Product Description:

The CSH01.1C-PL-ENS-NNN-NNN-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat for use in the CSH Advanced Controllers series. It is installed in Rexroth drive racks to coordinate multiple servo axes, process field signals, and forward motion commands to the power stage. Within an automation cell, the unit acts as the logic and feedback hub, translating encoder data and I/O states into position-accurate drive instructions.

The controller provides a single analog output that can source up to 1 mA at a reference level of 5 V, allowing proportional speed or torque commands to external devices. Sixteen digital inputs draw only 3 mA each and accept a logic high of 24 V; this low current demand minimizes sensor loading. Corresponding digital outputs are rated for 0.5 A, so they can switch contactors or solenoid coils directly from the board. For high-speed position latching or step-direction tasks, the TTL channel can process signals up to 400 kHz, supporting applications that rely on fast edge detection. The same I/O block includes a relay contact set specified for 24 V DC at 1 A, offering an isolated path for status signaling or safety interlocking.

The encoder interface accepts incremental or serial formats with a cutoff frequency of 500 kHz; this bandwidth prevents attenuation of fine-pitch feedback at elevated motor speeds. Signal integrity is maintained by an input resistance of 120 Ohm, and the receiver expects an amplitude of 1.0 Vpp. An onboard supply furnishes the transducer with 11.6 V DC at up to 500 mA, eliminating the need for an external power rail. When the rack energizes, the module draws an inrush current of 4 A for 100 ms, after which normal consumption falls to logic-level values. These electrical limits, together with the 16-line parallel output group, set the safe loading range for cabinet wiring and drive integration.
