Product Description
The Yokogawa NFCP502-W05, also cataloged as the NFCP502 CPU Module, operates as a dedicated hardware component for real-time control execution and high-density network routing within Yokogawa FCN autonomous controller platforms. The unit coordinates SB bus communication while processing complex control loops via an onboard Intel Atom E3815 processor running at 1.46 GHz. It manages data throughput across 4 integrated Ethernet ports without introducing network transmission bottlenecks.

4-20 mA HART Loop Protocol and Channel Isolation
The Yokogawa NFCP502-W05 CPU module processes field data acquired from I/O modules connected across the duplex SB bus interface. The processor board incorporates galvanic logic isolation between the internal processing core and external communication ports, suppressing field noise and preventing ground loops. This isolation structure ensures uncorrupted data supervision for 4-20 mA HART loop protocol field instruments while maintaining uninterrupted execution of deterministic control routines.
Frequently Asked Questions
Q: How does the Yokogawa NFCP502-W05 CPU module protect critical SRAM data during main power loss?
A: The module incorporates a 1000 mAh graphite fluoride lithium battery to maintain power to the 2 MB ECC static RAM.
Q: What network speeds are supported by the 4 integrated Ethernet ports on the NFCP502-W05?
A: The RJ45 interfaces auto-negotiate across 10 Mbps, 100 Mbps, and 1000 Mbps (10BASE-T, 100BASE-TX, 1000BASE-T) communication standards.
Q: Is the NFCP502-W05 module rated for installation in hazardous explosive atmospheres?
A: No, option code 5 specifies a basic type enclosure lacking hazardous location explosion protection certification.
Field Installation Guidelines
- Isolate main power feeds to the FCN base rack before inserting or removing the CPU module.
- Align the NFCP502-W05 board edges with the designated CPU slot guide rails and push firmly until the rear SB bus connectors lock into place.
- Lower the CPU cover and engage the wire lock option through the designated hole to secure the assembly.
- Connect CAT5e or CAT6 Ethernet cables to the 4 RJ45 jacks, verifying that cable runs remain separated from high-voltage AC lines.
- Verify that the 5 VDC power supply voltage delivered to the backplane stays within the 5 VDC plus or minus 5% operating threshold.
