Characteristics

Binary Outputs

The binary outputs are relay contacts.

The 8 outputs are isolated from each other. www.cniacs.com In addition, they are isolated from the internal electronics by means of an optocoupler.

All 8 relay contacts have independent outputs and there are no common circuits.

The command outputs to the process equipment can be executed either directly or in conjunction with the command output monitoring module.

The Command Output Monitoring Module checks the output circuits (1 out of n times). For more details, refer to the Command Output Monitor data sheet.

The following modules with command output monitoring functions are supported:

– 560CIG10

– 560CID11

– 520CSD01

Output formats unipolar, bipolar or real-time zero www.cniacs.com (4 … 20 mA) are configurable via software parameters. 20 mA) can be configured via software parameters.

Characteristics

Analogue outputs

Each output has a digital-to-analogue converter (DAC) for converting digital values into analogue signals. the resolution of the DAC is 11 bits plus sign.

The received output value is stored until a new value is received. The output channels are set to 0 % after powering up or restarting the communication module.

The output channels are isolated from the power supply, but not between the two channels.

Power input

The power required by the module is supplied through the RTU520 I/O bus connector. In addition, 24 VDC (UE) is required (e.g. from the 560PSU40/41).

The UE voltage must be supplied externally and connected to the UE connector.

Applications

The 520PTD01 circuit board is used for direct connection of PT100 temperature transmitters.

Up to six transmitters can be connected to the board. The measuring range is ± 200 °C.

Special features

Basic checks and calculation-intensive cyclic processing functions are already performed on the module, thus reducing the burden on the communication unit.

Relevant changes are transmitted as events via the WRB I/O bus.

The 6 differential inputs are not isolated from the RTU500 series power supply.

The 520PTD01 converts the analogue signal to 4096 steps (12 bits) and measures 100%.

The differential inputs are protected against static www.cniacs.com and dynamic overvoltage by protection circuitry. A low-pass filter suppresses non-line frequency AC interference.

Two additional channels are used for automatic zero calibration.

The line frequency is configurable in the configuration tool.

The microcontroller uses these configuration parameters to set up the A/D converter.

The microcontroller controls the A/D converter and performs all processing functions on the configured measurements within a conversion time of 80 ms (50 Hz).

In addition, the microcontroller communicates with the RTU system bus. All configuration features and processing parameters are downloaded from the CMU via the RTU system bus.

The module is connected to the RTU WRB I/O bus (wired OR bus) via adapter 520ADD01.

During initialisation and operation, the module performs a series of tests. If a fault occurs, it will be reported to the CMU.

All fault conditions affecting the functionality of the module are displayed as general fault signals with the red LED “ERR”.

Module faults are detected by the communication unit.
