Product Description:

The CSH01.1C-PL-EN2-NNN-MD1-NN-S-NN-FW is a motion and logic controller module developed by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It mounts in Rexroth drive racks and coordinates servo axes, digital I/O, and field devices in automated machinery. By combining high-speed parallel signaling with serial diagnostics, the module acts as the central command layer that schedules motion profiles, supervises safety chains, and exchanges status data with a plant-level PLC.

Its front edge provides two analog input channels that accept signals up to ±10 V; a 160 kΩ input resistance protects upstream transducers from loading effects while allowing precise differential measurements. A separate analog output can source 5 V reference levels to external amplifiers or sensors. The controller logic and I/O are powered from a dedicated DC 24 V supply, and a startup inrush of 4 A should be considered when selecting the cabinet fuse. Position feedback from rotary or linear encoders is processed through the multi-protocol EnDat 2.1 / 1 Vpp / 5 V TTL interface, enabling interpolation and electronic commutation without additional converter boards.

Discrete control paths include 16 parallel inputs, 16 parallel outputs, 12 MD1-rated inputs, and 8 MD1-rated outputs. Cyclic data exchange with host PCs is available through the RS232 port at up to 115 kBaud. The board's internal logic, gate drivers, and communication layers draw only 15.5 W, minimizing panel heat. For actuator signaling, the integrated relay can switch DC 24 V / 1 A loads, and time-critical strobes are supported with a maximum pulse width of 100 ms. These resources let the controller manage sensor sampling, status flags, and interlocks in assembly cells and packaging lines without requiring separate I/O expanders.
