SIL 2 RTD/Resistance Isolating Repeater


The single channel Isolating Repeater D5072S-087 accepts a 2-3-4 wire resistance/RTD or 2-wire transmitting potentiometer sensor, up to 400 Ω, located in Hazardous Area, and repeats the resistance, with isolation, to Safe Area, suitable for applications requiring SIL 2 level (according to IEC 61511) in safety related systems for high risk industries. Mounting on standard DIN-Rail, with or without Power Bus in Safe Area or in Zone 2. Choice between 2, 3 or 4 wires Input is accomplished via dedicated DIP Switch. Among all possible sensors, typical are:
• IEC: Pt50, Pt100
• ANSI 0.3916: Pt100
• DIN43760: Ni100, Ni120
• GOST6651 russian standard: Pt46, Pt50, Pt100 ,Cu50, Cu53, Cu100
• Cu9.035 (or Cu10)


• Input from Zone 0 (Zone 20) / Division 1, installation in Zone 2 / Division 2.
• 2 or 3 or 4 wire resistance/RTD or 2 wire transmitting potentiometer Input Signal.
• Burnout Fault detection.
• Three port isolation, Input/Output/Supply.
• EMC Compatibility to EN61000-6-2, EN61000-6-4, EN61326-1, EN61326-3-1 for safety systems.
• Simplified installation using standard DIN-Rail and plug-in terminal blocks, with or without Power Bus.
• 250 Vrms (Um) max. voltage allowed to the instruments associated with the barrier.
