Description Specifications Omron 5V solid-state relay 240V/2A Fuse with Resistance 240V/2A Size: 55x33x25mm (length x width x height) Input Power Supply: 5VDC Input Control Signal Voltage: (0-2.5V, Low Level Status, Relay ON), (3-5V, High Level Status, Relay OFF) Module interface: Input: DC+: connect power positive (power supply according to relay voltage) DC-: connect power negative CH1: signal trigger end of relay module (low level trigger) CH2: signal trigger end of relay module (low level trigger) Meaning of high level and low level: High level trigger refers to a forward voltage between the signal trigger end (CH) and the power negative pole. The trigger is usually realized by connecting power positive end to the signal trigger end. When the trigger end has positive voltage or voltage reaches the trigger point, relay is closed. Low level trigger refers to a 0V between the signal trigger end and the power negative pole, or the voltage of the trigger end is lower than that of the power positive pole, which reaches the level of trigger point, the relay is closed. The trigger is usually realized by connecting power negative end to the signal trigger end.

Description: Learning infrared remote control switch, as its name implies, can let the single chip computer remember a key data of the remote controller, let it control the switch of the relay. By learning again, you can modify the stored key data. For example, this time you use the "8" key on the remote controller to study, after success, you can use "8" to control the key, power-down data is not lost, if If you want to use the button "9" as the control, you need to let the MCU learn again and make modifications. Module usage instructions: 1. Power supply, correct connection LED indicator lights on, 5 seconds later the module works normally, relay works at the same time! 2. With each press of the S1 button, the relay will switch its working state once, turn on or off, and the indicator light will be on or off at the same time! 3. After successful learning of infrared remote control, every time the successful learning remote controller is pressed (the learning method of remote control is below), the relay changes its working state once, turns on or off, and the indicator lights are on or off at the same time. Feature: Rated current: 10A Rated voltage: 5V Package Included: 1 x 1 Channel 5V Infrared Remote Control Relay Module 1 x Remote with battery
