Product Description:

The Bosch Rexroth Indramat CSH01.1C-SE-NNN-MA1-MD2-L1-S-NN-FW controller is part of the CSH Advanced Controllers series. It is intended to act as the motion and I/O coordinator inside automated machinery where multiple servo axes, sensors, and safety channels must be supervised in real time. By combining field communication and local signal conditioning, the unit supplies a deterministic command layer between electrical drives and a plant-level PLC, enabling repeatable positioning, speed regulation, and sequence control on assembly lines, packaging equipment, and similar automated systems.

For deterministic drive networking, the controller uses SERCOS II and supports a ring speed of 16 MBaud, allowing tight control cycles for synchronized motion. The integrated MA1 board provides 2 Differential Inputs that accept ±10 V references and two matched outputs. Each analog output can source up to 10 mA, so external buffer amplifiers are usually unnecessary. The MD2 expansion adds 16 digital inputs that read 24 V proximity switches or fault contacts through opto-isolated channels, helping keep field disturbances out of the controller logic.

Complementing these inputs, the MD2 section features sinking transistor stages that deliver 0.5 A per channel, letting the module energize contactors, solenoids, or status lamps directly. An onboard digital-to-analog converter furnishes a reference level of 5 V at 1 mA for sensor excitation or test points. Functional safety is supported by the built-in circuit for Starting Lockout, which disables drive enable signals until the monitored safety chain reaches the required state. Configuration and service tasks are performed over the RS232 serial interface, while a dedicated D-Sub connector routes the 24 V / 1 A relay output and accepts the 24 V / 3 mA safety input.
