1-Channel DC 5V–24V Relay Controller, Max 4A Load Current

The C-1-72 is a single-channel relay controller designed for switching DC-powered electrical loads in commercial and industrial control applications. It accepts input voltages ranging from 5V to 24V and supports a maximum load current of less than 4A, making it suitable for low-current switching tasks in automation and lighting control systems. The unit is rated to operate across a temperature range of -20°C to 60°C, supporting use in environments subject to moderate thermal variation. Construction is plastic-housed.
