Product Overview
The Honeywell 8C-PAOHA1 is a high-level analog output module designed to deliver precise 4-20 mA signals to HART-enabled actuators and recording devices.
Moreover, it supports redundancy configurations and per-channel fail-safe (FAILOPT) behavior, ensuring continuous operation during system faults. This module is suitable for critical industrial applications requiring reliable, precise output control.
Functional Highlights
- Fail-Safe Configurability: Each channel can HOLD LAST VALUE or SHED to SAFE VALUE, defaulting to zero on failure.
- Open-Wire Detection: Alerts users of open field wiring via channel soft failure notifications.
- Redundancy Support: Optional redundant configuration increases system reliability and minimizes downtime.
- HART Protocol: Fully compatible with multivariable HART communication for intelligent field devices.
In addition, the module ensures rapid response time of 80 ms and a redundancy switchover gap of 10 ms, maintaining operational stability.
