The Bosch Rexroth R-IL S3 BK DI8 DO4-PAC Bus Coupler is an inline SERCOS III interface that links Rexroth Inline I/O modules to a SERCOS III network. It provides eight digital inputs (DI8) and four digital outputs (DO4) within a single coupler unit, with the -PAC designation embedded in the part code. As part of the Rexroth Inline (R-IL) family, this bus coupler enables deterministic, high-speed communication between field devices and the automation controller over SERCOS III.
