Product Description:

The CSH01.1C-S3-NNN-NNN-MD1-NN-S-NN-FW is a compact control section from Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Installed in IndraDrive systems, it executes motion commands, PLC logic, and field communication for servo axes and auxiliary equipment. By combining drive control with programmable I/O handling, the unit streamlines cabinet layouts while providing deterministic command processing for industrial automation lines, packaging cells, and material-handling stations.

Its analog input channel accepts a ±10 V reference signal for speed or torque loops. The corresponding analog output can drive monitoring equipment with up to 5 kΩ of load at a nominal 5 V level, enabling closed-loop feedback to legacy devices. Field communication is handled through SERCOS III, so deterministic data telegrams synchronize the unit with drives and remote I/O. On the MD1 plug-in, the controller supplies 12 digital inputs and eight digital outputs; the inputs are sensed at 24 V / 3 mA, while the output channels are intended for field actuators. The standard operator panel provides menu navigation and status indication without connecting an external PC.

All switching outputs, both on the MD1 module and on the motherboard, share a capacity of 24 V / 0.5 A, allowing direct drive of contactors or solenoids. Two galvanically isolated relay contacts are rated at 24 VDC / 1 A for interposing control circuits that exceed the transistor limits. Network wiring is terminated on a pair of RJ45, 8-pin sockets that form the SERCOS ring, and their signaling adheres to IEEE 802.3, allowing standard Cat-5e cabling without proprietary pinouts. Because the controller includes no safety logic, external safety relays must supervise the emergency-stop chain. When the Digital I/O Extension option is installed in slot 3, additional points can be mapped through the controller, and the single onboard digital input follows the same threshold as the MD1 channels.
