Product Description:

The CSH02.1B-CC-EC-CN-S5-EC-NN-FW is an automation control card manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Acting as the central processing unit in modular drive systems, the card coordinates servo axes, manages fieldbus traffic, and executes user programs to synchronize motion in industrial machinery. It installs directly beside Rexroth power modules, minimizes cabinet depth, and delivers deterministic cycle times for packaging, assembly, and material-handling equipment. By combining motion control and communication functions in one unit, it supports coordinated machine sequences such as indexing, transfer, and positioning without requiring a separate standalone controller.

At the hardware level, the controller offers 11 digital inputs for fast signal acquisition, allowing direct wiring of limit switches, sensors, or interlock contacts. For continuously varying process variables, it provides 3 analog inputs, and it can drive field devices through 2 analog outputs. Five of the digital terminals are user-selectable as outputs, which adds flexibility when assigning machine status and control signals. The module draws its logic power from a 24 V DC supply, and its base consumption of 17 W helps keep thermal load low in compact cabinets. Inrush is limited to less than 5 A, which reduces stress on the upstream supply during power-up. Two probe inputs support precise edge capture, and three optional slots allow the controller to be adapted for additional interfaces or I/O functions.

In networked applications, the secondary CANopen interface can manage up to 127 slave nodes, while primary communication with drives and distributed I/O occurs through the SERCOS III master channel. This arrangement allows the controller to exchange cyclic motion data with the drive system while also supervising peripheral devices on a separate network. Deterministic encoder data arrive through both primary and auxiliary multi-encoder ports, which supports synchronized control loops and reference capture from more than one source. Motion functions are certified under the Safe Motion package, allowing compliance with SIL and PL safety levels without separate external hardware. The time-stamping function supports captured pulses up to 1 ms in width, which is useful for print-mark registration and other timing-sensitive machine operations.
