Product Description:

The CSH01.1C-PL-ENS-NNN-MD2-NN-S-NN-FW is a motion-control logic card in the CSH Advanced Controllers series from Bosch Rexroth Indramat. Installed in a drive rack, the card combines axis processing, encoder evaluation, and discrete I/O so that a servo system can exchange position, status, and command data with a higher-level PLC in real time. Its role in industrial automation is to coordinate motor drives, translate feedback from position transducers, and route control signals to field devices without requiring additional external interface boards. This integrated approach helps reduce extra wiring and keeps signal handling inside the control platform.

The card accepts discrete inputs at 24 V / 3 mA, allowing proximity switches and NPN/PNP sensors to be wired directly while staying within the controller's input requirements. Discrete outputs are rated at 24 V / 0.5 A, so relays and other low-power loads can be driven without an interposing amplifier. A single-ended analog channel provides a reference of 5 V / 1 mA for speed trim or torque demand. During power-up, the circuitry draws an inrush of 4 A, so cabinet protection must tolerate a short startup surge. Control data is exchanged with the drive through a Parallel Interface, which supports fast signal updates between the logic card and the connected drive.

The MD2 expansion adds 16 digital inputs together with a matching output bank, allowing grouped machine functions to be assigned in organized blocks. A separate serial maintenance port uses RS232 for local access, while the primary encoder channel follows the SSI standard for absolute position data from compatible transducers. The onboard relay can switch auxiliary loads up to DC 24 V / 1 A, providing galvanic isolation for a fault contact or brake-release circuit. Additional onboard features include a 12 V sensor supply and a D-Sub 15 female encoder connector, which support direct connection of feedback devices and peripheral signals.
