Shop Optocoupler & Isolation Modules by Type

Our optocoupler and isolation module range may include products such as:

PC817 Optocoupler Modules: Common isolation modules used for input and output isolation in microcontroller and control projects.
Multi-Channel Optocoupler Modules: 1 channel, 2 channel, 4 channel and 8 channel optocoupler boards used to isolate multiple control signals.
AC Input Isolation Modules: Modules used to detect suitable AC input signals while providing electrical isolation to the low-voltage control side.
Input Isolation Boards: Interface modules used to protect microcontroller, PLC-style or control inputs from another circuit.
Output Isolation Boards: Modules used to isolate control outputs before driving external circuits or devices.
Relay-Style Isolation Modules: Optocoupler interface boards used in switching, control and relay-style isolation applications.

Isolation Modules for Arduino, ESP32 & Control Projects

Optocoupler modules are commonly used with Arduino compatible boards, ESP32, ESP8266, Raspberry Pi compatible boards, STM32 boards, sensors, relay circuits, motor control circuits, automation projects and low-voltage control interfaces. They are useful when a signal needs to pass between two circuits but direct electrical connection is not desirable.

Always check the input voltage, output voltage, signal type, channel count, isolation rating, supply requirements, wiring method, output type, current rating and whether the module suits your circuit before ordering.

PC817 Modules, Input Isolation & Relay-Style Interface Boards

PC817-style optocoupler modules are widely used for simple signal isolation between control circuits. Multi-channel versions are useful when several signals need to be isolated on one board. AC input isolation modules can be useful where a low-voltage controller needs to detect the presence of an AC signal through an isolated interface.

Frequently Asked Questions

What is an optocoupler module used for?
An optocoupler module is used to pass a signal between two circuits while keeping them electrically isolated. This can help protect a microcontroller or control circuit from another circuit.

Are PC817 modules the same as relay modules?
No. A relay module uses a relay to switch a load. A PC817 optocoupler module provides signal isolation and is often used as an interface or isolation device, but it does not switch loads in the same way as a relay contact.

Where should bare PC817 chips go?
Bare PC817 ICs and other raw optocoupler components should go under Electronic Components > Optocouplers & Isolators. Optocoupler boards and isolation modules should go here.

Can optocoupler modules be used with Arduino and ESP32?
Yes. Optocoupler modules are commonly used with Arduino, ESP32 and other microcontrollers for isolated inputs, signal interfaces and control circuits.

Can you help me choose the right optocoupler module?
Yes. If you are unsure which module suits your project, contact AuscomTech with your input voltage, output circuit, signal type, channel count, isolation needs and wiring details.
