Description
The functional module “WB-VDC” is used wherever power voltages from 200VDC are measured and monitored. In addition, based on the data collected, control decisions can be passed on to third-party systems.
Application examples include:
- Feed-in points of substations in railway infrastructure
- Return conductor points from substations in railway infrastructure
- in the generation of energy and its storage
- truck charging stations
- BOAT charging station
- train charging stations
- power battery in a BOAT

Parameterization
For security reasons and by popular request, there was no on-site configuration option.
The threshold values can be set at the factory.
If you need several different threshold values in your systems, you can do this using the CM1010 / VLD1010 service case. Different parameter sets and software updates can be stored on the service case and imported using an adapter.
It is also possible to transfer the parameters via a SCADA system (the system must be configured using a WB-MC or WB-HS must be connected).

Function
The following measurement functions can be carried out, evaluated and displayed using the digital outputs or, if available, transmitted via a protocol
-
Detects high and low voltage
-
DC voltage measurement
-
AC voltage measurement
-
Measurement of mixed voltage
-
Storage of maximum DC voltage value (since last reset)
-
Save max voltage value AC (since last reset)
Voltage up to +/- 3000 V can be reached through a direct connection to the system can be determined directly on the device.

|
Monitored auxiliary voltage for external sensors
|
The sensors are connected to the device and supplied via it. The power consumption is monitored and conclusions are drawn about the functionality of the sensor.
|
|
Number and time of voltage overshoot and undershoot
|
Example Only if an impulse of > 0.2 ms has occurred, this is counted and after 4 times a signal is sent
|
|
Any signal delay
|
higher-level systems only signal messages when an ACTUAL value is below or exceeded
|
|
Any signal pause / min. signal length
|
Ensuring transmission to third-party systems
|

|
|
Release contact
|
The release signal is required if the WB component works autonomously and should be activated or deactivated by a simple signal.
