4路5V 低電平觸發固態繼電器模組 SSR 固態繼電器 帶保險絲
4路5V低電平觸發固態繼電器模組, SSR 固態繼電器240V 2A，輸出帶電阻式保險絲240V 2A. 固態繼電器（Solid State Relay，縮寫：SSR）是由半導體控制負載流經固態開關的無接點繼電器，輸入端係利用發光二極體、光電晶體、功率晶體等半導體電路所組成光耦合器，經內部控制電路觸發輸出端的矽控整流器（SCR）或雙向矽控整流器（TRIAC）進而導通負載電流，因此可以接受低壓直流或交流信號輸入之後，進而導通高壓、高功率之輸出電流，具隔離輸出入及控制高功率輸出電流之效果。
- 1、歐姆龍5V固態繼電器240V 2A，輸出帶電阻式保險絲240V 2A.
- 2、尺寸：57*55*25(長*寬*高）淨重：40g
- 3、輸入電源：5V DC (160MA)

4-channel 5v Solid State Product description
A solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals. SSRs consist of a sensor which responds to an appropriate input (control signal), a solid-state electronic switching device which switches power to the load circuitry, and a coupling mechanism to enable the control signal to activate this switch without mechanical parts. The relay may be designed to switch either AC or DC to the load. It serves the same function as an electromechanical relay, but has no moving parts.
Features:
1.Omron 5V solid state relay 240V 2A，output with resistive fuse 240V 2A
2.Size: 56.6mm*55.4mm*24.0mm
3.Weight:36.4g
4.Input power: 5V DC (≤160MA)
5.Trigger signal voltage:
Low level: 0-1.5V relay on
High level: 2.5-5V relay off
Module interface:
Input part:
DC+: connect the power supply positive (press the relay voltage power supply)
DC-: the cathode of a power supply
CH1: 1 relay module signal trigger end (low level trigger effective)
CH2: 2 relay module signal trigger end (low level trigger effective)
CH3: 3 relay module signal trigger end (low level trigger effective)
CH4: 4 relay module signal trigger end (low level trigger effective)
Note:
1.Module power supply: Power must be DC, 5V power supply
2.The control terminal voltage of the module: This module can only be used to control the AC current, can not control the DC current
Package include:
1 x 4-Channel Solid State Relay Module
