Product Description:
Bosch Rexroth Indramat created the CSH01.1C-PL-EN1-EN2-MD2-NN-S-NN-FW for use in modular servo-drive racks within the CSH Advanced Controllers series. The board operates as the processor and signal interface for one axis group, linking upstream PLCs to the power section of each drive. By combining encoder feedback, discrete I/O, and analog references, it supports closed-loop positioning and the interlocks required in material-handling, packaging, and assembly lines. This arrangement lets motion commands and feedback signals pass through a single control stage rather than separate interface modules.
The analog stage accepts command voltages across an input span of ±10 V and is buffered by a typical impedance of 160 kΩ, allowing remote signal sources to drive the port without loading errors. Two single-ended outputs can retransmit reference data, and each channel is factory limited to 5 V, 1 mA so downstream electronics are protected from overcurrent. Basic logic tasks are supported by sixteen 24 V inputs routed through on-board optocouplers, and each point draws only 3 mA at the rated threshold. High-speed host coordination is handled through a Parallel Interface that transfers status words and setpoints simultaneously rather than serially. The same header maps sixteen discrete inputs and sixteen outputs directly to the drive backplane for deterministic latching during machine operation.
An expansion plug-in raises capacity to 16 inputs and 16 outputs and introduces a digital SSI channel for Absolute Position Detection. These terminals can switch actuators at up to 24 V, 0.5 A, which allows light-duty loads to be connected without separate relays. All expansion and base lines converge on a shielded 37-pin D-Sub connector that carries data, ground, and enable lines to the cabinet backplane. For precision feedback, the card accepts a primary HSF or RSF interface and a secondary port designated as EnDat 2.1 / 1 Vpp / TTL, while supplying the transducer with an unregulated 5 V feed. A dry ready relay rated 1 A at 24 V DC provides a system interlock.
