      Description

      Our range of signal converters provide a convenient and reliable way of converting almost any input voltage, current or resistance to high current output.

      The High Current Output Signal Converter is a reduced function design to operate in the same way as our standard signal converters except with increased output current capability.

      Our design has several features which can be selected if required. The dual controller design provides isolation between input, power supply and output as well as output current and voltage measurements. The output relay can be used as an emergency switch or as a circuit isolator in electrochemical applications. The output can be configured to follow the analogue input or set directly using the serial communications.
