This prevents voltage spikes or noise on the load side from damaging the sensitive control electronics.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this module compatible with Arduino and Raspberry Pi?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The 3.2V–5V input range is directly compatible with standard 3.3V and 5V logic levels used by Arduino, Raspberry Pi, ESP8266, ESP32, STM32, and most common MCU development boards. No additional components are required for basic signal isolation.\u003c\/p\u003e\n\u003ch4\u003eQ: Can this module handle 12V or 24V input signals from a PLC?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. This module supports both 3.2V–5V and 12V–24V input ranges, making it well-suited for industrial PLC applications that operate at higher logic voltages.\u003c\/p\u003e\n\u003ch4\u003eQ: Does the package always include a cable?\u003c\/h4\u003e\n\u003cp\u003eA: The module is available in two variants — the module only, or the module bundled with a connecting cable.
