Descripción
Three-way 220V optocoupler isolation module, which has greatly improved the driving ability compared with the previous generation module. It adopts NPN transistor output. The saturated conduction current can reach 100-300MA. It can be connected to any single-chip microcomputer or PLC.The module can be used to detect the presence of 220V AC, and 220V photocoupler is turned on and outputs low level. No 220V non-conduction output high output is stable high and low level. It can be directly connected to the IO port of the single-chip microcomputer for detection, or it can be connected to the PLC to be compatible with all PLC inputs.The output power supply can be DC: 3V~24VInstructions for use:1. The common neutral wire of the high voltage input terminal can monitor whether the 3 live wires are energized2. NPN output, when 220V has power, the module is turned on and outputs low level, when 2020V is out of power, the module is blocked and pulled high by the resistance3. The power supply voltage at the output must be a DC voltageVoltage range: DC3V-24VCan be connected to single-chip microcomputer or PLC or other weak current monitoring modulesNote:In practical use, after the module is powered on, do not touch any components in the white wire frame on the board, because it is high voltage, pay attention to the safety of electricity!
