Product Description:
The CSH02.1B-CC-EC-CN-NN-NN-NN-FW is a modular control unit produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Intended for multi-axis servo systems, the module coordinates drive functions, collects machine feedback, and issues deterministic command sequences to actuators on automated production lines. By combining motion supervision, communication routing, and low-level I/O processing in a single rack-mount format, the controller simplifies cabinet wiring and provides the deterministic backbone required for packaging, printing, and general assembly installations.
The controller’s discrete interface is sized for mid-range machines. It provides 16 digital inputs that accept 24 V signals from limit switches or proximity sensors, and 5 digital outputs capable of sourcing up to 500 mA each for contactors or indicator lamps. Two analog outputs share a conversion granularity of 24 mV/incr, allowing proportional valve or speed reference generation, while three analog inputs capture process values from load cells or potentiometers. All circuitry is powered from a 24 V DC logic supply, and inrush is limited to less than 5 A with a 1 ms pulse so auxiliary supplies are not overstressed. The integrated relay contacts can switch loads up to 30 V, eliminating the need for external interposing relays in low-power circuits.
For real-time networking, the unit operates as a SERCOS III master, exchanging cyclic setpoints and feedback with compatible drives. A built-in CANopen port acts as an I/O expansion bus; it can address 127 CANopen nodes and is factory-terminated with a 124 Ω resistor to preserve signal integrity at the end of the segment. The multi-encoder interface accepts incremental, EnDat, or SSI feedback, so axis position can be verified directly at the controller. Total energy draw does not exceed 17 W, which permits passive convection cooling inside densely populated panels while keeping thermal load low.
