Function and Equipment

The control system offers extensive functions that can be configured quickly and easily. The available signal relays can be assigned a range of fixed functions, such as simple traffic light control or position reporting.

The optionally available add-on board with four additional output relays can be used to expand the WST-18 to include additional special functions such as a traffic light control system that regulates the right of way.
