The power supply may disappear in case of overload (> 0.2A). In this case, you must turn off the device a few
minutes before turning it on again.
14.5 External voltage box input/output interface
The external voltage 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 =~ red
connection 0 - 250V=~ logic channel
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

connection 0 - 48V logic channel
1
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 0 to 10V=~

2
connection 0 - 10V logic channel 1
by a screw terminal between the points 1 and 2 of the screw terminal box max. usable voltage: 10V continu ou alternatif
frequency: 45 à 440Hz typical trip threshold (AC or DC): 2.2V undetected low threshold (AC or DC): 0 to 1V detected
high threshold (AC or DC): 3V to 10V insulation: 50V=~ between channel and ground
Response time:
To detect the alternating current, the signal of the logic channels is rectified and filtered.
Typical delay for a rising signal: 10ms
Typical delay for a falling signal: 50ms
Use:
Link the box to the input/output connector of the device with the 25-pin connector provided as an option.
Connect the logic channels to record with respect of the maximum acceptable voltages.
Power supply / Alarms:
max current 3.3V: 200mA max current 5V: 200mA max current 12V: 200mA
Alarm A contact 1 & 2: open contact in case of alarm, insulation 50V
