Product Description:

The CSH01.1C-PB-EN2-EN2-CCD-NN-S-NN-FW is a modular automation controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The unit serves as the central axis and I/O processor in drive systems, coordinating analog, digital, and fieldbus signals so motion commands, sensor feedback, and status data can be exchanged between higher-level PLCs and servo drives. By concentrating these channels on one pluggable card, the controller simplifies cabinet wiring and provides a consistent interface for real-time machine control tasks.

The board offers one analog input with an input impedance of 160 kΩ, limiting loading on sensitive transducers, and it digitizes that channel in steps of 1.23 mV/inc for fine process feedback. Two analog output channels drive actuators, and each step size is 19.5 mV/inc, giving predictable scaling when commanding valves or reference speeds. Closed-loop current regulation is refreshed every 125 µs, so torque or position corrections remain tightly synchronized to the drive cycle. Seven dedicated digital inputs supplement four combined digital I/O points, and each input is recognized once the signal exceeds 15 V, permitting direct connection of 24 V field switches without extra conditioning. Additional support includes two probe inputs for position capture and a 5 V supply for EN2 encoders that require an external sensor voltage.

Base consumption is 7.5 W, letting the controller share low-capacity cabinet power supplies while keeping heat generation minimal. When driving field devices, the digital outputs can source up to 500 mA, and the onboard relay contact handles currents up to 1 A for interlock circuits. A 9-pin D-Sub provides Profibus connectivity, and RS-232 diagnostics are maintained over a cable length of 15 m, allowing a laptop to remain outside the enclosure during troubleshooting. This mix of signal interfaces allows the card to accommodate incremental sensors, limit switches, and small relays without external modules.
