FIELDBUS SEGMENT PROTECTORS Junction module provides a ‘star’ connection for end instruments to connect to the bus. Short circuit protection prevents an instrument failure from disrupting the entire segment.

Device Fault Short Circuit General Layout – FF H1 Segment Control Cabinet Bulk power supply Host with FF cards Device Fault Short Circuit FF power supply / conditioner T Terminator Transient suppressor Field If you do NOT use Device Couplers with short circuit protection…. The entire fieldbus can go down.. Terminator T FF devices

General Layout – FF H1 Segment Control Cabinet Bulk power supply Device Fault Example Host with FF cards 6 devices at 15 mA each FF power supply / conditioner Segment protector circuitry limits short T 131 mA 90 mA Terminator 56 mA 15 mA Transient suppressor Field This is how the Short Circuit protection works… notice the meter readings. Device Couplers do not allow the circuit to be completely shorted…therefore remaining devices continue to operate. T Terminator FF devices

Device Couplers Short circuit protection: 15-60mA, fixed / switchable 2,4,6,8,10,12-spur versions A device can be removed without disrupting communication Terminator: built-in, switchable, external, or automatic LED indication of status Access points for handheld communicators Entire approvals range available in most cases… Zone 0-1-2, Div 1-2 Compatible with FISCO, FNICO, or Entity Pluggable screw terminals IP20 DIN mount and IP67 with enclosure options

FOUNDATION FIELDBUS POWER SUPPLIES FF Power supplies are used to provide power to each segment while allowing for isolation between segments. An integrated filter prevents the power supply from eliminating, or sinking, the superimposed data on the network.

Fieldbus Power Supplies Single channel isolated and multi channel redundant versions 1,2,4,8-segment variations Alarm contact for indication of failures Advanced bus diagnostics Built-in terminators Input 18-30Vdc Output 14-30Vdc @ 350-1A load Non isolated versions also available (“power conditioner”) FF-831
