Siemens 6ES7148-4CA00-0AA0 SIMATIC ET 200pro PM-E 24V DC 10A Remote I/O Accessory

The Siemens 6ES7148-4CA00-0AA0 is a 24 V DC power module for the SIMATIC ET 200pro distributed I/O system, feeding load voltage to the electronic modules mounted on the same backplane segment. It carries up to 10 A on the internal busbars at ambient temperatures up to 55 degrees C and protects the circuit with an exchangeable fuse plus reverse-polarity protection against destruction.

Technical Specifications

Selection Notes

With a 10 A busbar rating up to 55 degrees C, this module covers the higher-current end of ET 200pro I/O groups on a single power segment; specify it where several electronic modules share one PM-E feed rather than splitting the station into extra potential groups. The exchangeable fuse means a short circuit on the load side is cleared without replacing the whole power module. It mounts to the ET 200pro backplane through a connection module that is ordered separately.

Applications

ET 200pro is a modular, machine-mounted distributed I/O system, so this power module typically sits mid-station wherever a new load-voltage group starts on the backplane. The group error LED and missing-load-voltage diagnosis are reported back to the controller with the rest of the station's diagnostics, so a blown fuse or disconnected supply on this segment shows up without a separate wiring check.
