Siemens AG 6ES7 120-0BH01-0AA0 Terminal Block

Siemens 6ES7 120-0BH01-0AA0 Terminal Block is a TB16SC field-termination block designed for use with SIMATIC automation systems in the S7-1200 family. The block provides 16 termination points in a compact housing to securely terminate and route field-wiring from sensors, actuators, and I/O modules to a PLC or SC module, supporting neat, organized control-panel wiring. The TB16SC family offers flexible termination options, including screw-type and spring-loaded terminals, and this particular part number places the device within that versatile family for Siemens' modular automation ecosystems. In typical applications, technicians install this terminal block to expand the wiring capacity of a Siemens controller in compact automation projects, enabling direct, reliable connections in space-constrained panels. The official designation 6ES7 120-0BH01-0AA0 ensures compatibility with other Siemens SIMATIC components that use the TB16SC interface, making it a suitable choice when upgrading or expanding established S7-1200 or SIMATIC SC installations.
