Product Description:

The CSH01.1C-NN-ENS-EN1-MD1-S1-S-NN-FW controller section is manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. In automated machinery, it acts as the local control core that conditions sensor signals, drives field outputs, and passes data through its RS-232 serial interface to supervisory equipment. Separate supply rails for encoders and resolvers allow the board to energize feedback devices, while dedicated safety contacts let the drive system fulfill machine-level stop functions without extra hardware.

Power is introduced through a DC 24 V control input, and the card draws a base load of 7.5 W during normal operation. At startup, the circuitry accepts a surge of 4 A for a maximum window of 100 ms, which should be considered when sizing cabinet fuses and power supplies. Analog motion commands leave the board through an 8-bit voltage output channel, and the associated current is limited to 1 mA to protect downstream devices. A separate digital I/O expansion bus uses only 1 W, so additional terminals add minimal thermal load. These electrical loads should be considered when sizing the control power supply and cabinet airflow.

The motion interface produces signals with a precision of 19.5 mV/Inc, while the auxiliary bus can source up to 1.1 A to external sensors and actuators. Field wiring terminates on twelve digital inputs and a separate block of 12 extension inputs, while eight extension outputs provide command signals to contactors or indicator lamps. For functional safety, output switching is restricted to 0.5 A per channel, and a safety relay in series can carry 1 A for hard-wired interlocks. Feedback devices may be powered from the 12 V standard encoder rail or the 8 V resolver HSF supply, ensuring compatibility with both incremental encoders and resolver transducers without external regulators.
