Product Description:

The CSH01.1C-ET-NNN-NNN-NNN-NN-S-NN-FW module is a controller card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It occupies the master slot in an IndraDrive automation rack and coordinates axis motion, field communication, and local I/O processing. Within an industrial cell, this card translates high-level application commands into drive-level signals, allowing analog sensing, digital states, and Ethernet networking to be combined on a single platform.

Analog circuitry begins with an input impedance of 160 kΩ, so most standard process transmitters can be connected without loading their output. The card’s analog channel can source up to 1 mA and drive a 5 kΩ load while maintaining a step size of 19.5 mV per increment, supporting basic speed or pressure references. For controls networking, the board offers Multi-Ethernet routing that automatically negotiates protocols over a 100Base-TX physical layer, allowing EtherNet/IP, EtherCAT, or PROFINET communication without hardware changes. Legacy equipment can still be integrated through the RS-232 service port, which sustains transfers up to 115 kBaud for parameter backup and service access. Digital inputs draw only 3 mA and recognize an ON state at 15 V, which helps limit sensor power demand in distributed panels.

Discrete actuation is handled by outputs that deliver 500 mA per channel and a combined 1000 mA across each group, so contactors and small solenoid valves can be driven directly. The onboard relay is rated for 1 A and switches up to 30 V DC, giving an isolated path for safety chains or fault annunciation. Network cabling stays simple because the Ethernet ports accept lines up to 100 m maximum, while the diagnostic RS-232 link is limited to a 15 m run to avoid signal loss. Final signal reconstruction at the drive uses an 8-bit converter, which suits coarse analog reference generation rather than high-resolution motion profiling.
