RKC Instrument reliable and accurate process and temperature controllers from Japan
industry 4.0 ready

The range consists of:

  • solid state relays (SSR)
  • thyristor units
  • with or without built- in or external super-fast fuses
  • heater-break alarm (for detection of broken or short-circuit on heating element)
  • current limiter for inductive and MoSi2 loads
  • industry 4.0 ready systems with MODBUS RTU interface

Suited for many types of applications and heating elements:

  • resistive loads (resistance not dependent on temperature)
  • inductive loads (i.e. primary side of transformer)
  • molybdenum (MoSi2) elements (i.e. Kanthal super)
  • silicon carbide (SiC) elements

Our specialists can advise you which unit is best suited for your specific application.

Which control method to select for your heating element?

  • 2 phase versus 3 phase control?
  • zero cross versus phase-angle control?

SSL series

A DIN-rail mount compact and low-cost series of solid state relays of 15 and 25A, 60-280Vac, designed to replace electromechanical contactors (normal relays) for 1  phase resistive loads.

SSNP/SSNZ series

A DIN-rail mount compact series thyristors of 15 and 25A, 100-240Vac, for 1  phase resistive loads. Benefit of a thyristor with regard to a solid state relay is, that this unit enables you to modulate the power to the load with a 4-20mA control signal from the temperature controller.
