S109S

Galvanic isolation for 4-20 mA current loop
S109S is a signal converter and power supply with galvanic separation for current loop 0-20 mA and 4-20 mA. It allows to feed both input and output loop with 24 Vdc voltage. S109S is available with main supply 115 Vac and 230 Vac. Insulating voltage between input and output circuits is about 2.000 Vdc, high precision and linearity are guarantee thanks to a linear optoisolator to separate signals. S109S gets a rail enclosure in 2 modules DIN, autoextinguishing noryl; to be placed on 35 mm bar (DIN 46277). It’s largely used in measurement signals insulation between transducers in field and acquisition instrumentation.
