Product Description:
The CSH01.1C-PL-ENS-MEM-MA1-L2-S-NN-FW controller is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It serves as the logic and safety interface between Indramat drive inverters and field devices inside an automated station, executing axis commands while supervising the Safe Torque Off circuit to remove drive power when required. The module’s function set combines analog motion commands, encoder evaluation, and digital relay handling, making it the core coordination layer in industrial automation cells that require synchronized motion and immediate shutdown capability.
The base analog output provides up to 5 V at 1 mA, allowing the controller to send low-power reference signals directly to positioners or monitoring equipment. Internal power draw is limited to 7.5 W, so thermal load inside the cabinet remains modest. For drive emulation tasks, the pulse generator can switch at 1 MHz, supplying high-resolution step trains to external counters or frequency converters. Incoming differential encoder lines have an input resistance of 120 Ω, a value chosen to match standard line-driver impedances and minimize signal reflections. When powering encoders, the board supplies 11.6 V DC, covering typical 5 V to 12 V sensor requirements without an external supply.
Incremental TTL feedback can be sampled at up to 400 kHz, maintaining accurate velocity calculation even on high-speed axes. Two extension inputs and two extension outputs share an identical range of ±10 V, and their conversion accuracy is fixed at 12 bits, giving 4096 discrete steps for process values. Sixteen parallel digital inputs and sixteen parallel digital outputs handle standard 24 V signaling for interlocks and status lamps, while the relay channel is rated to switch 24 V at 1 A DC loads such as contactors. A female 9-pin D-Sub houses the safety connector, carrying the wiring for the Safe Torque Off path so the controller can conclusively remove energy to the drive when a protective circuit is opened.
