Applications

Analogue control outputs for sequential or closed-loop control, display instruments, measurement recorders, etc,

The analogue output board 520AOD01 can be connected to measuring and recording instruments, etc.

The board 520AOD01 has 2 output channels which can be configured for different voltage or current output ranges.

The module 520AOD01 can process the following types of signals:

– Analogue setpoint commands

– Floating-point setpoint commands

The following output ranges can be configured independently for each channel via on-board switches:

– ± 2.5 mA

– ± 2.5 mA ± 5 mA

– ± 10 mA

– ± 20 mA (4…20 mA) .20 mA)

– ± 1.25 VDC

– ± 2.5 VDC

– ± 5 V DC

– ± 10 V DC

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.
