B&R’s FORMULA X system, described as a decentralized backplane, manages analog and digital I/O signals locally or remotely and interfaces with Multimach and HDM valve islands. Available modules, in 8-, 16- or 24-signal versions, can be configured as Input, Output or mixed I/O. Each module features four connections: signal input, signal output, 24 VDC power input and power output for subsequent modules.
