S1SD-1TI-1U PEPPERL FUCHS Temperature Signal Converter & Conditioner
The S1SD-1TI-1U PEPPERL FUCHS (Part No: S1SD-1TI-1U, Item No: 283204) is a highly compact, 1-channel DIP-switch configurable temperature signal conditioner manufactured by Pepperl+Fuchs. Designed for industrial process measurement, the S1SD-1TI-1U PEPPERL FUCHS converts temperature signals from Resistance Temperature Detectors (RTD Pt100/Pt1000), thermocouples (Types J, K, T, E, N, R, S, B), potentiometers, and millivolt inputs into isolated 0/4–20 mA or 0/1–5 V / 0–10 V DC process outputs.
Featuring an ultra-slim 6.2 mm housing width, the S1SD-1TI-1U PEPPERL FUCHS conserves valuable DIN-rail space inside control cabinets while delivering 3-port galvanic isolation (1.5 kV AC) between input, output, and power supply. Its DIP-switch configuration interface allows software-free commissioning, making it an essential component for temperature loops in factory automation panels, boiler skids, and marine telemetry systems.
Key Features of the S1SD-1TI-1U PEPPERL FUCHS
-
Universal Temperature Input Support: Compatible with 2-, 3-, and 4-wire RTDs (Pt100, Pt1000), thermocouples, millivolt sources, and potentiometer inputs.
-
Flexible Process Signal Outputs: Configurable output ranges including active current loops (0–20 mA, 4–20 mA) and DC voltage levels (0–5 V, 1–5 V, 0–10 V).
-
3-Port 1.5 kV Galvanic Isolation: Complete electrical isolation between input, output, and power supply prevents ground loops and electrical interference.
-
Ultra-Slim 6.2 mm Module Housing: High packing density allows mounting of multiple signal conditioners in space-restricted panels.
-
Easy DIP-Switch Configuration: On-device DIP switches enable fast range selection, cold-junction compensation, and sensor error behavior setup without software tools.
-
Power Rail Compatibility: Can be powered directly via wiring terminals or through the integrated 24V DC Power Rail bus system.
Primary Applications
-
Process Temperature Telemetry: Converting resistance and thermocouple measurements into standard 4-20 mA PLC analog inputs
-
Marine Telemetry & SCADA Systems: Isolating engine exhaust, cooling water, and lube oil temperature signals on shipboard control consoles
-
Factory Process Automation: Signal conditioning for industrial furnace heating control, thermal fluid loops, and HVAC systems
