Product Description:

The CSH01.1C-ET-EN2-NNN-MD1-L2-S-NN-FW industrial control card is produced by Bosch Rexroth Indramat as a component of the CSH Advanced Controllers series. Mounted in drive racks, the card provides axis control, I/O processing, and network connectivity for servo systems in automated cells and machine tools. It acts as the local intelligence layer inside IndraDrive power sections, translating fieldbus commands into motion sequences and processing feedback to maintain precise torque or position loops. This arrangement lets one control platform coordinate motion tasks and peripheral signals without requiring a separate standalone controller for each axis.

Its analog front end offers an input impedance of 160 kΩ, reducing sensor loading and helping low-level reference signals remain stable. The two analog outputs can source up to 5 V, 1 mA for reference generation toward external actuators or interface circuits. Eleven on-board digital inputs accept a logic level of 24 V, 3 mA, and four digital outputs deliver switching signals rated at 24 V, 0.5 A for contactors, indicator lamps, or interposing relays. Motion data and diagnostics are exchanged through an Ethernet port that conforms to the 100Base-TX standard, enabling deterministic communication in real-time automation networks, while additional RS232 connectivity supports local setup and service access.

The card’s Multi-Ethernet backplane accepts Profinet, EtherNet/IP, and Sercos III frames, which gives the control platform flexibility when it is connected to different plant networks. This protocol range works with the serial port’s maximum cable length of 15 m for nearby operator or service panels. Axis feedback is processed through the EnDat 2.1 interface, which also supports 1 Vpp and 5 V TTL encoders so the controller can receive high-resolution position data for dynamic interpolation and stable closed-loop response. For machine safety circuits, the integrated Safe Torque Off function removes drive energy without interrupting the fieldbus link, and relay contacts rated at DC 24 V / 1 A can forward STO status to external interlocks. Twelve MD1 digital inputs and eight MD1 digital outputs expand the available I/O when the application needs additional field-level signal handling.
