Product Description:

The CSH01.1C-CO-ENS-NNN-MD1-S1-S-NN-FW is a modular control card produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed inside Rexroth drive racks, the card establishes real-time motion and safety logic for servo axes, field devices, and sensors in automated machinery. By combining communication, encoder evaluation, and I/O expansion on one board, it functions as the command interface between higher-level PLCs and the power electronics that energize industrial actuators. It also handles the exchange of control signals and status data between the machine control layer and the connected drive hardware during operation.

An analog input resistance of 160 kΩ minimizes loading on connected sensors, letting precision transducers drive the card without extra buffering. During normal operation the board draws only 7.5 W, so cabinet heat dissipation remains low, yet on power-up it briefly accepts an inrush of 4 A for up to 100 ms until internal capacitors charge. The CANopen bus can stretch to 500 m at 125 kbit/s, permitting distributed drives to be placed across large machines. For encoder feedback the card can source 500 mA, enough for typical incremental or absolute encoders, while its TTL counting channel accepts edge rates up to 400 kHz to capture high-speed position signals without loss. These electrical characteristics support stable signal handling in systems that combine feedback devices, remote nodes, and local control functions on the same platform.

The MD1 plug-in section offers 12 × 24 V digital inputs for limit switches or proximity sensors, along with 8 × 24 V transistor outputs for contactors, pilot lights, or drive-enable lines. Communication with adjacent power modules is routed through the X60 5-Pole Spring Terminal Co connector, which simplifies wiring because no crimp tools are required. The card also carries an onboard analog output rated at 5 V / 1 mA for reference generation and provides safety I/O with 24 V logic levels at 3 mA input and 0.5 A output, allowing direct connection of emergency-stop circuits and other machine safety signals.
