Honeywell CC-PDIH01 High Voltage DI Module

Product Introduction

The CC-PDIH01 delivers high-voltage discrete input processing for Honeywell Experion PKS Series C control systems. Specifically, this input/output module accepts 120VAC, 125VDC or 250VAC field signals as discrete inputs. Notably, the same IOM works with different IOTA bases for the 120VAC/125VDC and 250VAC ranges. This shared-module design reduces the number of spare parts required for Series C system maintenance. Furthermore, extensive internal diagnostics continuously verify data integrity across all 32 input channels.

Technical Specifications

The CC-PDIH01 combines high channel density with robust electrical isolation. Its specifications support direct interface to industrial field voltages without external signal conditioning.

Input and Isolation Ratings

The module provides 32 input channels with galvanic isolation between field and logic common rated at 1500 VAC RMS or ±1500 VDC. Isolation uses optical coupling technology, which prevents field transients from reaching the controller logic. Additionally, the module supports input direct/reverse configuration for flexible signal polarity handling.

IOTA Compatibility

The CC-PDIH01 pairs with several termination assemblies depending on voltage class. For 120VAC applications, engineers select the CC-TDI110 (non-redundant, 9-inch) or CC-TDI120 (redundant, 12-inch). The CC-TDI151 (non-redundant, 12-inch) serves proximity sensor inputs at 120VAC. Meanwhile, 240VAC applications use the CC-TDI220 (non-redundant, 9-inch) or CC-TDI230 (redundant, 12-inch). Optional redundancy is available on all IOTA models except the CC-TDI151.

Voltage and Current Characteristics

Nominal voltage depends on the paired IOTA. The CC-TDI110 and CC-TDI120 accept 120VAC or 125VDC with a power range of 90-132 VAC RMS or 100-138 VDC. The CC-TDI220 and CC-TDI230 accept 240VAC across 180-264 VAC RMS. Sense current in the ON condition measures 1.0 mA for 120VAC and 1.2 mA for 125VDC. OFF-state sense current stays below 0.32 mA.

Timing and Frequency Response

Pick-up voltage reaches 90 VAC RMS for 120VAC inputs and 100 VDC for 125VDC inputs. Drop-out voltage remains below 25 VAC RMS or 25 VDC. Absolute delay across the input filter and isolation stage measures 25 ms maximum for AC inputs and 10 ms maximum for 125VDC. The frequency range spans 47-63 Hz for all AC configurations.

Mechanical and Environmental Parameters

The CC-PDIH01 installs in Series C IOTA slots sized at 9 or 12 inches depending on the selected termination base. The module operates within the standard Series C cabinet environment alongside its paired IOTA. Optical isolation technology separates field wiring from sensitive logic circuits. The module design supports hot replacement when paired with detachable-terminal IOTAs. Redundant configurations allow module swap without process interruption on supported IOTA models.

Installation Guide

Installation starts with selecting the correct IOTA for the field voltage class. First, mount the chosen termination assembly, such as the CC-TDI120 for redundant 120VAC service. Next, wire the field discrete signals to the IOTA terminals according to the channel assignments.

Insert the CC-PDIH01 module into the IOTA slot and confirm full seating. Meanwhile, set the input direct/reverse configuration to match the field signal polarity. After power is applied, verify that internal diagnostics report no channel faults. Finally, test pick-up and drop-out thresholds on representative channels before commissioning the loop.

FAQ

Q1: What field voltages does the CC-PDIH01 accept?
A1: The CC-PDIH01 accepts 120VAC, 125VDC or 250VAC signals depending on the paired IOTA base.

Q2: How many input channels does this module provide?
A2: The module offers 32 input channels with optical isolation.

Q3: Which IOTA models support redundant operation?
A3: The CC-TDI120 and CC-TDI230 support redundancy. The CC-TDI151 proximity model does not offer redundancy.

Q4: What is the isolation rating of the CC-PDIH01?
A4: Galvanic isolation between field and logic common reaches 1500 VAC RMS or ±1500 VDC using optical coupling.

Q5: Why does one IOM serve both 120VAC and 250VAC ranges?
A5: Honeywell designed the CC-PDIH01 to share one IOM across voltage classes with different IOTAs. This approach reduces spare parts inventory for Series C maintenance.
