9.5. Extension box input/output interface
The extension box input/output interface option (code 984405500) makes it possible to:

Convert an alternating voltage (example 230V 50Hz) into a logic signal 1

Easy connection of the inputs of the 16 logic channels

Insulation of the 16 logic inputs (250V=~ between channels, 250V=~ between channels and
ground)

Easy connection of the alarm outputs by a screw terminal

Power supply of an external accessory with 3.3V, 5V or 12V by a screw terminal.
Connection of the logic channels according to the signal voltage:

0 to 250V =~
connection 0 - 250V=~ logic channel
red
black
by insulated pin plug between red and black terminals
max. usable voltage: 250V continuous or alternating
typical trip threshold (AC or DC): 48V
frequency: 45 to 440Hz
undetected low threshold (AC or DC): 0 to 10V
detected high threshold (AC or DC): 60V to 250V
insulation: 250V=~ between channel and ground

0 to 48V=~
by a screw terminal between the points 1 and 3 of the screw terminal box
max. usable voltage: 48V (AC or DC)
frequency: 45 to 440Hz
typical trip threshold (AC or DC): 9V
undetected low threshold (AC or DC): 0 to 2V
detected high threshold (AC or DC): 10V to 48V
insulation: 50V=~ between channel and ground
connection 0 - 48V logic channel
