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 using full H-bridge or independent half-bridge configurations.

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, half bridge and full-bridge switching, all configurable per channel.

Built-in current measurement, over current, reverse polarity, thermal protection, and load dump compliance ensure reliable operation under demanding conditions.

Applications

  • Bi directional control of inductive and resistive actuators

  • High side or low side actuator control as switch (on-off)

  • High side or low side actuator control with duty cycle (0-100%)

  • Half bridge actuator control

  • Full bridge actuator control

  • Current controlled actuators

Features

  • Continuous current up to 10 A

  • Can be used as full bridge, 2x half bridge, high and/or low side switch (on-off and duty cycle controlled)

  • Current of each channel can be read out (only for high side configuration)

  • 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 6 to 24 Volt

Technical specifications

The technical specifications are listed in the table below.

Min Nom Max Unit
Supply rail voltage (normal operation) 6 24 Volt
Nominal load current individual channels 10 A
Peak load current individual channels 14 A
Nominal load current H-bridge configuration 10 A
Peak load current H-bridge configuration 14 A
Switching frequency (duty cycle selected) 1 10 kHz
Duty cycle resolution 1 %

* The maximum total module current consumption may not exceed 15A.

CAUTION! Be aware to connect all the supply pins and all ground pins before controlling any actuator. By connecting only one or two pins, the processor board and module are not able to distribute the amount of current that is required. When a safety relay is used, only cut the module supply, not the module ground! Lastly, but no less important, connectors may never be hot plugged, remove supply before removing or installing connectors! The processor board and module can be permanently damaged!

Pinout Moduline II, III & IV

The eight module expansion slots are directed to four connectors in front of the controller. Connector A,B,D and E. If a module is plugged into a specific expansion slot, one half of the corresponding connector is used to interface this module. The picture below gives an overview of the connectors with their related module expansion slots.

Connector C ( in the middle) is used for controller supply and some optional CAN bus connections.

The four module expansion slots are directed to the two main connectors of the controller. Connector A and B. If a module is plugged into a specific expansion slot, one half of the corresponding connector is used to interface this module. The picture below gives an overview of the connectors with their related module expansion slots.

Connector B ( on the left in this view) is also used for controller supply, a controller enable- and reset-input and a CAN bus interface. Connector A also offers a CAN bus interface and on top of that two controller enable inputs.
