AO810 Analog Output Module
Description
The AO810 Analog Output Module features 8 unipolar analog output channels. To supervise the communication to the D/A converters, the serial data is read back and verified. The open-circuit diagnostic is received during the readback.
The module performs self-diagnostic cyclically. The module diagnostics include process power supply supervision, reported when the supply voltage to output circuitry is too low. This 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.
Four different types of MTUs can be used. The TU830 Extended MTU and the TU810 (or TU814) Compact MTU enable wire connection to the devices without additional terminals. The TU812 Compact MTU has a D-Sub 25 pin (male) connector for connection to the process.
Features
- 8 channels of 0...20 mA, 4...20 mA outputs.
- OSP sets outputs to predetermined state upon error detection.
- Analog Output is short circuit secured to ZP or +24 V.
