Yokogawa F3SP28-3S Sequence CPU Module

Hardware Specifications

Process Loop Integration and HART Protocol Support

Designed for integration within Yokogawa process automation infrastructures, the module facilitates seamless data exchange across digital, analog, and communication loops. Furthermore, the unit supports 4-20 mA HART loop protocol routing configurations, enabling simultaneous process variable transmission and digital diagnostic polling from smart field instruments. Through precise channel-to-channel isolation management and cold junction compensation handling on associated I/O modules, the controller preserves signal integrity across extended distributed control network loops. Additionally, the system executes firmware flash compatibility updates via WideField3 programming environments, ensuring straightforward maintenance adjustments during operational life cycles.

Frequently Asked Questions

Q: What programming software packages are fully compatible with this CPU module?

A: The module supports WideField, WideField2, and WideField3 software environments for configuration, program compilation, and debugging tasks.

Q: Does this hardware component support hot-swapping on active backplanes?

A: No, base unit power must be fully de-energized prior to inserting or extracting the CPU module to prevent backplane bus corruption or electrical damage to internal components.

Q: How is system power supplied to the F3SP28-3S module?

A: The unit receives regulated operating power internally through the base unit backplane connection operating on a 24 VDC system voltage rail.

Field Installation Guidelines

Mount the F3SP28-3S module securely into the designated CPU slot of the Yokogawa FA-M3 base unit, ensuring proper mechanical latch engagement. Verify that enclosure ambient temperatures remain within the specified range of -20 deg C to +60 deg C with relative humidity levels between 5% and 95% non-condensing. Route all communication and power cables away from high-voltage AC lines to minimize electromagnetic interference. Ground the base unit chassis in accordance with local industrial electrical codes before applying system power.
