3pcs 4-Channel PLC Amplifier Circuit Board MOS FET PWM 3-20V to 3.7-27VDC 10A Driver Module

Description

Product Overview

The Coliao 4 Channel PLC Amplifier is engineered to provide precise and reliable pulse‑width modulation (PWM) control across a broad voltage range. Designed with a compact footprint of 5 × 3.23 × 1.14 inches and weighing only 2.4 ounces, the module integrates a high‑quality ultra‑small optocoupler that delivers strong anti‑interference capability and complete electrical isolation between input and output signals. Input voltage accepts a flexible 3 V to 20 V PWM signal, while the output stage can generate a stable DC voltage from 3.7 V up to 27 V, supporting continuous currents up to 10 A and a total power handling of 400 W. This combination of features makes the board suitable for demanding industrial applications where both precision and durability are essential.

Key technical specifications include a PWM frequency range of 0 Hz to 1 kHz, a digital high‑low trigger source (DC 3 V – 20 V), and four independent channels each equipped with indicator LEDs for real‑time status monitoring. The module’s robust construction utilizes high‑temperature resistant components, ensuring long‑term reliability even under continuous heavy loads. The board’s layout follows industry‑standard safety guidelines, providing a secure platform for integrating with motor drivers, LED drivers, solenoid valves, and other high‑power equipment.

Usage

In industrial automation, the 4‑channel PLC Amplifier serves as a versatile interface between programmable logic controllers (PLCs) and a variety of actuators. For example, it can regulate the speed of DC motors in conveyor systems, adjust the brightness of high‑power LED lighting arrays, and control the flow of solenoid‑operated valves in fluid handling equipment. Its wide input voltage tolerance allows seamless integration with existing control panels that operate on 5 V or 12 V logic levels, while the high output voltage capability enables direct driving of devices that require up to 27 V.

Beyond factory floors, the module is equally effective in hobbyist and prototyping environments. Makers can employ the board to create custom lighting rigs, power‑efficient water pumps for small aquaponics setups, or variable‑speed drives for robotics projects. The four independent channels provide the flexibility to manage multiple loads simultaneously, reducing the need for additional driver boards and simplifying wiring layouts. Its compact size also makes it ideal for mounting inside enclosures where space is at a premium.

FAQ

What type of PWM signal does the module accept?

The amplifier accepts a standard PWM signal ranging from 0 Hz to 1 kHz with a voltage level of 3 V to 20 V. This makes it compatible with most PLCs, microcontrollers, and Arduino‑type boards.

Can the module drive multiple motors simultaneously?

Yes, the board provides four separate channels, each capable of delivering up to 10 A. You can connect up to four motors or other loads at the same time, provided the total power does not exceed the 400 W rating.

Is the output voltage adjustable?

The output voltage is set by the input PWM duty cycle. By varying the duty cycle, you can smoothly adjust the output from the minimum of 3.7 V up to the maximum of 27 V, giving precise control over speed or brightness.

How does the optocoupler improve performance?

The built‑in optocoupler provides complete electrical isolation between the control side and the power side. This isolation prevents high‑voltage transients from reaching the control circuitry and reduces electromagnetic interference, resulting in more stable and reliable operation.

What safety certifications does the product have?

Coliao’s PLC Amplifier complies with RoHS and CE standards, ensuring it meets European safety, health, and environmental protection requirements. The unit has also passed internal thermal and overload testing to guarantee safe operation under load.
