The CPC12 bus controllers are connected with the EM12-T supply module. This enables an independent supply of the circuit protectors and also of the ControlPlex® controllers. The bus controllers record all status information and measuring values of the REX12D and REX22D BASE +COM circuit protectors and enable their control and parametrisation. With the CPC12 ControlPlex® controllers it is also possible to visualise data via the web server and Web Server use it as maintenance interface. A high transparency, clear troubleshooting and remote access increase machine uptime significantly. The CPC12...
