Product Description:

The CSH01.1C-ET-ENS-NNN-NNN-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It functions as a compact controller that merges encoder feedback, field-level signals, and safety logic for automated machinery. Multi-protocol networking, discrete I/O handling, and Safe Torque Off capability allow the unit to coordinate motion and general automation tasks from a single module. By combining these functions in one housing, the control section can reduce the need for separate interface modules in tightly packed drive cabinets.

Electrical loading is modest because the base power demand is only 7.5 W. At power-up, the module draws an inrush of 4 A, a figure used to size upstream protection. For real-time data exchange, it offers MultiEthernet, enabling connection to several Ethernet-based fieldbuses through one port. Position feedback is accepted through the multifunctional IndraDyn/Hiperface/1 Vss/TTL encoder interface, so both incremental and absolute transducers can be wired directly. Functional safety reaches SIL3 / Cat. 3 PLe, and the integrated Safe Torque Off channel removes motor power without external relays. This lets the controller manage motion-related signals and network communication without relying on a separate feedback card.

For output duties, the unit supplies up to 24 V, 0.5 A on its digital driver, which is suitable for solenoids or contactor coils. Each probe input is limited to 24 V, 3 mA and can register pulses down to 100 ms for indexing or measurement triggers. A built-in relay gives isolated signaling at 24 V DC, 1 A, and serial diagnostics are available through an RS232 interface to complement the primary Ethernet link. The housing dimensions are 49.5 mm in width, 241 mm in height, and 103 mm in depth, conserving cabinet space while maintaining adequate clearances. Its slim housing fits beside power sections where panel depth and vertical rail space are limited.
