8 Channel PC817 Optocoupler Isolation Board 3.6-30V Driver ALAMSCN

Description

Product Overview

The 2‑piece 8‑channel PC817 optocoupler isolation board from ALAMSCN is engineered for high‑reliability photoelectric isolation in demanding industrial environments. Each channel accepts a driving signal voltage between 3.3 V and 24 V while delivering an isolated output voltage ranging from 3.3 V to 30 V, with a maximum output current of 10 mA per channel. The board measures 4.13 × 2.87 × 0.55 inches and weighs only 2.05 oz, making it easy to integrate into compact control panels. Its design incorporates robust PCB layout techniques, shielding, and a low‑capacitance PC817 optocoupler that minimizes cross‑talk and ensures strong anti‑interference performance even in noisy power‑line conditions.

Usage

This isolation board is ideal for applications that require safe voltage conversion and signal isolation, such as driving high‑power triodes, MOS tubes, and 24 V relays. It is frequently used in automation systems, robotics controllers, instrumentation equipment, and renewable‑energy inverters where precise timing and reliable isolation are critical. The board can also be employed in laboratory test rigs for signal conditioning, providing a clean, isolated interface between low‑level control circuitry and high‑voltage power stages. Its 8‑channel configuration allows a single board to replace multiple discrete optocouplers, simplifying wiring and reducing overall system footprint.

FAQ

What is the maximum pulse frequency the board can handle?

The PC817 optocoupler on this board is rated for pulse signals up to 4 kHz. For applications requiring higher frequencies, consider using a faster optocoupler model.

Can this board drive a 24 V relay directly?

Yes. Each channel can source up to 10 mA, which is sufficient to activate most low‑power 24 V relays without additional driver circuitry.

Is the board suitable for use with high‑current power triodes?

The board is designed to provide isolation and control signals for power triodes, but the actual current handling of the triode must be managed by an external driver stage. The board’s output voltage range (up to 30 V) is compatible with many triode gate requirements.

What warranty and support are offered?

ALAMSCN provides a one‑year limited warranty covering manufacturing defects, along with email and phone technical support to assist with integration, troubleshooting, and documentation.

How do I mount the board in my enclosure?

The board’s dimensions (4.13 × 2.87 × 0.55 in) and standard 0.1 in pitch pin layout make it easy to secure on a DIN rail or within a custom panel using standard mounting holes or adhesive pads. The silk‑screen labels help identify each channel during installation.
