Coupling Relays and Signal Converters

When standard controllers with their standard inputs/outputs reach their limits, coupling relays and interface converters come into their own. A wide selection of coupling relays and interface converters is available for the electrical isolation of I/Os and PLC inputs and outputs, signal amplification or reproduction as well as conversion to different voltage levels or signal forms. We offer the appropriate solution for all requirements.
