Special Features

  • ​​Industrial-Grade Switching​​: 4x 10A/250VAC or 10A/30VDC relays (NO/NC/COM terminals) with silver alloy contacts for 100,000+ cycles.
  • Dual Trigger Modes​​: Jumper-selectable high/low level control (5mA trigger current) compatible with 3.3V/5V/24V PLCs & microcontrollers.
  • Enhanced Safety​​: SMD optocoupler isolation (3,750Vrms) prevents back-EMF damage; fault-tolerant design ignores broken control wires.
  • Robust Construction​​: Flame-retardant PCB with 4x M2.5 mounting holes (67×44.5mm pitch), screw terminals, and LED status indicators (power + per channel).
  • Plug & Play Integration​​: 24VDC powered (18-30V range) with pre-soldered headers for Arduino/Raspberry Pi projects.
