⚡ At a Glance
- • Switching Precision: Adjustable timing via high-level, low-level and passive switch control for tailored delays
- • Best for: Makers, electricians and small-scale automation projects controlling low-voltage or moderate AC loads
- • Not ideal for: High-current appliances or industrial machinery that demand more than 5A switching capacity
Works from 6–30V and accepts micro USB 5.0V power, with multiple trigger modes. Output handles up to 30V 5A DC or 220V 5A AC, with low standby current and a service life over 100,000 cycles.
Flexible power options – with a wide 6–30V input and micro USB 5V support
The module accepts supplies across 6–30V and can be powered via a micro USB 5.0V source. Static current is around 15mA while operating current reaches approximately 50mA.
Allows use with battery packs, bench supplies or standard USB chargers, making installation adaptable to available power sources.
Versatile triggering – thanks to high/low and passive switch inputs
Trigger inputs include a high-level trigger (3.0V–24V), a low-level trigger (0.0V–0.2V) and passive switch control. These ranges cover typical microcontroller outputs and mechanical switch wiring.
Works straight from MCU outputs or simple switches without extra signal conversion, simplifying integration into automation projects.
Reliable switching for small loads – with a 5A relay output
Relay contacts are rated to control equipment within 30V 5A DC or 220V 5A AC, and the module is specified for more than 100,000 operations. Operating temperature spans -40°C to 85°C for varied environments.
Suitable for lamps, small motors and auxiliary circuits within the 5A limit, and built to withstand frequent switching cycles.
