Product Description:

The CSH01.1C-PB-ENS-EN2-NNN-S1-S-NN-FW is a motion control card manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It slots into IndraDrive power modules and generates axis command signals, processes local I/O, and exchanges fieldbus data. In industrial automation systems such as packaging machines, pick-and-place robots, and conveyor lines, it provides real-time motion coordination between servo axes and higher-level PLCs. By integrating communication, interpolation, and diagnostics on a single board, the controller reduces cabinet space and wiring complexity.

Sensor conductors connected to the analog input stage face an input resistance of 160 kΩ, so voltage-mode transducers are not loaded by the controller. The module sources an analog command of 5 V with a maximum drive capability of 1 mA, and this low current helps protect downstream drive inputs from excessive dissipation. Discrete loads such as relays can be switched directly by the digital outputs because each channel supplies up to 500 mA. For networked operation, the board communicates over PROFIBUS-DP, and its bus transceiver supports data rates up to 12 MBaud, allowing rapid command updates and alarm reporting on busy machine networks.

The diagnostic console is accessed through an RS-232 port whose maximum throughput is 115 kBaud and remains reliable over cable runs as long as 15 m, which helps simplify cabinet layout. Integrated Safety Technology I/O accepts a nominal supply of DC 24 V and can deliver up to 1.6 A to light curtains, emergency-stop devices, and gate switches, so separate safety relays are not always necessary. Two encoder channels are present; the first supplies 12 V through a D-Sub 15 connector, while the second supports EnDat 2.1, 1 Vpp, or 5 V TTL formats for feedback flexibility in multi-servo installations.
