Product introduction:The 1-channel optocoupler isolation module adopts 5.0 pitch screw terminals for convenient wiring. The module is suitable for isolation when the output level of the single-chip microcomputer is used to drive inductive components such as motors, and anti-interference protects some circuits of the single-chip microcomputer. The output level of the single-chip microcomputer is low, and the driving voltage of the driven module is high for level matching. For example, some PLC inputs require 24V voltage, which can be converted by this module. Used for inverter, can invert the input signal and output. Used for high voltage detection, for example, the output signal level of a certain sensor is 12V, and the voltage of single-chip microcomputer is 5V. This module can be used to isolate and detect. Current amplification For example, when the output current of the MCU is too small to drive certain circuits, this module can be used for amplification. The module adopts optocoupler isolation, which is stable and reliable and has a long service life.Product parameters:Input signal voltage: DC 3V-5V/12V/24V(optional)Output signal voltage: wide voltage suitable for DC1.8V-24VEL817 features:Isolation voltage is greater than 3000VInput current max 50MAWorking current>1MAMaximum output current 50MA (input current must be 15-20MA)Working temperature -55~110 degrees.Maximum application signal frequency: 5KHz
