Bosch Rexroth Corp.: Inline I/O modules

Bosch Rexroth’s three new inline I/O modules for encoder feedback, step and direction control, and pulse width modulation are compatible with any Rexroth scalable PLC / PAC.

Designed for motion-based machine builders and industrial OEMs, the new modules can be used with any controller from the Rexroth line. The new I/O modules include the SSI and INC IN modules, which provide powerful encoder feedback capabilities for even the smaller, less expensive PLCs, such as Rexroth’s L10. The SSI and INC can handle a large number of axes and can dictate position and speed. The SSI features four inputs and position detection which can identify the motor position during its rotation. The INC encoder pulses quickly as the axis rotates. Based on a combination of signals that comes from the drives, the encoder module can identify the position of the motor in its rotation. The PWM/2 module provides pulse width modulation and step and direction control, giving machine builders more flexibility to alter the width of the pulse. This can be used to reduce the temperature of the drive and the amount of energy consumed. The step and direction aspect also allows the module to be used with stepper drives and motors.
