Hardware
The Electronic Throttle Driver Module Kit provides two H-Bridge drivers and analog position
feedback in a National Instruments CompactRIO module.
Powering the Module
The Electronic Throttle Driver module requires power from two different sources.
One source is from the CompactRIO backplane male high density D-Sub 15-pin (HD15)
connector
which mates with the module’s female HD15 connector. This power source provides a
regulated 5 volts and ground to various digital logic functions within the module. The
CompactRIO 5V source is active whenever the CompactRIO or R-Series Expansion Chassis is
properly powered. The module should only be powered at the HD15 connector by plugging it into
a CompactRIO or R-
Series Expansion Chassis. The module’s HD15 connector should not be
connected to any other device.
Another required power connection is at the external screw terminal connector. The terminals are
labeled BATT (0) and GND (9). Typical power sources will be from automotive 12V or 24V
battery systems. However, the module can accept power from a range of 6V to 32V. With no
throttles connected, the module requires up to 100mA from the external supply. Driving a single
throttle under full load requires up to 60W peak and 30W continuous. Driving two throttles at full
load requires up to 120W peak and 60W continuous.
This module requires both external power and power from the CompactRIO backplane. The
module is designed in such a way that the high current path is directed through the BATT (0) and
GND (9) terminals on the front of the module and not through the HD15 backplane connector.
The module will not be recognized by software without both power supplies active.
Warning: The external battery supply input terminals are not reverse voltage polarity
protected. Connecting power to the module in reverse polarity will damage the module.
This event is not covered by the warranty. Please refer to the
DrivvenReverseBatteryNotice.pdf document (available on the website) for a recommended
solution for protecting a system from reverse battery polarity.
