6pcs 1 Channel PC817 Optocoupler Isolation Module 24V Signal Isolation Board Optoelectronic Isolator Anti-Interference Converter
6pcs 1 Channel PC817 Optocoupler Isolation Module 24V Signal Isolation Board Optoelectronic Isolator Anti-Interference Converter
Key features
- Circuit Isolation Function: This 1-channel PC817 Optocoupler Isolation Module provides electrical Signal Isolation between microcontrollers and inductive loads to prevent circuit interference during operation
- Low Voltage Input Range: The board supports input voltages of 24V, and outputs DC 1.8V to 24V, allowing it to interface with sensors and devices operating at different voltage levels
- Electrical Specifications: The module features an isolation voltage greater than 3000V, a maximum input current of 50mA, and a working temperature range of -55 to 110 degrees Celsius
- Signal Transmission Parameters: Designed for current amplification with a maximum application signal frequency of 5KHz and an operating current greater than 1mA for electronic signal conversion
- Physical Connection Interface: The unit includes 5.0 pitch screw terminals for wire connections and a card rail bracket for physical mounting on equipment rails
Product OverviewThe 1-channel optocoupler isolation module uses 5.0mm pitch screw terminals for convenient wiring and features a card rail bracket for easy installation. It provides isolation and anti-interference protection for microcontroller circuits when driving inductive devices like motors. It matches low MCU output levels with high driven module voltages (e.g., converting to 24V for PLC inputs). It also functions as an inverter, a high-voltage isolated detector (e.g., 12V sensor to 5V MCU), and a current amplifier for weak MCU outputs. The module uses optocoupler isolation for stable, reliable performance and long service life.SpecificationsInput Signal Voltage: DC 3V~5V / 12V / 24V (Optional)Output Signal Voltage: Wide voltage suitable for DC 1.8V-24VEL817 Characteristics:Isolation voltage: > 3000VMaximum input current: 50mAOperating current: > 1mAMaximum output current: 50mA (Requires input current of 15-20mA)Operating temperature: -55~110°CMaximum application signal frequency: 5KHz
Free shipping included. 30-day hassle-free returns.
