The bidirectional DIN rail receiver RCR03 4-channel is designed for controlling two tubular motors with potential-free switching. The operating modes are differentiated for applications in roller shutter control and venetian blind control. In the standard application, the runtime is 120 seconds. For runtime-dependent applications, the runtime can be adjusted, or specific positions can be set. The terrace function allows for locking the closing direction of one or more outputs, thus preventing accidental locking out. Additionally, an Easywave neo server can be integrated into the receiver to utilize the bidirectional functionalities.
