Signal isolator 24vdc netzteil 4 zu 20ma eingang signal splitter 3 ausgänge
This apparatus provides isolated power supply to the field two-wire, three-wire transmitter, and detects the current signal in a circuit meanwhile. It transmits the input current or voltage signal to isolated current or voltage signal in a circuit or two isolated circuits, and the input, output, and power supply are galvanically isolated from each other.
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, 1 in/4 out,2 in/2 out, with input/output magnetic isolation.
Signal splitters receive 4-20mA process current inputs and provide two identical isolated 4-20mA output signals. Each channel operates independently and is isolated from the others to prevent interaction between channels. Galvanic isolation eliminates ground loops, reduces noise, and blocks transient signals.
