PC817 Optocoupler Isolation Module 8-Channel

Description

PC817 Optocoupler Isolation Module 8-Channel The 8-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. DIN Rail mounting using PCB carrier or PCB bracket ( Optional ). Dimensions: 129 X 50 X 17mm. Specifications Parameter Value Channel Count 8 channels Input Control Ranges 3–12V or 9–24V (selectable) Output Signal Range 3–24V Indicators 1× LED per input channel Input Connector 2-pin screw clamp terminal (per channel) Output Connector 2-pin screw clamp terminal (per channel) Trigger Modes High-trigger or low-trigger selectable output Mounting Holes 4 × Ø3.5mm Mounting Options Mounting holes, PCB carrier, PCB bracket (DIN-rail) Dimensions 129mm x 50mm x 17mm Applications Isolation and level shifting between microcontroller I/Os and industrial controllers or relays. Protecting low-voltage control electronics from noisy field circuits and ground loops. Signal interfacing for PLC inputs/outputs, motor controllers, alarm systems and sensor networks. DIY automation, test rigs, and retrofit control panels requiring safe separation of domains. Multi-channel opto isolation in robotics, lighting control, and remote I/O expansions.
