Honeywell MU-PDOY22 80363975-100 Digital Output Processor Module

Product Description

The Honeywell MU-PDOY22 is a high-density digital output processor engineered for use in Honeywell TDC 3000 and Experion Distributed Control Systems. This module delivers 32 independent digital output channels designed for dependable control of field devices requiring low to moderate power switching.

Built around open-collector, current-sinking transistor outputs, the MU-PDOY22 is optimized for driving interposing relays, solenoid valves, indicator lamps, and compact actuators. Electrical isolation is achieved through compatible Field Terminal Assemblies (FTAs), ensuring signal integrity and protection within critical control environments.

The module supports redundant system architectures, making it suitable for high-availability process control applications where continuous operation is essential. It is intended for installation in control rooms or protected enclosures and complies with CE regulatory requirements.

Key Functional Characteristics

The MU-PDOY22 provides stable, predictable switching behavior across all output points. Its transistor-based design allows fast response times and long service life compared to mechanical alternatives. Compatibility with multiple Honeywell FTAs enables flexible system design and straightforward integration into existing DCS infrastructures.

Frequently Asked Questions

Can the MU-PDOY22 be used in redundant controller configurations? Yes. The module is designed to operate within redundant Honeywell DCS architectures for improved system availability.

Does the module provide direct field isolation? Isolation is achieved through the selected Field Terminal Assembly rather than within the module itself.

Is it suitable for high-power loads? No. The open-collector outputs are intended for light-duty loads and should be used with interposing relays for higher power applications.
