High power module connections

The High power module is a digital output module and can be used to drive high powered electrical loads such as pumps, fans, heaters, refrigerators and Hi-Fi equipment etc.

Channel capabilities:

  • Up to 20A draw per channel

  • Load current measurement

  • Over current protection

  • Under current detection

  • Soft fuse

  • Voltage detection

  • Voltage protection up to 32 V dc

Output options:

  • Resistive load

  • Inductive load (external fly-back diode required)

  • Incandescent lamp driver

  • PWM mode

  • Low load detection

Note

The High power module requires a minimum current draw of 50mA, If your desired application requires loads of 200mA or less, consider using the Input/Output on a Remote module or the Signal module, as they have been designed for this purpose.

Important

  • The negative power cable (0 V return) of the system must be connected to the same battery negative as all input and output devices that are being controlled or monitored by that system.

  • Each load must have both a supply and return connection to the module.
