Power
Battery power must be supplied to designated power-up digital inputs, since the controller's 3 to 12 Vdc
regulated power supply is not available when the controller is in lower power mode.
Module supply voltage/maximum current ratings
PLUS+1
®
modules are designed to operate with a nominal 7 to 36 Vdc power supply. The modules will
survive with full functionality if the supply voltage remains below 36 Vdc.
Specifications
Description Units Minimum Maximum Comment
Allowed voltage at pin Vdc 0 36
Allowed module current A 0 Consult module data sheets for maximum allowable
current.
SRon Minimum voltage rise rate for
power turn-on
V/ms 1 — The voltage applied to the power pins must exceed
this value to guarantee the device will power-up.
Ton Turn-on time ms — 250 From applied battery power to application software
start.
Caution
PCB damage may occur. To prevent damage to the module all module power supply + pins must be
connected to the vehicle power supply to support advertised module maximum output current capacity.
DO NOT use module power supply + pins to supply power to other modules on a machine.
Lower power mode
This feature gives OEM designers the ability to implement automotive-like features in their machine
control system design. If the lower power mode feature is not implemented, this controller has the same
operating characteristics as any other PLUS+1
®
controller.
When used as a lower power mode controller, supply power to the module is connected directly to the
battery. Lower power mode initiation is defined by the controller's application software: PLUS+1
®
GUIDE
programmers define the conditions under which the controller is to put into lower power mode. When in
lower power mode, controller outputs are set to zero, sensor power supply is off and the controller
consumes a small amount of current.
Controller lower power mode current consumption
Supply voltage Lower power mode current consumption
12 Vdc 20 mA
24 Vdc 20 mA
Either of two conditions will wake up the controller:
•
The power supplies can be re-energized by cycling battery power.
•
Generating a positive/rising edge on one of several inputs:
