PC817 Optocoupler Isolation Module 1-Channel

The 1-Channel Optocoupler Isolation Module provides reliable galvanic isolation and voltage-level conversion for digital control signals. Each channel uses an optocoupler input and a driven output stage, with selectable input ranges to accept common control voltages and screw-terminal wiring for secure connections. LEDs indicate input activity per channel, and the outputs can be configured to drive either high-or low-trigger loads. The module is compact and panel-mountable or DIN-rail mountable (with optional carrier/bracket), making it suitable for automation, industrial control, and DIY projects that require robust isolation between control electronics and field devices.

Features

• Two selectable Input control signal ranges (3-12V and 9-24V).
• Output signal range: 3-24V.
• LED indicator for each input.
• Dedicated 2-pin screw clamp terminal for each input and output.
• Output can drive high or low-triggered load.
• Four (Ø 3.5mm) mounting holes for easy installation.
• Dimensions: 50 X 23 X 17mm.
