Function
This Power Supply Module is a system component for the FieldConnex® Power Hub and can be plugged into the motherboard. It adapts current and voltage for the supply of fieldbus segments and field devices.
The combination of this power supply, selected motherboards and R2 Segment Protector provide outputs certified for explosion protection Entity Ex ic and Ex nL.
Reliability of communication is enhanced through galvanic isolation between segment and bulk power supply. Two LEDs indicate power and status. In redundant configuration two modules are connected in parallel via simple circuits ensuring seamless operation.
◾ Output: 21 ... 23 V/500 mA
◾ Voltage limitation for Entity ic and Ex nL
◾ With galvanic isolation
◾ Installation in Zone 2/Class I, Div. 2
◾ For FOUNDATION Fieldbus H1 and PROFIBUS PA
◾ Highest efficiency, lowest heat dissipation for highest packing
density
◾ Hot swappable in redundant configuration
◾ Module exchange without tools during operation
