PC817 Optocoupler Isolation Module 4-Channel

PC817 Optocoupler Isolation Module 4-Channel

The 4-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

• Four optically isolated channels for safe galvanic separation.
• Selectable input control ranges: 3–12V or 9–24V.
• Output signal range: 3–24V (suitable for driving typical logic and relay circuits).
• LED indicator for each input channel to show activity.
• Dedicated 2-pin screw-clamp terminals for each channel’s input and output for secure wiring.
• Outputs configurable to drive either high-triggered or low-triggered loads.
• Four Ø3.5 mm mounting holes for easy installation.
• Optional DIN-rail mounting using a PCB carrier or bracket.
• Compact footprint and low profile for space-constrained panels.
