Product Description:

The CSH01.1C-S3-ENS-NNN-MD2-NN-S-NN-FW is a single-axis motion controller card from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. Installed in Rexroth drive racks, it supplies the real-time axis logic that synchronizes drives, sensors, and higher-level PLCs through the SERCOS III network. Within an automation cell, the card processes field feedback, executes position or velocity loops, and issues deterministic setpoints to the attached power stage. This allows precise machine coordination without requiring an external PC.

The analog section of the card presents an input impedance of 160 kΩ, so connected transducers place minimal load on the source signal. Each input is digitized in increments of 1.23 mV per increment, giving fine resolution for setpoint tracking. When the controller must retransmit an analog reference, it can source up to 1 mA per output channel, which is adequate for most drive or monitor interfaces. Digital outputs are rated for 0.5 A maximum, allowing them to switch relays or indicator lamps directly. During normal operation, the board itself draws only 7.5 W, so cabinet thermal load and 24 V power supply demand remain modest even in multi-axis installations.

The encoder supply rail is held at 11.6 V typical with a continuous capability of 500 mA maximum, supporting incremental, EnDat, or Hiperface sensors connected through the D-Sub 15 interface. For on-machine switching tasks, a form-C relay is provided, and its contacts are rated at 24 V DC and 1 A for brakes or interlock circuits. Remote glass-scale feedback can be linked through the SSI port, and clocked cables up to 40 m at 1000 kHz are accepted to maintain signal integrity over long gantry axes. With sixteen extension inputs and sixteen extension outputs, the card consolidates local I/O so that auxiliary sensors or valves can be wired directly to the same control node.
