Product Description:

The CSH01.1C-SE-ENS-NNN-MEM-L1-NN-FW control section is produced by Bosch Rexroth Indramat for its CSH Advanced Controllers series. As a motion-logic processor that snaps into IndraDrive power sections, it coordinates servo drives, feedback devices, and machine safety states in automated cells. The unit interprets analog sensor data, handles high-speed digital events, and forwards deterministic telegrams over a SERCOS optical ring, thereby acting as the central command element within a distributed industrial automation architecture.

Its signal conditioning starts with an A/D converter resolution of 12 bit, allowing moderately fine scaling of process voltages. The two differential analog inputs accept ranges of ±10 V, so common field transmitters can be connected without additional scaling. For actuator feedback it provides a regulated analog output level of 5 V referenced to logic ground. Discrete devices are driven through digital outputs rated at 24 V / 0.5 A, enough to energize contactors or optical couplers directly. The integrated encoder connector supplies 500 mA of sensor current, letting it power incremental or multiturn encoders without external power rails. Depth is 103 mm, height is 241 mm, and width is 49.5 mm, so the module fits alongside other IndraDrive sections on a standard DIN rail.

High-speed edge detection is supported by a limit counter frequency of 500 kHz, while separate TTL inputs capture pulse trains up to 400 kHz for registration tasks. During installation the SERCOS fiber plug is secured with a coupling torque of 0.6 Nm, preventing signal loss in vibration zones. Functional safety is addressed through an integrated start-lockout that conforms to Stop Category 0; its monitoring contact switches DC 24 V at 1 A and the supervision circuit observes a 24 V, 3 mA signal. The master interface operates exclusively as SERCOS, enabling deterministic cycle times without additional fieldbus cards.
