potential output capability The jumper hat provides potential output or pulldown output to suit control needs, enabling flexible switching with compatible load configurations. Independent channels Four independent channels built with 817 optocouplers allow simultaneous voltage control. Each channel operates separately, helping prevent crosstalk and enabling scalable multichannel control. Effective isolation technology Strong antiinterference capability with effective photoelectric (optical) isolation protects the control side from noise and voltages, improving reliability in mixedvoltage environments. Versatile applications Easily drive power transistors, MOS tubes, and low power 24V relays, supporting a range of switching and driving tasks in control circuits. Use scenarios 1) Microcontroller projects requiring galvanic isolation to safely drive 24V relays and switching circuits, while keeping the control logic protected. 2) Industrial automation panels that need independent, isolated channels to drive transistor or MOS gate circuits for motor or actuator control. 3) Robotics or automation systems needing parallel, lownoise switching of multiple devices with strong isolation between the control logic and power electronics.
