Description
1.8V/3.3V/5V/12V/24V High Low Level Trigger Relay Opto-Isolator Relay 1/2/4 CH 30A Diy Relay Module with Optocoupler
Product Description
series relay module, the input adopts the way of photoelectric isolation to amplify the input signal, which effectively solves the problem of the controller controlling the relay output in the case of insufficient driving capacity. This product is widely used in: SCM GPI0 pin, I/0 board, Raspberry Pi, PLC
Features
1.The 832A-1C-F-C relay is used, and the contact current is up to 30A. The input adopts the optocoupler isolation mode, and the signal circuit and the power supply circuit are completely isolated. Each channel has an LED indicator for displaying the status of the current channel. The module base adopts 35mm standard "DIN" rail installation. No base is fixed with screws. 2.Trigger signal positive control, negative control compatible design. 3.The input trigger signal current is 5mA, which is suitable for signal amplification of single-chip GPI0 pin, l/0 board Raspberry Pi, PLC and other controllers.
