Product Description:

The CSH01.1C-SE-NNN-NNN-MEM-NN-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. As a motion and I/O controller, it coordinates analog sensing, digital signaling, and fieldbus communication between higher-level automation systems and drive modules. In automated lines, the unit interprets process variables, issues setpoints, and supervises axis behavior, forming the real-time link that synchronizes sensors, actuators, and servo drives.

The controller accepts differential analog signals within a range of ±10 V, and its input circuitry presents an impedance of 160 kΩ, minimizing loading on connected transducers. Two output channels can source up to 1 mA at a fixed reference of 5 V, allowing direct drive of potentiometric setpoints or galvanically isolated devices. During continuous operation, the electronics draw only 7.5 W of base power, so thermal dissipation inside compact cabinets remains low. A dedicated MEM plug-in draws 2 W and supports high-speed data capture at 1 MHz, while the SERCOS interface consumes an additional 2 W for deterministic fiber-optic communication. The MEM ribbon may be installed up to 40 m from the main rack without loss of timing, supporting distributed encoder or probe locations.

The discrete section provides 11 opto-isolated digital inputs for limit switches, probes, and PLC handshake signals, complemented by four sourcing outputs that can switch loads up to 0.5 A. For inductive devices such as relays or small valves, a form-C contact is also available and is rated at 1 A and 24 V DC. When the unit is energized, it momentarily draws an inrush of 4 A for a duration of 100 ms, so supply breakers must accommodate that short pulse. This channel mix lets one controller handle servo axes, hydraulic stages, and synchronized process stations within the same control platform.
