ABB 83SR07E-E GJR2392700R1210 Control Module

The module can be operated in any PROCONTROL station with an external power supply unit.

The module address is set automatically when the module is plugged into the PROCONTROL station. The telegrams received over the bus are checked by the module for error-free transmission, based on their test flags.

The telegrams sent from the module to the bus are marked with test flags. This way, error-free transmission is ensured. The user program is stored in a nonvolatile memory (EEPROM). Loading and changing the user program is done from the PDDS via the bus.

The module is ready for operation if a valid user list has been loaded. For communicating with the process and the power controller, the module uses the following type of voltage:

US operating voltage +24 V, internally branched into:

UK1 supplying the contacts of process interface 1

UK2 supplying the contacts of process interface 2

S11/S13 supplying the transducers of process interface 1

S21/S23 supplying the transducers of process interface 2

The voltages are short-circuit-proof and non-interfering. Operating voltages and external logic signals are based on reference conductor Z

The module essentially consists of:

- Process interfaces

- Station-bus interface

- Processing section

Process interfaces:In the process interfaces, the process signals are adapted to the internal signal level.

Station-bus interface: In the station-bus interface, the module signals are adapted to the bus. This is primarily a parallel/serial conversion.

Processing section :For processing the signals coming from the process and the bus, the module is equipped with a microprocessor which works with the following memory areas using an internal bus:
