The requirements of machine and plant construction regarding machine uptime and a consistently high production quality are increasing. Stable processes are based on a reliable and transparent DC24V protection and power distribution system.
E-T-A’s CPC12 bus controller has a separate DC24V power supply and allows independent supply of the circuit protectors. It records all status information and measuring values. These data are visualised with the internal web server. Via the field bus interface, the data are also made available to the superordinate control systems.
E-T-A’s REX12D system in combination with the CPC12 bus controller was designed specifically for the requirements of the machine construction and process control industry. The REX12D modular power distribution system combined with the CPC12 bus controller meets all requirements.
- Maximises plant and machine uptime through clear failure detection, high transparency and remote diagnosis
- Saves space through a slim design of the circuit protectors and the potential modules
- Increases flexibility of system planning through many different modules meeting the demands of DC24V power distribution
- EM12-T supply module
Up to 40 A can be fed into the supply module. Power is further distributed without further accessories via the REX connection technology with connector arm to the connected circuit protectors.
This innovative technology reduces wiring time and eliminates time-consuming disassembly of busbars in the event of replacement or system extension.
- CPC12 bus controller
The CPC12 bus controller collects status information as well as measuring values of the connected circuit protectors. These data are transmitted to the superordinate control systems via the field bus interfaces for PROFINET (CPC12PN), EtherNet/IP (CPC12EN), Modbus TCP (CPC12MB) and EtherCAT (CPC12EC). Thus, the CPC12 creates transparency and remote access to all essential information and functions of the DC24V power distribution.
General station descriptions
- REX12D circuit protectors
The double channel REX12D electronic circuit protector protects the system in the event of overcurrent and short circuit. It reliably disconnects the faulty circuit and prevents voltage dips in the DC24V power distribution.
It allows protection of loads with a standard-compliant cable protection to EN60204-1 as well as the use of an adjustable protector version with current ratings from 1 - 10 A.
