TERMINAL PLATE F860-CA redundant fieldbus power for Honeywell Experion “Series C” 4-link FIM HONEYWELL

Description

Overview

Essential details：TERMINAL PLATE F860-CA redundant fieldbus power for Honeywell Experion “Series C” 4-link FIM HONEYWELL

The F860 is designed to provide redundant power for eight Foundation fieldbus™ H1 segments when used with Honeywell Experion “Series C” Fieldbus Interface Modules (FIMs). The module carrier complies with the mechanical and electrical requirements of 11.6 inch I/O Termination Assemblies (IOTAs), for direct fitting into Honeywell mounting channel.
Power for the fieldbus segments is provided by two power modules – F801s or F802s – operating in a redundant configuration. Failure alarms, galvanic isolation, power conditioning and segment termination are incorporated into each F80x module. In simplex applications, a single F80x module may be used. Termination of the fieldbus segments is automatically maintained when single or redundant F80x modules are fitted.
For extreme reliability, the F860 IOTA is passive and only provides interconnections between the power modules and the external connections.
The IOTA has two multi-pin connectors, each of which is connected to a FIM IOTA by mean of a standard system cable. Different lengths are available, to accommodate mounting of the F860 and its respective FIM IOTAs in various locations within a Series C I/O cabinet. Field wiring is connected at the FIM IOTA.

Each F80x module provides galvanic isolation between the 24V DC input power and the fieldbus segments, as recommended by the IEC61158-2 fieldbus standard and the Fieldbus Foundation™ FF-831 validation test for power conditioners.
There is galvanic isolation between the fieldbus segments, thereby preventing segment failure in the event of ground faults in the field wiring.
Each F80x module has indicator LEDs to show both its status and that of the eight segments under power. In normal operation, each green ‘Segment’ LED is lit, showing that the segment is powered. If a segment is shorted, this LED is extinguished, and the red ‘Alarm’ LED is lit. An alarm is also triggered by faults inside the F80x modules, or by the loss of 24V DC power to either module. In the alarm condition, fault inputs for segments 1–8  are alerted automatically via dedicated signal lines in the interconnecting cable to the FIM IOTAs. Separate digital input modules are not needed to detect alarms.
