AO810V2 3BSE038415R1 Analog Output 8 ch

The AO810/AO810V2 Analog OutputModule has 8 unipolar analog

output channels. To supervise the communication to the D/Aconverters the serial data is read back and verified. The opencircuit

diagnostic is received during the readback. The module performs

self-diagnostic cyclically. The module diagnostics includes process

power supply supervision,which is reportedwhen supplyvoltage to

output circuitryis to low. The error is reported as a channel error. The

channel diagnostic includes fault detection of the channel (only

reported on active channels). The error is reported if the output

currentis less than the output setvalue and the output setvalue is

greater than 1 mA.

It is very reliable to control the system with PLC. This is because PLC has taken many measures in both hardware and software to ensure that it can work reliably. In fact, if PLC does not work reliably, it cannot be used in industrial environment, and it is not PLC.

In terms of hardware:

The input and output circuits of PLC are electrically isolated from the internal CPU. Its information is transmitted by optocoupler or electromagnetic device. In addition, the CPU board also has shielding measures against electromagnetic interference. Therefore, it can ensure that the PLC program can operate normally without external electrical and magnetic interference.

The components used by PLC are mostly contactless, highly integrated, and not too many, which also provides a material basis for its reliable work.

In terms of mechanical structure design and manufacturing process, in order to make PLC work safely and reliably, many measures have also been taken to ensure PLC vibration and impact resistance. The ambient temperature can be as high as 50 ℃, and some PLCs can be as high as 80-90 ℃.
