Power supply
The unit
must be connected to a +12 to +48 V battery voltage through a 1 amp. fuse. The
use of a fused supply wire is important for not damaging the wires related to the unit in
case of a short circuit etc.
case of a short circuit etc.
Digital inputs
The voltage required for activating of a digital input is dependent on the configuration of
the input ports.
the input ports.
Digital output
The digital output has the type indication ”LO-side switch”, that connects the output to 0V
“ground”, when the output is active. This output can be used to control a relay powered
from an external DC supply voltage. The maximum current drawn from the output is
200mA and the voltage from the external supply voltage must not exceed 60 V DC.
The output is protected against short circuits, overload and is also protected against over
voltage. For further information about connection possibilities of the digital output, see
chapters about installation later in this manual.

Motion/acceleration sensor
The unit has a built-in 3 axis acceleration sensor that is able to activate the unit if it, as a
consequence of disconnected supply voltage, is in stand-by mode. When motion is
detected it will also cause activity on ‘Input 7’ on the ME401-9 microcontroller portal.

1-Wire input
• The 1-wire input can be used to read Dallas iButton for access control. The 1-wire
input is only operational when supply voltage (12 to 48 V) is present. It cannot
operate on internal battery alone.
