Honeywell CC-PDIL01 Digital Input 24VDC Module

Product Introduction

The CC-PDIL01 is a 24VDC digital input module within the Honeywell Series C I/O family. This module accepts 24VDC signals as discrete inputs from field devices. Specifically, it provides 32 input channels per module for high-density discrete monitoring.

Furthermore, the module includes extensive internal diagnostics to protect data integrity. It detects and annunciates open field wires automatically. Besides, when a channel shows a seemingly valid PV but carries an open-wire diagnosis, the system flags the value as invalid. Therefore, incorrect control actions are prevented.

Additionally, the Honeywell CC-PDIL01 offers optional redundancy for critical applications. It supports internal or external field power selection, giving engineers flexible wiring options. Moreover, onboard excitation power removes the need for external marshalling power supplies.

Technical Specifications

The CC-PDIL01 provides 32 digital input channels. It accepts a DI power voltage range of 18 to 30 VDC. The ON sense threshold is 13 VDC minimum or 3 mA minimum. Meanwhile, the OFF sense threshold is 5 VDC maximum or 1.2 mA maximum.

Key electrical parameters include:

• Input Channels: 32

• Galvanic Isolation: 1500 VAC RMS or ±1500 VDC

• Isolation Technique: Optical (in IOM)

• DI Power Voltage Range: 18 to 30 VDC

• ON Sense: 13 VDC min / 3 mA min

• OFF Sense: 5 VDC max / 1.2 mA max

• Input Impedance: 4.2 kΩ

• Absolute Delay (input filter and isolation): 5 ms ±20%

• Field Resistance for Guaranteed ON: 300 Ω max @ 15VDC

• Field Resistance for Guaranteed OFF: 30 kΩ min @ 30VDC

Additionally, the module supports direct or reverse input indication. Galvanic isolation protects the controller side from field transients. Furthermore, the optical isolation technique resides in the IOM for reliable separation.

IOTA Compatibility

The Honeywell CC-PDIL01 works with several IOTA models for flexible installation. First, the CC-TDIL01 offers a non-redundant 9-inch terminal assembly. Next, the CC-TDIL11 and CC-GDIL11 provide redundant 12-inch options.

Moreover, the CC-GDIL21 delivers a non-redundant 6-inch form factor. Besides, the CC-GDIL01 supports redundant 12-inch expansion. Finally, the CC-SDXX01 serves as a GI-IS I/O expander at 12 inches.

Installation Guide

First, confirm that the IOTA is mounted and the system power is off. Next, seat the CC-PDIL01 module firmly into the IOM slot. After that, secure the module with its retaining screws.

For field wiring, connect discrete 24VDC signals to the IOTA terminals. The module detects open wires automatically during operation. Additionally, select internal or external field power according to your loop design. The onboard excitation power simplifies commissioning for dry contact inputs.

Finally, power up the system and verify channel states through the controller. The 5 ms input filter delay ensures stable readings. Moreover, self-diagnostics report channel faults and open-wire conditions.
