6 Channel Output Module.

The 6 channel Output Module is a GOcontroll Moduline compatible expansion card to add 6 general purpose output ports to your modular controller. The outputs are protected and configurable individually for a wide range of applications. The configuration can easily be set by the user in Node-RED.

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 (this configuration requires 2 output ports)

  • Current controlled actuators

Features

  • Each output is independent configurable

  • High side, low side, half bridge, full bridge and 3 phase control can be selected

  • 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
Maximum current for each channel* 5 A
Switching frequency (duty cycle selected) 1 17 kHz
Duty cycle resolution 0,1 %

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

Pinout Controller Connector

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.

Module 3 & 4

Connector D

The picture below shows the connector pinning from the Output module. Be aware of the different pinouts when the module is plugged into even or odd module slots.

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

  • The corresponding connector is D
  • The supply pins are: 5-6-7
  • The ground pins are: 24-25-26
  • The output channel pins are: 13-19-12-18-11-17

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.
