ISCX3 Signal Converters

ISCX3 Din Rail Mount Signal Splitter and Isolator is a 85 to 265VAC powered instrument which accepts an analogue input of mA or volts and converts it to three independent isolated 4-20mA or 0-10VDC output signal. A 24VDC loop supply for the direct connection of 2 wire transmitters is included.

The ISCX3 is a single analogue input to three independent analogue output signals

The ISCX3 accepts many standard and non-standard input signals and generates a 4-2-mA or 0-10VDc output signal. Most other standard process signals are available on request.

The ISCX3 because of its input to output combinations is a very versatile interface module. The ISCX3 can be inserted into existing systems without loss of performance
