6 Channels LOW Level Trigger 5V DC Input 240V 2A Output Omron SSR KF301 Terminals ⚡ MAINS VOLTAGE — This module switches 240V AC. Always isolate power before wiring. Use by qualified persons only. At a Glance 6 Channels 5V DC Control Input 240V 2A AC Output LOW Trigger Type Product Overview

This 6-channel solid state relay module uses Omron SSR components to provide reliable, silent switching of up to 240V 2A AC loads via low-voltage 5V DC control signals. Unlike mechanical relays, solid state relays have no moving parts — meaning faster switching, no audible click, longer service life, and no contact arcing.

The module operates on low level trigger logic — pulling a channel input to 0–2.5V (logic LOW) activates the relay; 3.3–5V (logic HIGH) turns it off. This makes it directly compatible with Arduino, Raspberry Pi, ESP8266/ESP32, and any 3.3V or 5V microcontroller. Each output is protected by a resistive fuse at 240V 2A. Blue KF301 screw terminals and 2.54mm header pins provide secure, tool-free AC load wiring.

• This module switches mains voltage (240V AC). Always isolate power before connecting or disconnecting AC wiring.
• Installation should only be performed by a qualified person familiar with mains voltage safety.
• Maximum AC load per channel is 240V / 2A. Do not exceed rated current — each channel is fuse protected.
• Ensure all AC wiring is fully insulated and enclosed. Never leave exposed mains terminals accessible.
• Always connect DC ground (DC−) to the microcontroller GND to ensure correct logic reference.
• Unconnected/floating CH pins may cause the relay to activate — always drive all pins to a defined state.
• Not suitable for inductive or motor loads without appropriate snubber or TVS protection.
