Product Description:

The CSH01.1C-PL-NNN-NNN-MD1-NN-S-NN-FW is a motion-control logic module produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The unit functions as a central processing slice inside modular drive stacks, translating field-level signals into deterministic commands for servo amplifiers and feedback devices. By combining analog sensing, high-speed probing, and discrete I/O on one board, it supports coordinated axis control in packaging lines, pick-and-place robots, and material handling cells.

The controller’s analog section accepts differential inputs with an impedance of 160 kΩ, reducing loading on external transducers. Each input is digitized in steps of 1.23 mV/Inc, allowing fine-grained position or torque feedback. On the output side, the drive can source up to 5 kΩ loads while still holding a full-scale voltage of 5 V. Commands leave the converter with an effective granularity of 19.5 mV/Inc, so analog actuators receive smooth set-point changes without staircase artifacts. These attributes align the board with velocity loops that demand low noise and predictable drift characteristics.

The PL interface supplies 16 inputs and 16 outputs arranged as groups of 4 in and 4 out, while the MD1 mezzanine contributes 12 additional inputs and 8 outputs for time-critical machine functions. Each input draws 3 mA at the standardized logic potential of 24 V, and the sinking outputs can deliver up to 0.5 A to solenoids or light indicators. High-speed capture is handled by a probe circuit rated for 1 µs edge precision with a minimum pulse width of 4 µs, ensuring encoder-based registration is not lost during fast line operation. A relay channel is also present, carrying 1 A for galvanically isolated tasks such as drive-ready signaling.
