HONEYWELL 8C-PAOHA1 (51454469-275) Analog Output Module with HART

The Honeywell 8C-PAOHA1 Analog Output (AO) Module is designed for delivering precise 4-20 mA output signals for HART-capable devices such as actuators and recording instruments. It offers enhanced diagnostic capabilities, redundancy options, and configurable fail-safe behaviors for optimal performance in critical industrial applications.

Key Features

• Fail-Safe (FAILOPT) Configuration: Each channel can be individually configured to either HOLD LAST VALUE or SHED to a SAFE VALUE in case of a fault, with default behavior to zero output if the module fails.
• Open-Wire Detection: The module can detect open field wiring and alerts through a Channel Soft Failure indication.
• Optional Redundancy: Allows for redundancy to ensure continuous operation and reliability.
• HART Protocol Compatibility: Supports multivariable communication with HART-enabled field devices.
