Elecbee 4-Channel PC817 Optocoupler Isolation Module 3.6V-30V Voltage Level Shifter Controller Driver Board for PLC Arduino and Raspberry Pi

The Elecbee 4-Channel Optoisolator Module is the essential bridge for engineers facing voltage conversion and signal isolation challenges. It effectively solves the problem of connecting low-power logic controllers like Arduino or Raspberry Pi to high-voltage industrial peripherals. By providing a physical air gap via photoelectric isolation, this 817 optocoupler board ensures that noise or electrical faults on the load side never reach your expensive processing unit.

This voltage level shifter is designed for high-reliability interface driving. Each of the four channels is completely independent, allowing for the simultaneous control of multiple voltage levels within a single system. The board supports pulse signals up to a frequency of 4KHz, making it ideal for standard switching tasks and low-frequency PWM applications.

• Input Signal Voltage: 3.6V - 24V DC
• Output Voltage Range: 3.6V - 30V DC (10mA Max)
• Isolation Chipset: 4x Independent PC817 Optocouplers
• Mounting Dimensions: 48mm x 38mm with 42mm/32mm hole spacing

Technical product information: The Elecbee driver board is engineered for precision control signal transfer. For optimal performance, ensure the output current does not exceed 10mA to maintain signal integrity. This voltage adapter is a robust development board accessory for industrial automation, allowing for the safe triggering of MOSFETs and power transistors. Its compact footprint and standardized mounting holes make it a perfect fit for DIN-rail enclosures or custom PCB stacks requiring Mil Spec-level durability and thermal stability.
