Product Overview
The Honeywell MC-PDOY22 (Part No. 80363975-150) is a 32-point digital output processor designed for precise and reliable control in process automation systems. It belongs to the Experion and TDC3000 I/O family, offering seamless integration with standard 24 Vdc and 120/240 Vac field termination assemblies (FTAs). This module is conformally coated for enhanced durability in harsh industrial environments, ensuring long-term protection against moisture and contaminants.
Moreover, the MC-PDOY22 supports full galvanic isolation and high surge immunity, meeting ANSI/IEEE C37.90.1-1978 standards. It’s the ideal choice for users demanding high-density output control in critical plant operations.
Functional Highlights
- 32 Isolated Output Channels: Provides open-collector NPN transistor or relay output configuration options.
- Flexible Load Handling: Supports both 24 Vdc current-sinking and 120/240 Vac relay outputs.
- Galvanic Isolation: Optical coupler-based protection up to ±42.4 Vdc or 1500 Vac rms.
- Reliable Switching: Maximum load current up to 5 A per FTA, ensuring stable signal output.
- Fast Response Time: 200 ms (transistor type) or 10 ms (relay type) switching capability.
- Extended Service Life: Up to 10 million mechanical operations per relay output.
In addition, each module supports redundant operation and automatic failure detection, maintaining continuous process control even during hardware replacement.
