WB-VDC

Measures DC voltages and AC components
Voltage withstand capacity up to 6000 VDC/10 ms

Description

The ‘WB-VDC’ functional module is used wherever power voltages of 200 VDC or higher need to be measured and monitored. Furthermore, the data collected can be used to make control decisions that are then relayed to third-party systems.

Examples of applications include:

  • Feed-in points at substations for railway infrastructure

  • Return conductor points at substations in railway infrastructure

  • in the generation and storage of energy

  • Truck charging stations

  • Boat charging station

  • Train charging stations

  • Service battery in a BOAT

Mounting on a 35 mm DIN rail in accordance with EN 60715

Mains connection and inputs and outputs:

– Screw terminals,
– Stripping length 9–10 mm
Note: To connect potential-free contacts to
the actuator inputs, use cables with twisted-pair
conductors.
The following conductor cross-sections are permitted:
– Solid core 0.5–2.5 mm²
– stranded, with pin-type cable lug, gas-tight crimped 0.5–2.5 mm²
– stranded, with ferrule 0.5–1.5 mm²
– stranded, untreated 1.0 and 1.5 mm²

Weight

ca. 250g

parameterisation

For safety reasons and in response to numerous requests, the option to configure the device on site has been omitted.

The thresholds can be set at the factory.

If you require several different threshold values in your systems, you can achieve this using the CM1010 / VLD1010 service kit. Different parameter sets and software updates can be stored on the service kit and loaded via an adapter.

It is also possible to transmit the parameters via a SCADA system (for this, the system must be connected via a WB-MC or WB-HS).

Functional description

The following description covers the basic functions of the device. These can also vary considerably due to extensions or customer functions.

Extensions

Functional enhancement

Threshold value for maximum DC voltage

Display: Threshold exceeded

Maximum AC voltage threshold

Anzeigen Schwellwert überschritten

Minimum DC voltage threshold

Value below the displayed threshold

Times
Upcoming event

The time(s) for which a threshold value must remain active before it is displayed

Monitored auxiliary voltage for external sensors

The sensors are connected to the device and powered by it. The current consumption is monitored, and conclusions are drawn regarding the sensor’s functionality.

Number and duration of overvoltage and undervoltage events

Example: Only when a pulse of> 0.2 ms has occurred more than three times is it counted, and a signal is sent after the fourth occurrence

Any signal delay

superordinate systems should only trigger an alarm when an actual value falls below or exceeds a threshold

Arbitrary signal pause / minimum signal length

Ensuring data transfer to third-party systems

Operation

The following functions may be offered as optional extras. These may also require WBex components
