- Indicator LEDs show relay output status at a glance. - Optocoupled 8-channel design uses transistors, diodes and optocouplers to switch higher loads safely with low input power. Generously sized relays provide reliable operation over many switching cycles. - Heavy-duty relays with switching capacity: AC up to 250 V at 10 A; DC up to 30 V at 10 A. - Direct compatibility: can control Raspberry Pi, Arduino, AVR, PIC, 8051, DSP, ARM, MSP430, TTL logic, and other single-chip microcomputers. - Robust construction and components for dependable performance in continuous or prototype use. - Use scenarios: - Home automation: switch lights, fans, or pumps from a microcontroller with isolation for safety. - Prototyping and test benches: automate sensors and actuators, run sequences, and validate hardware designs. - Educational projects: teach control logic, relay operation, and isolated switching in labs or classrooms.
