Product Description:

The CSH01.3C-PL-EN2-EN2-CCD-NN-S-NN-FW control section is manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed for installation inside drive cabinets, it serves as a compact automation node that delivers analog setpoints, digital switching, and multiple data links to coordinate machine functions on the factory floor. Its architecture focuses on precise signal timing and integrated communications so that servo axes, sensors, and plant supervisory systems can exchange information without external adapters. By concentrating these interfaces on one module, wiring is reduced and diagnostic access is simplified.

Five analog output channels share a conversion time of 10 µs, allowing near-real-time voltage updates. Each channel supplies up to 1 mA and changes in steps of 19.5 mV per increment. This 256-level resolution is expressed through an 8-bit data width. For discrete control, the board provides 16 parallel digital outputs that can be grouped to deliver a combined current of 1000 mA, while 16 matching digital inputs accept standard 24 V field signals. A dedicated EN2 encoder port is powered from a 5.0 V rail and can source 350 mA, which supports external feedback hardware.

The module’s communication layer is organized around a parallel interface that exchanges control words with the power section, while cross-communication to neighboring drives runs at 100Base-TX Ethernet speed through an 8-pin RJ-45 jack that follows the IEEE 802.3 protocol. An integrated RS-232 service port reaches a maximum throughput of 115 kBaud over cable runs up to 15 m, supporting parameter backup and service access. Individual digital outputs are protected to 500 mA, which helps keep short-circuit energy within safe limits during actuator faults. This arrangement helps prevent an unplanned shutdown of the entire output group when a single output channel is overloaded.
