input signal are transmitted to the Procontrol bus system through the station bus in the form of a message. Before transmission, the message will be checked and parity bits will be added to ensure fault-free transmission at the receiving end. At the same time, the parity bits of the messages received through the station bus will also be checked.
Diagnosis and display: When the internal monitoring circuit or the input signal monitoring circuit responds, it will be displayed in the form of interference signals ST (general interference signal) and SG (module interference) in front of the module, which is convenient for timely detection and handling of faults.
Parameter setting and storage: Parameter assignment and settings can be easily programmed via configuration tables. The programmed values ​​are stored in EEPROM and will not be lost even in the event of a power failure. They can be changed at any time.

Application areas:

Mainly used in ABB Procontrol P14 system, widely used in automated production process control in power, chemical, metallurgy, water treatment and other industries. It can be used as an input module of PLC or DCS system to collect and monitor various types of sensors and switch signals on site.
