Rexroth B-Design fieldbus components include support for Sercos III and Ethernet/IP for valve manifold systems Series HF03-LG, HF04, and CD01/02-PI. The valves include body sizes with 10, 15, 18 and 26mm widths. All electric, pneumatic, supply and exhaust connections are on one plane, enabling clean installation. Discrete output modules control up to 2 amps current draw per point, and modular expansion of discrete and solenoid outputs is possible.

The SERCOS III version follows the same standard platform as other Rexroth Bus Direct Control (BDC) protocols. Sercos III features up to 32 outputs per valve manifold and up to four valve manifolds can be controlled from one bus module. 

The EtherNet/IP version follows the same standard platform as other Rexroth bus Central Mount System (CMS) protocols. EtherNet/IP features up to 48 inputs per valve manifold in addition to solenoid and discrete outputs, and up to four valve manifolds can be controlled by one bus module. The standard module works with EtherNet/IP, Modbus TCP and TCP/IP protocols.
