Yokogawa NFCP501-S05 CPU Module

Configured for critical industrial control applications, the Yokogawa NFCP501-S05, also cataloged as the NFCP501-S05 CPU Module, operates as a dedicated processing unit within automation platforms. The module integrates an Intel Atom E3815 processor with onboard memory and communication interfaces to manage real-time operations across energy, manufacturing, and oil and gas systems.

Hardware Specifications

Channel Isolation and Communication Protocols

The Yokogawa NFCP501-S05 features comprehensive communication interfaces supported by galvanic isolation across signal paths to prevent field ground loops from interfering with internal processing units. The module includes two RJ45 Ethernet ports for fast network connectivity alongside an RS-232-C serial port supporting full and half-duplex modes with baud rates from 0.3 kbps to 115.2 kbps. This design preserves channel isolation and data integrity for 4-20 mA HART loop protocol supervision and field device management.

Frequently Asked Questions

Q: What type of processor powers the Yokogawa NFCP501-S05 module?

Q: How is memory protected against power loss on the NFCP501 CPU module?

A: The unit incorporates a 1000 mAh graphite fluoride lithium battery to back up the 2 MB static RAM and prevent data loss during power interruptions.

Q: What external storage formats are supported by the module?

A: The hardware supports Class 10 SDHC cards ranging from 4 to 32 GB through its dedicated external storage slot.

Field Installation Guidelines

1. Power down the control rack completely before installing or removing the NFCP501-S05 CPU module.
2. Align the module card edges with the designated rack guide rails and push firmly until the backplane connector seats securely.
3. Secure the protective CPU cover and engage the wire lock option to ensure a safe physical installation.
4. Connect network cables to the RJ45 Ethernet ports and attach legacy serial devices to the 9-pin D-sub RS-232-C port.
5. Verify that the 5 V DC power supply rails fall within the specified plus or minus 5% tolerance range prior to system startup.
