Product Description:

The CSH02.1B-CC-EC-NN-SB-NN-NN-FW is a modular motion and logic controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Within an automation cell, it coordinates axis drives, field devices, and safety modules through deterministic network protocols so multiple machine sections can operate in sync. By combining command processing, feedback acquisition, and machine-level communication, the unit provides centralized sequence control for packaging, printing, and general material-handling equipment that require repeatable sub-millisecond response times.

For process interfacing, the controller offers 3 differential analog inputs, 2 analog voltage outputs, 11 digital inputs, 5 configurable I/Os, and a relay rated at 1000 mA. Output rails deliver up to 500 mA per digital channel. Each analog output steps in increments of 24 mV per increment, while current feedback channels sample at 11-bit resolution with an input resistance of 300 Ω. The platform communicates with drives as a SERCOS III master, supporting real-time position updates over fiber or copper rings. Internal circuitry dissipates only 17 W, so cabinet heat load remains low without external signal conditioners.

Motion capture uses the multi-encoder interface to register incremental, absolute, and SSI feedback sources without additional cards. The integrated Safe Motion Bus relays emergency-stop and speed-related safety commands between the controller and drive. Voltage sensing channels resolve signals at 13-bit resolution and are buffered by an input impedance of 300 kΩ to minimize circuit loading. A dedicated probe input with a pulse width tolerance of 4 µs time-stamps external trigger events for synchronous positioning. This arrangement supports high-speed axis coordination while reducing external wiring between feedback and safety circuits.
