Product Description:

The CSH01.1C-S3-EN2-NNN-MA1-L2-S-NN-FW is an automation controller manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It is typically installed in multi-axis drive cabinets used in automated machinery. There, it executes motion profiles, processes machine feedback, and distributes synchronized commands to servo inverters and peripheral hardware through its integrated communication and encoder interfaces.

The main control bus uses SERCOS III for deterministic real-time data exchange, and standard plant networking is handled through a 100Base-TX Ethernet port that terminates on an RJ-45 8-pin connector for integration with supervisory equipment. Two differential analog input channels and two analog output channels are routed to a D-Sub 15-pin header, and each channel is digitized or generated with 12 bits of resolution. Discrete actuators can be driven directly because the digital outputs are rated at 24 V, 0.5 A. All field I/O draws from an internal supply that may deliver up to 1.1 A, so downstream device loading must stay within that limit. A front-panel RS232 port supports local service access, and an additional D-Sub 9-pin connector is reserved for the safety circuit.

The safety layer implements Safe Torque Off, enabling the controller to remove motor power without affecting the application program. For position feedback, the board accepts an EnDat 2.1 interface at an analog carrier level of 1 Vpp and a differential clock and position track at 5 V TTL. A regulated 5 V encoder supply is provided on the same header for connected feedback devices. The two extension analog inputs allow sensor signals such as load cells or speed probes to be measured directly, while the paired analog outputs can transmit setpoints to external drives or valves. Final wiring to limit switches, emergency stops, and light curtains passes through the dedicated D-Sub safety connector, keeping functional and safety-related circuits clearly separated.
