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.
Schematical Representation.
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

Pinout controller connector.
The module supply and output ports are directed from the module to the controller connectors. Each connector interfaces 2 modules. Only the half of the pins of one connector are dedicated to one module. Refer to the document ‘Processor board guidelines’ for more specific information about module location and connector selection. Be aware of the location of the installed module before wiring the connector.

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.
