Views: 270
Applications: Signal isolator utilized in automated control systems is a kind of instrument for transformation & distribution, isolation, transmission, operation of a variety of industrial signal, it can also be used with all kinds of industrial sensor to retrieve parameters of signals, isolation, transformation and transmission for remote monitoring local data collection.

SPE-7100 Series temperature signal  isolate

   Voltage/Current Isolator will isolate DC voltage or current signals, convert them into required signals and transmit to other instrument. It can be used together with modular instrumentation and DCS, PLC and other systems, to offer signal isolation, signal conversion, signal distribution, signal processing and other functions to field instrument, thereby enhancing the immunity of automatic control system in the industrial production process, and ensuring system stability and reliability. This product has many varieties, such as 1 in/1 out, 1 in/2 out, 2 in/2 out, with input/output magnetic isolation
