The input module is used as a substitute for the following input modules with transmitters:
81EA01-E/R1010 without correcting function
– 2-wire transducer, 4 … 20 mA, with supply from the module
– 4-wire transducer, 0/4 … 20 mA, with supply from the module
– 4-wire transducer, 0/4 … 20 mA, with external power supply
81EA01-E/R1111 with correcting function and without output of the uncorrected value (raw value)
– 2-wire transducer, 4 … 20 mA, with supply from the module
– 4-wire transducer, 0/4 … 20 mA, with supply from the module
– 4-wire transducer, 0/4 … 20 mA, with external power supply
81EA01-E/R1112 with correcting function and output of the uncorrected value (raw value)
– 2-wire transducer, 4 … 20 mA, with supply from the module
– 4-wire transducer, 0/4 … 20 mA, with supply from the module
– 4-wire transducer, 0/4 … 20 mA, with external power supply
The module incorporates a total of 5 function units. Each function unit may be used for any type of input mode. Any combination is possible. The allocation as well as the settings of all the parameters can be programmed easily using the configuration list. The programmed values are stored in an EEPROM to ensure that they are not lost in the event of a power failure. They can be changed any time. Every analog signal can be assigned up to 4 limit values.
In an input module, up to 5 independent correction or filter calcuations can be carried out. Programming is done by structuring function blocks. The conditions relevant to this application are to be taken into consideration.
The module can be plugged into any PROCONTROL station with an external power supply unit. It is equipped with a standard interface for the PROCONTROL station bus.
The module sends the converted input signals in the form of telegrams over the station bus to the PROCONTROL bus system. The telegrams are checked before they are sent and marked with test flags. This ensures that the receiving module can check them for error-free transmission.
The telegrams received over the station bus, e.g. for correction calculations, are checked by the module for error-free transmission based on their test flags.
Provision is made to eliminate interference among the function units of the module and the station bus. A short-circuit-proof and monitored transmitter power supply is available for each function unit, suitable for the various applications.
A response of the internal monitoring circuits or of the input signal monitoring function is indicated in the form of a disturbance annunciation ST (general disturbance) on the front panel of the module.
