MC-PDIY22 51404125-150 Honeywell TDC 3000 Input Card New

Product Description

The MC-PDIY22 (51404125-150) is a high-density Discrete Input I/O Processor (IOP) card designed for the Honeywell High-Performance Process Manager (HPM) chassis. Operating within the TDC 3000 and TPS distributed control systems, this module serves as a robust interface for 32 isolated digital input channels. It is engineered to capture ON/OFF status signals from field-mounted switches, relays, and sensors, converting them into digital data for real-time process monitoring and interlock execution.

The MC-PDIY22 (51404125-150) is recognized for its industrial-grade isolation, which protects the core logic and system backplane from field-side electrical surges. This module supports hot-swappable replacement, allowing for maintenance and hardware upgrades without requiring a system shutdown. Often cross-referenced with the 51404125-100 and 51402573-150 revisions, this processor ensures long-term lifecycle support for legacy TDC 3000 architectures. We provide this module as 100% Brand New and factory-original equipment, adhering to the highest standards of technical expertise and reliability.

FAQ

• Is the MC-PDIY22 (51404125-150) compatible with the 51404125-100 revision?Yes, the -150 part number is typically the updated revision or conformally coated version of the -100 series, offering backward compatibility within the HPM rack.

• Does this card require a specific Field Termination Assembly (FTA)?Yes, the MC-PDIY22 must be connected via an I/O cable to a compatible Honeywell FTA, which provides the terminal points for field wiring.

• Can this module be used in an APM chassis?The MC-PDIY22 is specifically designed for the HPM (High-Performance Process Manager) architecture. While similar to APM cards, firmware and hardware revisions should be verified for specific cross-platform use.
