The APCS SI239 Signal Isolator v2 converts DC signals with 2-wire/3-wire outputs, 2000Vdc input, and true RMS option. It offers 2000Vrms isolation, span/zero adjustments, and features like adder/subtractor for versatile signal conversion.
The APCS SI239 is a DIN-rail signal isolator and converter that turns DC current or voltage inputs, up to 2000 V DC or 10 A DC, into a standard isolated DC signal. It provides 2000 Vrms isolation and can power 2-wire or 3-wire output loops, with a true RMS option for AC signals.
Zero and span are adjusted from the front, and adder/subtractor and min/max select options allow two signals to be combined or compared. It is widely used to interface high-voltage or high-current signals with PLCs, prevent earth loops, protect instruments and filter electrical noise. See the SI239 datasheet.
