2 channel 30A relay module with optocoupler isolation for robust automation and industrial system control. It can switch loads up to 30 A at 30 V or 250 V, making it suitable for a range of power applications. Key features and benefits Optocoupler isolation provides inputtooutput separation to improve noise immunity and protect control circuitry. Large power relays with LED indicators for each channel give clear status and reliable operation. Rated for up to 10 million operations, with a maximum switching frequency of up to 5 kHz, supporting substantial cycle life in sustained use. Compact size and mounting holes allow easy integration into existing enclosures, panels, or cabinets. Suitable for electrical engineers, hobbyists, and developers, offering a versatile platform for circuit modifications and electronic experiments. What it does Provides 2 independent relay channels for controlling power loads from a lowpower control signal. Supports loads up to 30 A at 30 V or 250 V, enabling control of devices such as lighting, motors, pumps, and other actuators through a controller or automation system. Each channel includes an LED indicator to show the active state and status at a glance. Compatibility, size and construction notes Designed to work with controllers, home systems, and industrial automation setups. Compact form factor with mounting holes to simplify installation in control panels and compact enclosures. The module emphasizes reliability and straightforward operation without unnecessary complexity. Performance and durability Relay life specification: up to 10 million operations. Switching performance: up to 5 kHz maximum switching frequency, suitable for many automation tasks that require fast response times. Use scenarios Home and building automation: connect to a microcontroller or controller module to manage lights, HVAC control signals, or other household devices from a central automation system. Industrial control and automation: integrate into control panels to manage actuators, fans, or process equipment with isolated control signals for improved reliability. Prototyping and experimentation: engineers and developers can modify and test circuits that require current switching without exposing the control circuitry to load voltages.
