Pulse Accumulation Module 8C-PDIPA1 51454471-375 Honeywell

Product Description

The 8C-PDIPA1 (P/N: 51454471-375) is a high-density, hybrid Digital Input module for the Honeywell Experion PKS Series 8 / C300 platform. It combines standard 24VDC status monitoring with high-speed pulse counting, offering flexible input functionality in a single module.

The module features a 32-channel configuration, where channels 1–16 are software-configurable for either pulse accumulation or frequency measurement, and channels 17–32 operate as standard digital inputs. This hybrid architecture enables simultaneous discrete monitoring and pulse totalization, reducing cabinet I/O footprint and simplifying wiring.

Technical Specifications

Application Scenarios

The 8C-PDIPA1 is ideal for multi-functional process skids, where both:

• Status monitoring (valve limits, motor run/stop)

• Pulse totalization (from flowmeters or encoders)

are required on a single module, reducing the number of I/O cards and simplifying cabinet wiring in industrial control systems.

Frequently Asked Questions

Q: Can all 32 channels be used for pulse accumulation?
A: No. Pulse accumulation and frequency measurement are supported only on channels 1–16. Channels 17–32 operate as standard digital inputs.

Q: What types of sensors are compatible with the pulse channels?
A: The module accepts 24VDC pulse signals from field devices such as magnetic flowmeters, turbine meters, or optical encoders.
