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

The following conductor cross-sections are permitted: – solid 0.5 … 2.5 mm2 – finely stranded, with pin cable lug, gas-tight crimped 0.5… 2.5 mm² – Finely stranded, with ferrule 0.5 … 1.5 mm2 – Finely stranded, untreated 1.0 and 1.5 mm²

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.

Extensions

Functional extension

Max. DC voltage threshold	Display threshold exceeded
Max. AC voltage threshold	Display threshold exceeded
Min. DC voltage threshold	Displayed below threshold
times event pending	Time(s) for how long a threshold must be present in order to be displayed
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

Service

The following functions can be offered as an option. These may also require WBex components

Test button	This optional button can be used to manually activate messages or applications ¹⁾
Reset measured value	Using this option, max. or min. measured value storage can be rested ¹⁾
Release contact	The release signal is required if the WB component works autonomously and should be activated or deactivated by a simple signal.
LCD display	ACTUAL value DC ACTUAL value AC Max value DC (since last reset) Max value AC (since last reset)

1)at least one channel of the digital Inputs Extension required

Optional extension

Self-test function

With this extension, the two redundant measurement inputs can check themselves and detect errors.

Input signals

The functionality of the basic components can be extended by an internal extension OR by another WB component or “WBex” extension.
