CURRENT PROTECTION
DIAMONDBACK Series
Similarly to the traditional electromechanical circuit breakers, the DIAMONDBACK protects electrical circuits
by closely controlling the I²t factor.
CHANNEL PARALLELING
Multiple individual channels can be paralleled in order handle large current loads. The new current rating is
calculated as the sum of the individual channel ratings. To use channels in parallel, simply tie the channels’
load pins together, put the board in maintenance mode, and program the required parallel combination.
HEALTH MONITORING
DIAMONDBACK Solid State Power Controller provides current, voltage and temperature measurements.
This information can be used to monitor electrical loads and perform tasks such as diagnostics, prognostics
and condition-based maintenance.
BLOCK DIAGRAM
DIAMONDBACK’s architecture is comprised of high side switches controlled by a central microprocessor.
The switching blocks are responsible for the control of individual channels. The processor performs all
necessary measurements, data processing, and communicates to the user’s application through a CAN
communications interface.

CAN COMMUNICATIONS
All communications between the Diamondback and the controller is conducted via a J1939 compliant CAN
communications interface. Diamondback only responds to the user’s commands, however, user’s software
is not required to operate the Diamondback Series products. Communications interface commands are
defined by Sensitron’s Interface Communications Document (ICD). Please contact us for a copy of this
