2 Channel Power Bridge Module

General

The 2 channel power bridge module is a GOcontroll Moduline IV compatible expansion card to add a high power H-bridge to your modular controller. Instead of single bridge configuration, the module can also be used as 2 high power half bridges.

Local control an monitoring of output

Communication with processor board

Module rail supply

Output channel 1

Output channel 2

Module ground

Software configurable interface circuit

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

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.

For example let’s assume an Bridge Module is plugged into expansion slot 5:

  • The corresponding connector is D
  • The module supply pins are: 5-7
  • The module ground pins are: 24-26
  • The signal output pins are: 11-13, 17-19

Pinout Moduline Mini I.

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.

For example let’s assume an Intput Module is plugged into expansion slot 4:

  • The corresponding connector is B
  • The module supply pins are: 1-3
  • The module ground pins are: 26-28
  • The output signal pins are: 10-12, 18-20

Be aware to connect all the supply pins and 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. The processor board and module can be permanently damaged.
