Siemens 6ES7193-6BP20-0DA0 ET 200SP Base Unit

Siemens 6ES7193-6BP20-0DA0 is the SIMATIC ET 200SP BaseUnit BU15-P16+A10+2D (BU type A0) designed as the single-slot backbone for a decentralized I/O assembly, with a compact 15 mm width, 141 mm height and 35 mm depth. It uses push-in terminals and supports conductor cross-sections from 0.14 to 2.5 mm², powered by a 24 V DC supply with external protection via a 10 A miniature circuit breaker (type B or C). The base unit provides backplane connectivity for ET 200SP modules, offering a P1/P2 bus current up to 10 A, an AUX bus up to 10 A, and process-terminal current up to 2 A, with isolation tested up to 707 V DC; operating temperature ranges from -30 to +60 °C and installation altitude up to 5,000 m. This BU is commonly used to organize and distribute I/O for sensors, actuators, and discrete control applications within SIMATIC ET 200SP automation panels.
