Signal Isolator BSI139

BSI139 is a isolating transmitter designed for factory set input output combinations providing true 3-way galvanic isolation up to 2000V rms

Description

BSI139 is a isolating transmitter designed for factory set input output combinations providing true 3-way galvanic isolation up to 2000V rms.The power supply (ac or dc) is magnetically coupled to both the inputand the output circuit section separately, achieving power/input/output isolation. Input signals are transferred optically to the output stage. The standard Signal Isolator will accept DC voltage or current input signals directly (0.1V up to 100V, 1mA up to 100mA). BSI139 also accepts a wide variety of different sensors and signals using optional input conditioning card. Final calibration is trimmed using the front accessible ‘offs’ and ‘span’ 15-turn trim adjustments. The output signal level is indicated by a green LED on front of the module, giving a clear indication of module function, signal presence and loop condition for current outputs. Various power supply choices are available ranging from 240Vac down to 8Vdc. All supply models contain a dual output for power isolation. Reverse or direct action are factory configured. Special requirements for input/output response time variation can be accommodated by optional “customised response” or “output ramp” models. Surge protection for power supply and input is standard with all Series 100 modules
