AC 220V Motor Forward & Reverse Control Board with Limit Interface – SCR Drive Module
Take precise command of your bidirectional motor applications with the TKS-M2A Motor Controller Board. Engineered for AC 220V systems, this compact SCR (thyristor) drive module delivers reliable forward and reverse motor control with built-in limit interface support — ideal for lifting motors, automated gate drives, linear actuators, and other two-way motor setups.
Key Specifications
- Model: TKS-M2A
- Input Voltage: AC 220V / 50Hz (compatible range: 180–250V)
- Compatible Motors: Bidirectional motors (3-wire or 4-wire) — see wiring diagram
- Output Power: 300W rated (max current up to 16A; a heat sink is recommended for loads above 300W to keep thyristor temperature below 105°C)
- Output Mode: Bidirectional thyristor (SCR)
- Control Mode: Switch signal trigger (non-isolated circuit — signal part included; handle with care)
- Protection Circuit: Varistor for surge protection; X2 safety capacitors on input and output to suppress spark and grid interference
- Dimensions: 90 × 50 × 28 mm
P0 Standard Edition – Operating Logic
- Self-Locking: A single trigger signal is enough — the module latches and continues running without a sustained input.
- Direction Change: When a reverse signal is received during forward rotation, the motor stops immediately and enters reverse after a 0.3-second delay.
- Limit Signal Priority: The limit input takes precedence — a forward-limit signal halts the motor instantly and prevents restart in that direction until the limit is cleared. The same logic applies to reverse limiting.
- Signal Level: Forward and reverse control signals are active-low (triggered by a brief 0V / ground-level pulse).
- Limit Input Type: Normally open (closing SW1 or connecting to ground disables forward rotation).
Why Choose This Controller?

Important Notes
- This module operates on a non-isolated circuit — including the signal lines. Proper precautions and adequate insulation are essential during installation and use.
- For loads exceeding 300W, attach an appropriate heat sink to keep the thyristor operating temperature below 105°C.
- Colors in product images may vary slightly due to display settings. Allow ±1–3 cm tolerance due to manual measurement.
- Made in Mainland China.

Frequently Asked Questions
Q: What types of motors are compatible with this AC 220V motor controller board?
A: The TKS-M2A is designed for bidirectional (two-way) motors with either 3-wire or 4-wire configurations. It is commonly used with lifting motors, linear actuators, automated shutters, and similar reversible AC motor applications. Always refer to the included wiring diagram to confirm compatibility before installation.
Q: Does this motor forward reverse control board require a continuous trigger signal to keep the motor running?
A: No. The P0 Standard Edition features self-locking logic — a single momentary low-level (0V ground) pulse on the forward or reverse input is sufficient to start and maintain motor operation. The module latches the state internally, so no sustained signal is needed.
Q: When should I add a heat sink to this SCR motor drive module?
A: A heat sink is recommended whenever the connected motor load exceeds 300W. The thyristor must be kept below 105°C for safe, reliable operation. Mounting an appropriately rated heat sink to the board's thyristor package will help dissipate heat effectively under heavier loads.
Q: Is the circuit on this motor controller board electrically isolated?
A: No — the TKS-M2A operates on a non-isolated design, which means the signal lines share a common reference with the AC power circuit. Users must exercise caution, use appropriate insulation, and follow standard electrical safety practices during installation and wiring to avoid hazards.
