ABB AO810/AO810V2 Analog Output Module has 8 unipolar analog output channels. To supervise the communication to the D/A-converters 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 reported when supply voltage to output circuitry is 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 current is less than the output set value and the output set value is greater than 1 mA.
- 8 channels of 0...20 mA, 4...20 mA outputs
- OSP sets outputs to predetermined state upon error detection
- Analog Output is to be short circuit secured to ZP or +24 V
