8C-PAOH51 Analog Output with HART Function
The Analog Output (AO) Module delivers high-level constant current to actuators and recording/indicating devices.
Notable Features
- Extensive self diagnostics
- Optional redundancy
- HART-capable, multivariable instruments
- Safe-state (FAILOPT) behaviors configurable on a per channel basis
- Non-incendive output (No external user supplied power)
Safe-state Behavior (FAILOPT)
The Series 8 AO module supports the FAILOPT parameter on a per channel basis. The user can configure each channel to either HOLD LAST VALUE, or SHED to a SAFE VALUE. The output will always go to zero, the safe state, if the IOM device electronics fail.
Open-wire Detection
This Series 8 IO function can detect and annunciate open field wire with a Channel Soft Failure indication.
