    Converter & Isolator

    ISC Din Rail Mount signal isolator is a 120/240VAC or 12-40VDC powered instrument which accepts an analogue input of mA or volts and converts it to an isolated 4-20mA or 0-10VDC output signal. A 24VDC loop supply for the direct connection of 2 wire transmitters is included.

    • Din rail or gear plate mounting
    • 24VDC loop supply
    • Power supply of 120/240VAC or 12 to 40VDC
    • Signal and power supply isolation
    • 0.1% linearity
    • Low cost - High performance
    • Low input impedance on mA signals
    • High input impedance on voltage signals
    • Special ranges of inputs and outputs are available on request

    The Innovec ISC is a single analogue input to single analogue output signal converter and isolator.

    The ISC accepts many standard and non-standard input signals and generates a 4-20mA or 0-10VDC output signal. Most other standard process current or voltage output signals can be provided on request.

    The ISC because of its versatile input to output combinations is a very flexible interface module. Low input impedance to current signals and high input impedance to voltage signals means the ISC can be inserted into existing systems without loss of performance.
