E-T-A introduces a low-cost CAN-bus controlled
decentralised electrical power distribution system
E-T-A Circuit Breakers, quality designer and manufacturer of a broad range of electromechanical and electronic products for circuit protection, has introduced a new, simplified,
low-cost, decentralised electrical power distribution system, each module offering up to 10
outputs rated up to 8A/10A per channel. E-T-A PowerPlex Compact provides localised
monitoring, control and reliable protection of safety-critical electrical circuits, at the same
time offering reduced cabling costs and build time. Communication with the PowerPlex
modules is via CAN-bus using SAE J1939 based protocols. Each localised module will
handle up to 60A, providing programmable control based on up to 12 digital and 3
analogue inputs as well as programmable overload protection.
Currently available as a 12V DC version, E-T-A PowerPlex Compact is straightforward to
install and can be used for applications such as battery monitoring of split charging
circuits, undervoltage monitoring and control, remote operations based on level and flow
sensors, responding to limit switches in tail lifts, dimming of lights and for timed controls.
It will switch loads and protect them and the electrical harness against overcurrent and
short circuits. Featuring high-end power semiconductors with integral protective elements
for switching and protection, there are no mechanical components such as relays which
may be subject to wear, vibration and shock.
One or more PowerPlex modules are positioned as required around a vehicle to facilitate
the local connection of loads, switches and sensors. Each module can collect sensor data
from level and temperature sensors, for example. E-T-A PowerPlex is an open system
featuring two CAN-bus communication channels which enable control via an E-T-A touch
panel or keypad(s), if required, to enable load switching, and monitoring and display of
data from analogue and digital sensors.
The initial programming of each module via a cable linked PC is straightforward, using
configuration software supplied with the product. It enables, for example, the linking of
inputs and outputs, programming of timer functions and activation of dimmers. The

current ratings for overcurrent protection of the load circuits and time characteristics can
also be programmed.
