The Pepperl+Fuchs S1SL-2AI-2C is a 2-channel passive isolator for analog current signals in industrial automation. It is loop-powered and transfers 0/4 ... 20 mA signals from the field side to the control side with galvanic isolation. With 0.1% accuracy, 6.2 mm ultra-slim housing, and ATEX/IECEx Zone 2 certification, this device provides a reliable, space-saving solution for isolating current signals in applications where an external power supply is unavailable or undesirable.

FAQs
Q1: What does "passive" mean for this isolator, and do I need an external power supply?
"Passive" means the device is loop-powered. It draws its power directly from the current loop (2.2 ... 30 V DC), so no additional 24 V DC power supply is required for the module itself.
Q2: What is the maximum load that the output can drive?
The analog current output (0/4 ... 20 mA) can drive a load (burden) of up to 600 Ω.
Q3: What types of signals can this isolator process?
It is designed specifically for standard analog current signals in the 0/4 ... 20 mA range from the field side. It cannot process voltage signals or temperature sensor inputs directly.
Q4: How much space does this module require on a DIN rail?
The module has an ultra-slim width of just 6.2 mm, making it highly space-efficient in control cabinets. It mounts on standard 35 mm DIN rails.
