High Density Power Distribution Module (HDPDM)

Features

The High Density PDM is a Class 1 ES-Key module with 20 high current positive outputs, 1 low current ground output, and 10 selectable polarity inputs designed for use within an ES-Key electrical system network. Starting with hardware revision B the 10 Inputs have “MFI” (Multi-Function Input) capability. This allows the inputs to be polarity selectable inputs or have analog capability (0-5volt, 0-30volt, 4-20mA, Thermistor, and Frequency). The ground polarity output also has the ability to be reconfigured to a voltage reference output that is selectable between 5 volt and 9 volt.
