AO815 3BSE052605R1 Analog Output Module
Description
The AO815 Analog Output Module features 8 unipolar analog output channels. The module performs self-diagnostic cyclically.
Features
- 8 channels of 4...20 mA outputs.
- OSP sets outputs to predetermined state upon error detection.
- 1 group of 8 channels isolated from ground.
- Analog Output is short circuit secured to ZP or +24 V.
- 12-bit resolution.
- HART pass-through communication.
Module diagnostics include:
- External Channel Error: Reported (only on active channels) if the process power supply voltage to output circuitry is too low or the output current is less than the output set value and the output set value is greater than 1 mA (open circuit).
- Internal Channel Error: Reported if the output circuit cannot provide the correct current value.
- Module Error: Reported in case of Output Transistor Error, Short Circuit, Checksum Error, Internal Power Supply Error, or Watchdog error.
The module supports HART pass-through functionality with point-to-point communication. The output filter must be enabled on channels used for HART communication. Shielded field cables are required for process connections if HART is used.
Four different types of MTUs can be used: TU830 Extended MTU and TU810 (or TU814) Compact MTU for wire connection without additional terminals, and TU812 Compact MTU with a D-Sub 25 pin (male) connector for process connection.
