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.
WB-ADC
Determines direct currents and their flow directions.

Function
The following measuring functions can be carried out, evaluated and displayed via digital outputs or (if available) transmitted via a protocol:
- Detects overcurrents and undercurrents
- Determines flow directions
- Energy measurement
- Storage of the maximum current value that the system has measured since the last reset or start-up
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
- Integration of a shunt resistor that is connected in series in the circuit
- By external sensors up to 6kA
- Calibration sensor measurement unit
- plus auxiliary voltage +-15V/6W and a 4-20mA input
3.) Hall sensor measurement
- Integration of a Hall sensor measurement through which include the live wire.
- This eliminates the intervention in the infrastructure
- By external sensors up to 6kA
- Calibration sensor measurement unit
- plus auxiliary voltage +-15V/6W and a 4-20mA input

Extensions
Functional extension
| Max. current threshold | Display threshold exceeded |
| Min. current threshold | Displayed below threshold |
| times event pending | Time(s) for how long a threshold must be present in order to be displayed |
Operation
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 |
| 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 |
Parameterization
For security reasons and by popular demand, an on-site configuration option was omitted.
The threshold values
If you need several different threshold values
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.
Input Signals
The functionality of the base components can be extended by an internal extension OR by another WB component or WBex extension.
