Honeywell 16644995-001 | Digital Input Output Module

Product Description

The Honeywell 16644995-001 digital input/output module is engineered to expand discrete signal handling capabilities within the Experion PKS distributed control system. Designed for direct use with Honeywell C300 controllers, this module enables stable acquisition of digital field signals while delivering dependable discrete output control for industrial equipment.

Built for continuous duty in demanding process environments, the module combines electrical isolation, onboard diagnostics, and a compact mechanical design. It is intended for installation within Honeywell C300 I/O assemblies, providing seamless communication with the controller backplane and consistent performance across long operational lifecycles.

Key Functional Capabilities

The 16644995-001 supports high-density digital signal management, allowing flexible assignment of channels for monitoring or actuation depending on the connected I/O assembly. Its architecture ensures deterministic signal processing, making it suitable for safety-critical and mission-critical control tasks.

Integrated LED indicators provide immediate visual feedback for channel status, communication health, and module-level diagnostics, reducing commissioning and troubleshooting time.
