Description
The functional module “WB-ADC” is used wherever electrical flows are measured and their currents are monitored. In addition, based on the collected data, the control decisions can be passed on to third-party systems.
Determines direct currents and their flow directions.
The functional module “WB-ADC” is used wherever electrical flows are measured and their currents are monitored. In addition, based on the collected data, the control decisions can be passed on to third-party systems.
The following measuring functions can be carried out, evaluated and displayed via digital outputs or (if available) transmitted via a protocol:
Depending on the expected current strength, the currents can be determined in different ways:
1.) Directly on the device
DC currents up to 20 A can be determined by connecting directly to the system
2.) Shunt resistance
3.) Hall sensor measurement

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, maximum or minimum measurement values can be saved |
Release contact |
The release signal is required if the WB component works autonomously and is to be activated or deactivated by a simple signal |
LCD display |
Current current flow |
For security reasons and by popular demand, an on-site configuration option was omitted.
The threshold values can be set at the factory.
If you need several different threshold values in your systems, you can do this using one of our service cases Perform CM1010 / VLD1010. 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 connected to a WB-MC or WB-HS.
The functionality of the base components can be extended by an internal extension OR by another WB component or WBex extension.
