Technical Specifications

I/O Configuration and Capacity

• Total I/O points: CC-PUIO01 offers exactly 24 physical connection points.

• Digital inputs: Accepts 24V DC signals from field devices like switches.

• Digital outputs: Provides 24V DC signals to actuators or relays.

• Analog inputs: Measures 4-20 mA signals from transmitters or sensors.

• Analog outputs: Sends 4-20 mA signals to positioners or final control elements.

• Mixed operation: You can assign each channel freely as input or output. As a result, this maximizes your flexibility in the field.

HART Communication Support

• Built-in HART: The CC-PUIO01 supports HART protocol on analog channels.

• Benefits: You get both primary process variable and secondary device data.

• Use case: For example, you can configure smart transmitters or perform remote diagnostics easily.

Protection Features

• Electronic short circuit protection: Yes, each output channel has this feature.

• Result: The module prevents damage from wiring mistakes or overloads.

• Reliability: Accordingly, this protection increases uptime in your control system.

Environmental Tolerance

• Temperature range: Operates from -40°C to +70°C ambient.

• Humidity tolerance: Works at 5% to 95% non-condensing RH.

• EMI immunity: Designed for high noise industrial environments.

• Vibration resistance: Suitable for panel mounting near machinery.

Diagnostic and Status Indication

• LED indicators: Shows power, status, and channel health.

• Diagnostic data: The module reports open wire and short circuit faults.

• Redundancy ready: Supports redundant I/O configurations for critical processes.

Installation Guide

Follow these steps for proper installation of the CC-PUIO01.

1. Remove power from the chassis before inserting the module.

2. Align the module with the guides inside the rack slot.

3. Push firmly until the locking mechanism clicks into place.

4. Secure the wiring using the supplied terminal blocks.

5. Connect field devices as per the Honeywell pinout diagram.

6. Label each wire clearly for future maintenance work.

7. Restore power and observe the status LEDs for normal operation.

Always use copper conductors rated for 75°C minimum. Tighten terminal screws to 0.5 Nm.

Frequently Asked Questions (FAQ)

1. Can I mix analog and digital channels on the same CC-PUIO01?
Yes, you can assign any of the 24 points as analog input, analog output, digital input, or digital output. Consequently, this design reduces your inventory needs.

2. Does the CC-PUIO01 work without HART configuration?
Yes, the module operates normally as a standard analog I/O device. In fact, HART communication is an optional feature you enable via software.

3. How do I know if the electronic short circuit protection activated?
The module’s status LED will blink red for that specific channel. Likewise, the controller also receives a fault diagnostic message.

4. What wire gauge is suitable for the terminal block?
Use wire sizes from 0.2 mm² to 1.5 mm² (24 AWG to 16 AWG). Strip insulation to 7 mm before insertion.

5. Can I hot-swap the CC-PUIO01 in a running system?
No, you must remove power from the rack before installation or removal. Otherwise, hot-swapping may damage the module or backplane.
