7. Electrical Connection
7.1 Connecting Cable
Proper shielded instrument cable is highly recommended. Low capacitance
twisted pair 7 x 0.3 mm (0.5 mm²) for use with the DON and any remote receiving
instrumentation. Typical cable would be Belden® 9363 or similar. Connect the
cable shield to DC common or designated grounding terminal at the receiving
instrument. Remember to only connect the end of the cable shielding at the
receiving instrument (not the DON) to ensure proper interference protection.
Please be sure not to run the connecting cable within a common conduit or in
close proximity to conduit with high inductive loads or power sources. This could
result in noise or inducted errors to the output signal or result in damage to the
electronic components. Always run the instrument cables in a separate conduit or
within a common conduit with other low power cables. Max cable length should
be limited to 3280 ft (1000 m).
7.2 Electrical connection for integrated electronics options
The electrical connection of the integrated electronics options always requires the
electronics cover to be dismantled. High pressure models incorporate the cable
inlet into the electronics cover.
The connecting cable must be routed through the cable duct and connected in
accordance with 7.3.1 to 7.3.4. The connecting terminals are of the plug-in type,
and can be taken out of the terminal compartment to facilitate connection.
7.2.1 Hall-effect sensor with active pulse output (H0 option)
The H0 electronic option combines a hall-effect sensor with an active push-pull
output stage. A three-phase electrical connection is used. The output is actively
switched, either to the input terminal vVs or to GND. The external input
terminal voltage is 8 to 30 V
DC
. No additional external wiring is required (e.g. pull-
up resistor). The high signal corresponds approximately to the +Vs input terminal
voltage and the low signal approximately to 0 V.
The electrical load can be connected to either the input terminal voltage or GND
Max. output current (power source or sink): 100 mA (short-circuit protected).
