2 Channel Power Bridge Module
The 2 Channel Power Bridge Module is a GOcontroll Moduline compatible expansion card designed for high-power actuation. It adds a robust, dual-channel output stage capable of driving inductive or resistive loads as two independent half bridges, or as a single full H-bridge by combining both channels.
Each output channel supports continuous currents up to 10 A and peak currents up to 14 A, making it ideal for controlling motors, solenoids, or other heavy-duty actuators. The module allows for high-side, low-side and half-bridge switching, configurable per channel.
Built-in current measurement, over current, reverse polarity, thermal protection, and load dump compliance ensure reliable operation under demanding conditions.
Applications
- Bidirectional DC motor control (forward and reverse via full H-bridge)
- Linear actuator extension and retraction
- Hydraulic and proportional valve actuation
- Pump and fan speed control
- Solenoid, relay and contactor switching
- Heating element and resistive load control
- Current-controlled actuators
Features
- Two independent power output channels
- Usable as two independent half bridges, high-side / low-side switches, or as a full H-bridge by combining both channels — on/off or duty-cycle (PWM) controlled
- Configurable PWM switching frequency up to 10 kHz
- Continuous current up to 10 A
- Per-channel current read-out
- Each output is short circuit and over temperature protected
- Module supply is reverse polarity protected
- Module power supply is load dump protected (ISO 7637)
- Bad ground connection detection (earth loop protection)
- External supply voltage range from 8 to 32 Volt

* The maximum total module current may not exceed 15 A
Connectors may never be hot-plugged. Remove power before removing or installing connectors.
Connect all supply and ground pins before driving an actuator; otherwise the processor board and module can be permanently damaged.
If a safety relay removes the module power, only interrupt the positive supply (+) — never the ground.
The total module current consumption may not exceed 15 A.
