3.5. Connection Technique
connection technique: plug-in terminal screws
nominal cross section: 1.5 mm² (0.002 square inch)
unifilar/fine-strand (AWG 16)
length on which the wire has to be stripped : 6 mm (0.2 inch)
The wires are connected with the module by means of terminals. The terminal screws are integrated captively into the
terminal strips. All terminal strips are pluggable and can be detached from the module.
The best way to take the pluggable terminal strips off the module will be performed by assistance of a small screwdriver
placed as a lever between terminal strip and module front.
No more than 2 leads should be connected with one clamp. In this case the leads should have the same conductor
cross section.
For the binding of stranded wire we recommend the use of wire end ferrules.
Notice:
The connection of the wiring respectively the plug out and plug in of the terminal strip is only allowed in a
power off status.
Notice:
In order to prevent disturbing influences on the sensor signals and the module shielded wires have to be used
for the power supply, the bus connection and the signal lines.
3.6. Power Supply
Voltage Range
+10 ... +30 VDC
Power Input
max. 1 W
Protection
excess current (0.1A slow
. blowing fuse)
excess voltage
polarity conversion
Figure 3.2 Connection of the distribution voltage
Non-regulated DC voltage between +10 and +30 VDC is sufficient for the power supply of the
Datalogger IDL 101
. The
input is protected against excess voltage and current and against polarity conversion. The power consumption remains
approximately constant over the total voltage range, due to the integrated switching regulator.
