Siemens 6ES7193-6BP20-0DC0 SIMATIC ET 200SP BaseUnit Type C0 BU20-P6+A2+4D Remote I/O Accessory

The Siemens 6ES7193-6BP20-0DC0 is a SIMATIC ET 200SP BaseUnit type C0 (BU20-P6+A2+4D) that provides push-in terminal connections for I/O modules on the ET 200SP backplane, rated 24 V DC or 230 V AC and 10 A current carrying capacity. It includes 2 AUX terminals in a new load group and measures 20 x 117 mm (W x H), starting a new potential group for load segmentation.

Technical Specifications

Selection Notes

BU20-P6+A2+4D (type C0) starts a new load group and adds 2 AUX terminals, so this slot's process supply can be isolated from the BaseUnits upstream of it. Pick it over a bridged BaseUnit when a downstream module needs a separate voltage or potential domain, such as isolating a noisy actuator circuit or stepping from a 24 V DC zone to a 230 V AC zone. Since the slot itself supports both DC and AC rated values, confirm the connected I/O module's own voltage class before wiring 230 V.

Applications

Potential-group segmentation within an ET 200SP station, a mounting slot for analog or digital I/O modules that need an isolated process supply, and mixed-voltage-zone distributed I/O stations.
