hiBCTR 4CH 24V Relay Module OPTO-Isolated - High/Low Level Trigger 10A 250VAC for PLC/Arduino/Raspberry Pi Industrial Control
Product Description
hiBCTR 4CH 24V Relay Module OPTO-Isolated - High/Low Level Trigger 10A 250VAC for PLC/Arduino/Raspberry Pi Industrial Control
- 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.
