Compatible with any Rexroth scalable PLC/PAC, Inline I/O Modules include SSI and INC IN, which bring encoder feedback capabilities. All 3 modules help wiring and hardware costs. Model SSI includes 4 inputs and position detection, which can identify motor position during rotation. Direction can be indicated with INC encoder quadrature signal, allowing machine builders to incrementally fine tune motor to specific degrees. Providing PWM and step and direction control, Model PWM/2  enables machine builders to alter width of pulse, and reduce the temperature of the drive and the amount of energy consumed.
