NFDV551-P10/CCC01

The Yokogawa NFDV551-P10/CCC01 is a 32-channel digital output module for the STARDOM FCN autonomous controller platform. It provides isolated 24 V DC transistor outputs for switching external field devices. The module uses current-sink output circuits and supports individual channel status indication. The /CCC01 option specifies a connector cover for MIL cable connections.

Digital Output Function

The NFDV551 provides 32 discrete output channels for transmitting ON/OFF control signals from the controller to external field circuits. Its current-sink output arrangement switches the connected load by controlling the current path to the common negative side.

Each output channel supports a specified load voltage of 24 V DC and a 50 mA load condition. The maximum load current is 100 mA per channel at 26.4 V. These ratings should be checked against the connected device requirements before wiring.

Channel Monitoring and Output Behavior

Individual green LED indicators display the ON/OFF state of channels 1 through 32. This provides a local indication for checking output activity during commissioning and maintenance.

The module also supports three output fallback selections: HOLD retains the current output states, OFF resets all channels to OFF, and NO performs no fallback action. The selected fallback behavior applies commonly to all output channels rather than independently to each channel.

Ordering Code Identification

The ordering configuration can be identified from Yokogawa's published model and suffix code information:

Code	Description
NFDV551	32-channel, 24 V DC isolated Digital Output Module
-P	Standard type
1	With status display
0	Basic type
/CCC01	Connector cover for MIL cable, model NFCCC01

The /CCC01 option identifies the connector cover accessory. It should not be confused with a pressure clamp terminal block, which is a separate connection option.

Frequently Asked Questions

Q: How many digital output channels does the NFDV551-P10/CCC01 provide?

A: It provides 32 isolated digital output channels. Each channel is designed for 24 V DC field switching, with a specified load condition of 50 mA.

Q: What is the function of the /CCC01 suffix?

A: /CCC01 specifies the MIL cable connector cover NFCCC01. It is a connector accessory designation, not an additional output channel or a different electrical output configuration.

Q: Can the module directly drive a DC relay?

A: The module can drive DC loads within its output ratings. Yokogawa specifies that a diode should be connected when driving a DC relay. The relay coil current and voltage must also remain within the module's applicable load limits.
