Product Overview
Pepperl+Fuchs RD0-FB-Ex4 is a FieldConnex fieldbus barrier for DIN rail mounting and hazardous area fieldbus applications.
This model is suitable for customers searching for Pepperl+Fuchs RD0-FB-Ex4, FieldConnex fieldbus barrier, FOUNDATION Fieldbus H1 barrier, PROFIBUS PA barrier, or intrinsic safety device coupler quotation support.
Main Features
4 outputs with Ex ia IIC protection.
FieldBarrier installation in Zone 1 / Div. 2.
Supports instruments in Zone 0 to Zone 1 / Div. 1.
Short-circuit current limitation is provided for each output.
Designed for FOUNDATION Fieldbus H1 and PROFIBUS PA systems.
Power, communication and error LEDs help simplify troubleshooting.
Supports FISCO and Entity concepts, integrated cable tie-downs and multiple grounding methods.
Function
The RD0-FB-Ex4 FieldBarrier connects up to 4 field instruments with intrinsic safety and short-circuit current limitation at each spur output.
This design helps maintain stable segment operation during faults or hot work at the spur.
High power on the trunk enables longer cable lengths and higher device count in hazardous area fieldbus installations.
The integrated fieldbus terminator is selectable and designed for high availability.
Fieldbus Connection
Main cable trunk connection includes Trunk IN and Trunk OUT terminals.
Trunk rated voltage: 32 to 16 V DC.
Rated current without load: 31 mA to 26 mA.
Rated current at 20 mA load per input: 77 mA to 115 mA.
Rated current with short circuit on all outputs: 135 mA to 241 mA.
Voltage drop from trunk IN to trunk OUT: maximum 100 mV.
Outputs
Number of devices per output: 1.
Output 1: terminals 10+, 11-, 12S shield.
Output 2: terminals 13+, 14-, 15S shield.
Output 3: terminals 16+, 17-, 18S shield.
Output 4: terminals 19+, 20-, 21S shield.
Output rated voltage: 10 to 13 V.
Output rated current: maximum 43 mA.
Short-circuit current: 50 mA.
Status Indication
Fieldbus voltage LED: green, on when bus voltage is present.
