The bidirectional DIN rail receiver RCR03 4-channel is designed for potential-controlled operation of two tubular motors. The operating modes differ in applications for roller shutter control and blind control. In the standard application, the runtime is 120 seconds. For runtime-dependent applications, the runtime can be adjusted or target positions can be set. The terrace function allows for the locking of 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.
