NFDV151-P10/CCC01

The Yokogawa NFDV151-P10/CCC01 is a 32-channel digital input module designed to receive 24 V DC ON/OFF signals in Yokogawa FCN autonomous controller systems. It supports both status detection and push-button edge counting. The /CCC01 option specifies a connector cover for the MIL cable connection, providing a defined hardware configuration for field signal interfacing.

Functional Description

The module acquires discrete field signals and transfers their ON/OFF states to the controller for logic processing, status monitoring, and control operations. Its 32 input channels operate at a rated voltage of 24 V DC.

The module supports two input functions:

• Status input: Detects the ON/OFF state of connected field signals.
• Push-button input: Counts signal transitions (edges), allowing push-button operations to be registered as discrete events.

For status inputs, the specified response time is 8 ms or less. Push-button inputs have a minimum ON detection time of 20 ms and support a maximum ON/OFF cycle of 25 Hz.

Input Signal and Isolation Characteristics

The input threshold specifications define the voltage levels recognized as ON and OFF. Signals within the specified ON range are detected as active, while signals at or below the OFF threshold are recognized as inactive.

The module provides electrical isolation between the input signals and the system circuitry. Its specified withstand voltage is 2,000 V AC for one minute between the input signal and system, and 500 V AC for one minute between common groups. The latter specification applies to the 16-channel common grouping.

Connector Configuration

The /CCC01 option identifies a connector cover for the MIL cable connection. Yokogawa lists this accessory under the separate component designation NFCCC01. It should not be confused with the pressure-clamp terminal block options /B5S00 and /B5S10, which are different connection configurations.

When replacing this module, verify the existing MIL cable arrangement and connector-cover configuration before ordering.

Frequently Asked Questions

Q: Does the NFDV151-P10/CCC01 support push-button edge counting?

A: Yes. The NFDV151-P10 supports push-button edge counting in addition to standard ON/OFF status detection. Push-button operation has a minimum ON detection time of 20 ms and a maximum ON/OFF cycle of 25 Hz.

Q: What is the function of the CCC01 option?

A: CCC01 provides a connector cover for the MIL cable interface, identified by Yokogawa as NFCCC01. It is not a pressure-clamp terminal block or a surge absorber.

Q: Can all 32 channels be used for push-button inputs?

A: The module supports push-button edge counting on input channels 1 through 32. The remaining input specifications should be observed when selecting field signal devices and configuring the input circuits.
