Function
The 8C-PAON01 is a High-Level Analog Output Module designed to deliver constant current outputs to actuators, recording devices, or indicators. It supports features for reliability and diagnostic monitoring.
Notable Features
- Extensive Self-Diagnostics:
- Ensures reliable operation and simplifies troubleshooting.
- Optional Redundancy:
- Can be paired with a redundant IOTA for increased reliability.
- Safe-State (FAILOPT) Configurability:
- Per-channel configurable behavior:
- HOLD LAST VALUE: Retains the last known value in case of failure.
- SHED TO SAFE VALUE: Outputs a predefined safe value.
- Defaults to 0 mA if device electronics fail.
- Open-Wire Detection:
- Detects and annunciates open field wiring issues.
- Output Read-Back:
- Monitors actual output and alarms on discrepancies.
