Subminiature Electromagnetic and Solid State Modules

Subminiature electromagnetic relays are used for PLC systems and industrial automation applications, panel builders, equipment builders and other applications that require a high switching capability in a small space. The Altech slim line interface relays can be used as a universal interface between the controller and the actuator to switch loads between 1 mA and 6A. They are available with electromechanical contacts or solid state configuration. Installation time is greatly reduced when a pre-assembled relays and sockets combination is used. Replacement relays and sockets are available from stock. Additional accessories include colored coded jumpers, spacers and markers (unmarked or marked based on the customer specification) for identification purposes.

  • Standard SPDT contact configuration
  • Rated load current
  • Space-saving 6.2 mm width
  • 6A / 250V AC or 0.05A / 30V AC gold plated) rating
  • Only 85 mm in height from DIN rail
  • 6A / 24V DC or 0.05A / 36V DC gold plated) rating
  • DC Coil voltages from 5VDC to 110V DC
  • 4A max for Solid state relays
  • AC coil voltages from 6VAC to 240V AC 50/60 Hz
  • Silver Tin Oxide (AgSnO2) cadmium free contact material
  • Pre-assembled relay and DIN mount socket
  • Gold plated contact (AgSnO2/Au 3µm) available
  • Screw clamp or Spring clamp terminals • UL recognized
  • Universal AC/DC socket with built-in surge suppression and green LED

Industrial Electromagnetic Relays

Relays for Photovoltaic

The Altech photovoltaic relays are suitable to be integrated in the solar converter to switch the DC voltage and current generated by the solar panels supplying the generated electricity to the electrical network. This requires an interface between the solar converter and the power grid. The circuit isolation gap between the converter and the power grid must have a contact gap of ≥ 1.5mm (according to safety standard DIN VDE 0126-1-1). Altech offers two different relays to meet this requirement.

  • Standard DPST (2 NO) contact configuration
  • Contact gap >1.75 mm ; Holding power 1W
  • DC Coil voltages from 5VDC to 110V DC
  • Silver Tin Oxide (AgSnO2) cadmium free contact material
  • Rated load current • Compact size, PCB mounting
  • 35A / 250V AC or 48A / 250V AC
  • UL recognized
  • 35A / 24V DC or 48A / 24V DC
  • ROHS2 and REACH compliance
