Description

The Honeywell CC-PDIH01 is a high-density digital input module designed for process control and monitoring applications within the Experion Series-C I/O platform. It serves as a field interface for high-voltage discrete signals, accepting inputs from field contactors, switches, and interlocks to convey binary system states to the C300 controller.

Featuring 32 input channels, the CC-PDIH01 provides isolated sensing across various high-voltage AC and DC field levels depending on the selected Input Output Termination Assembly (IOTA). By utilizing a universal Input Output Module (IOM) hardware unit paired with specialized high-voltage IOTAs, the module streamlines system spare parts management while delivering galvanically isolated field signal processing for industrial plants.

Features

• High Channel Density: Provides 32 discrete input sensing channels within a compact Series-C module footprint.
• Flexible High-Voltage Support: Operates across 120 VAC/125 VDC or 240 VAC field signal levels using dedicated IOTAs.
• Standardized Hardware Assembly: Utilizes a single IOM architecture across different line voltages to minimize spare parts inventory.
• Galvanic Isolation: Features optical isolation providing 1500 VAC RMS or +/-1500 VDC isolation between field wiring and logic common.
• Flexible Redundancy Options: Supports non-redundant and redundant IOTA configurations for fault-tolerant automation architectures.
• Integrated Diagnostics: Incorporates internal hardware self-testing to maintain signal transmission integrity and reliable state reporting.
• Configurable Logic: Supports direct and reverse input state interpretation per channel to adapt to plant switch logic.

Applications

• High-Voltage Contact Monitoring: Sensing discrete status from motor control centers (MCC), circuit breakers, and auxiliary relay contacts operating at 120 VAC, 125 VDC, or 240 VAC.
• Plant Interlock Processing: Integrating hardwired field safety switches and process interlocks directly into C300 control strategies.
• Substation and Electrical Interface: Interfacing 125 VDC substation signals and utility status points into the Experion DCS.

Installation Guidelines

1. Confirm that field signal levels (120 VAC, 125 VDC, or 240 VAC) match the specific IOTA installed (e.g., CC-TDI110/120 or CC-TDI220/230).
2. Verify that power to field sensing circuits and the IOTA carrier bus is switched off before mounting hardware.
3. Securely mount the IOTA onto the cabinet carrier assembly.
4. Align the CC-PDIH01 module with the edge connectors on the IOTA and push firmly into place until seated.
5. Terminate high-voltage field wiring into the detachable screw terminal blocks on the IOTA, ensuring appropriate wire gauge and field grounding principles are followed.
6. Apply logic power to the IOTA carrier bus and field excitation voltage to test channel status indications.

Configuration Guidelines

1. Configure input channels within Experion Control Builder under the corresponding C300 controller I/O tree.
2. Select the channel direction (Direct or Reverse) according to field contact state specifications.
3. For redundant IOTA setups (e.g., CC-TDI120), assign the primary and secondary CC-PDIH01 modules to the same IOTA address slot to enable switchover functionality.
