Product Details
The hardware of the bay control terminal REC 580 comprises a number of different modules chosen to suit the particular requirements. The following modules are available:
• Central processing module and corresponding interfaces
• Process bus (MVB) controller module
• Input transformer module
• Insulating transducers module for mA, V signal inputs
• Analog input modules • Binary Input module
• Binary Output module
• Auxiliary supply modules
• Housing with backplane
• Optical interface for communication with other bays and the station control level (LON)
• Optical interface for communicating with intelligent sensors and actuators, (PISA)
• Optical interface for an extension rack (MVB)
• Front socket for connecting a service PC
Input transformer modules
The purpose of the input transformers is to electrically insulate the analog input variables and reduce their signal level to a value suitable for processing by the electronic circuits. A REC 580 bay control terminal can contain up to 2 transformer units. Depending on the type a maximum insertion of 13 transformers per transformer module is possible.
Isolating transducer module
The isolating transducer module enables the galvanically separated small signals (±20 mA, ±5 mA, ±10 V) to be transmitted to the analog input module. Each channel can either be set or cut out separately for the ranges stated above.
Analog input modules
In the analog input modules, the analog variables are filtered to eliminate the aliasing effect and to suppress high frequency interference. Depending on the particular type of analog input module in use, the analog signals are then sampled at a rate of either 1000 Hz (50Hz) resp. 1200 Hz (60 Hz) to convert them into digital signals. The A/D conversion has a dynamic response of 16 Bit. A digital signal processor (DSP) pre-processes the signals before transferring them to the memory in the central processor module.
An analog input module has a capacity of 16 signals and according to system configuration, there can be up to 2 modules in a rack to be applied if input transformer modules and/or isolating amplifier units are used.
Processor modules
Processor modules include essentially the processor part itself with Motorola microprocessors and communication controller modules for the VME bus, the station bus type LON and the process bus type MVB. They control the interface on the front of the terminal for connecting the service PC, the interface at the rear of the terminal for communicating with the station control system according to LON, and the interface at the rear to the process bus type MVB.
After the signals have been conditioned and pre-processed in other modules the processor modules execute the algorithms and logicfunctions as determined by the configuration and application program of the individual REC 580. The processor modules then transfer binary signals to the output modules for actuating the auxiliary output relays.
