PWM Signal Generator Module Adjustable Pulse Frequency Duty Cycle Square Wave GL

Powered by FrooitionvlidscromPWM Signal Generator Module Adjustable Pulse Frequency Duty Cycle Square Wave Description⚙️ Digital PWM & Pulse Signal Generator — 3.3–30 V, 1 Hz–150 kHz, Start/Stop, Countable Pulses

Programmable square/rectangular wave source for drivers and logic inputs: DC/BLDC/stepper motor drivers, servo control inputs, LED dimmers, solenoid drivers, PLC inputs, robot actuators, and more.

Heads-up: This module outputs a logic signal (≤ 30 mA) whose amplitude equals the supply voltage. It does not directly power loads (lamps, motors, solenoids) — use it to control a driver.

🌟 Highlights

• 🧭 Two Modes

  • PWM (continuous): Set frequency + duty (0–100%), runs continuously.

  • PULSE (counted): Set high time, low time, start delay, and pulse count (1–9999 or ∞).

• ▶️ Start/Stop Control — On-board button and external switch input

• 🔌 Wide Supply: 3.3–30 V DC with reverse polarity protection

• 🧰 Easy Wiring: 5.08 mm screw terminals; compact enclosure

📐 Specifications

• Supply Voltage: 3.3–30 V DC (reverse-protected)

• Frequency Range: 1 Hz – 150 kHz (≈ ±1.5%)

• Duty Cycle: 0–100% (1% steps)

• Pulse Count (PULSE mode): 1–9999 or ∞ (display “----”)

• Start Delay: 0.000–9999 s (min step 1 ms)

• High/Low Pulse Widths: 0.000–9999 s (min step 1 ms)

• Output Drive: ≤ 30 mA (signal only)

• Output Amplitude: Equal to supply voltage (Vin)

• Size: 79 × 43 × 30 mm

🔌 Connections (typical)

• V+ / V−: Module power (3.3–30 V DC)

• OUT / GND: Logic output to your driver/PLC input (share ground)

• EXT SW: External toggle for Start/Stop (if header present)

Examples

• Stepper/DC driver: OUT → PUL/CLK (or PWM), GND → GND

• LED driver with PWM dimming: OUT → DIM/PWM, common GND

• Solenoid/Motor via MOSFET/SSR: OUT → gate/control, driver handles load power

🧭 Quick Operation

PWM Mode (continuous output)

1. Select PWM

2. Set frequency (e.g., 1 kHz)

3. Set duty (e.g., 35%)

4. Start to run; Stop to pause

PULSE Mode (timed pulses)

1. Select PULSE

2. Set Start Delay (optional)

3. Set High Time & Low Time (e.g., 50 ms / 150 ms)

4. Set Count = 1–9999 or ∞

5. Start to execute; Stop to pause/hold

🧠 Tips & Notes

• For hobby servo-style signals (≈50 Hz, 1–2 ms), use PULSE mode with precise widths.

• Keep leads short at high frequencies; ensure a solid ground to minimize noise.

• If your target expects 5 V logic and you power the module at 12–24 V, use a level shifter/optocoupler.

• Do not exceed 30 mA from the output pin.
