The Honeywell CC-PPIX01 (original part number: 51410089-175) is a high-performance pulse input module (PIM) belonging to Honeywell's classic Experion PKS C300 controller system C-series (C-series) I/O hardware family. This hardware is primarily deployed in modern distributed control systems (DCS) as a high-precision signal acquisition card, designed specifically for connecting industrial flow meters and other measuring instruments in the factory field. It can acquire pulse or frequency signals generated in the process environment with high sensitivity.
The module's hardware architecture features extremely high data measurement accuracy, with 8 onboard single-channel or 4 dual-channel inputs supporting various configurations. According to official specifications, this module can monitor a frequency range of 0-100 kHz when performing single-channel acquisition and features high impedance, 1000 VDC optically isolated differential voltage input protection. The CC-PPIX01 module boasts exceptional readout accuracy of ±0.001% across a wide frequency range of 0.5 Hz to 100 kHz and features two dedicated low-latency solid-state relays for output channel cutoff, enabling simultaneous and accurate measurement of multi-dimensional data such as frequency (PV), cumulative value (AV), pulse width, and period.
In terms of application ecosystem and high-reliability design, the CC-PPIX01 module is fully compatible with Honeywell MeterSuite metering applications and strictly adheres to the ISO 6551 / API 5.5 (Class A Pulse Integrity) international dual-pulse fidelity standard. It is ideally suited for commodity settlement and storage monitoring in the oil and gas industry, where stability is paramount. The hardware is Class I Division 2 (Group A, B, C, D T4) and Zone 2 industrial explosion-proof certified, with a rated operating current of 735 mA @ 24 VDC. When deployed on-site, it can be flexibly configured as a channel-independent isolation or bus power supply mode, and supports the use of CC-TPIX11 input/output terminal blocks (IOTA) to form a 1:1 dual-machine hot standby redundant control chain, fully ensuring the continuous stability of the factory's core metering assets.
