Features:

  • Connection Between Field I/O Devices and Honeywell Control System Backplane
  • Integrates Signal Termination with Organized Wiring Distribution
  • Works Together with C300 Controllers and Series 8 I/O Modules
The F860-CA operates as the IOTA (Input/Output Termination Assembly) module in a Honeywell control system rack, providing reliable physical termination and signal distribution for all connected I/O channels. It continuously routes field signals from sensors, transmitters, and actuators to the corresponding I/O cards through the rack backplane, ensuring accurate data transmission for steady-state operation of the entire control system. Seamless signal integration is standard with the F860-CA, and using it in conjunction with redundant I/O configurations allows continued operation in the event of a single channel or module failure. The F860-CA has improved wiring organization and maintenance accessibility over previous termination designs, while incorporating standardized connection capabilities within the Honeywell Experion PKS architecture.

The F860-CA provides essential termination functions common to the entire I/O subsystem, and is a critical component of the control signal path, directly affecting the proper, normal operation of the overall monitoring and control system. One F860-CA is required per I/O card slot depending on the specific I/O type being terminated. The F860-CA occupies a dedicated slot position adjacent to its corresponding I/O module and is always installed in the IOTA slot position (the designated termination assembly location).

For redundant I/O applications, the Honeywell system requires a second F860-CA termination module installed alongside the redundant I/O card. In addition to standard single-channel operation, the redundant configuration also performs automatic signal failover. The F860-CA dual termination configuration executes failover using the internal circuitry specified in the I/O module options. Using this method, the redundant signal system continually monitors the health of both I/O paths. If the system detects that the primary I/O channel is no longer providing stable signal output (outside configured tolerance levels), it will automatically transfer the signal path to the secondary channel and generate a system alarm notification.

The F860-CA Honeywell IOTA Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Honeywell F860-CA is a specialized Fieldbus I/O Termination Assembly (IOTA) module specifically designed to support the Experion PKS Series C Fieldbus Interface Modules (FIMs). It functions as a critical mounting and interconnection platform for redundant fieldbus power modules, such as the F801 or F802, providing the physical link between the control system and external field devices. By integrating communication and power distribution into a single passive assembly, the F860-CA streamlines the hardware footprint within the control cabinet while ensuring robust connectivity for up to eight FOUNDATION™ fieldbus H1 segments.

In industrial automation environments, the F860-CA is engineered to handle the challenge of maintaining continuous segment operation during power supply failures or maintenance. This F860-CA module specifically addresses the risk of total segment downtime by facilitating an N+1 redundant power architecture. It solves the problem of critical signal loss by allowing the hot-swapping of power modules without interrupting the communication or power flow to field instruments. This ensures that even if one power source fails, the F860-CA maintains the integrity of the fieldbus loop, preventing costly process shutdowns in high-stakes industries like oil and gas or chemical processing.

The technical design of the F860-CA also resolves complex wiring and diagnostic hurdles inherent in large-scale fieldbus deployments. Traditionally, managing the physical layer of multiple fieldbus segments requires extensive manual wiring and external diagnostic tools; however, the F860-CA provides dedicated ports for integrated physical layer diagnostics (such as the F809F module). This allows the F860-CA to solve the problem of "blind" network management by giving operators real-time visibility into segment noise, voltage drops, and jitter. By centralizing these functions, the F860-CA simplifies long-term maintenance and significantly reduces the mean time to repair (MTTR) for the fieldbus infrastructure.
