Product Description:

The CSH01.1C-SE-EN2-NNN-MA1-S1-S-NN-FW controller belongs to the CSH Advanced Controllers series and is manufactured by Bosch Rexroth Indramat. It functions as a compact control section that combines analog I/O, digital safety circuitry, and high-speed fieldbus communication for coordinating motion axes in automated machinery. Within an automation cabinet, the module converts sensor signals, issues setpoint commands, and exchanges deterministic data with drives and PLCs. Its compact format suits cabinet installations where control, feedback, and safety functions must be grouped in one section.

Two differential analog input channels accept ±10 V signals and are digitized with 12-bit resolution, allowing the controller to monitor process variables with fine granularity. Correspondingly, two analog outputs source up to 10 mA across the same ±10 V span, so the module can transmit derived setpoints to external actuators; the output resolution matches the input resolution. Command exchange with drives occurs on the SERCOS network, while position feedback is routed through the multifunction EnDat 2.1 / 1 Vpp / 5 V TTL encoder port for compatibility with several feedback signal types. During power-up, the electronics draw a 4 A inrush current, and each enable pulse can extend to a maximum of 100 ms, preventing unintended latching when safety doors cycle.

Power consumption is limited to 18.5 W, permitting dense rack installation without exceeding typical cabinet cooling capacity. Functional safety wiring terminates on a D-Sub 9 connector; the logic inputs are rated at 24 V / 3 mA, and the dedicated solid-state outputs can switch 24 V / 0.5 A to external relays or contactors. For applications that require power-isolated verification, an integrated relay channel can carry 24 V / 1 A to interrupt the drive enable circuit. These hardware safeguards operate independently of the fieldbus layer, and they provide deterministic response when an emergency stop, light curtain, or guard switch is triggered.
