Product Description:
The CSH02.1B-CC-EC-ET-S4-DA-NN-FW is a motion logic controller produced by Bosch Rexroth Indramat in the CSH Advanced Controllers series. It coordinates multiple drive axes and peripheral I/O in distributed factory lines, delivering real-time command execution for servo drives, sensors, and integrated safety circuits. By combining Ethernet and encoder interfaces, the unit serves as the central processing element of an IndraMotion system, synchronizing motion profiles, gathering feedback, and relaying status data to supervisory PLCs. This arrangement allows the controller to manage axis communication and machine responses from a single control platform.
The controller draws its logic power from a DC 24 V supply and consumes a base load of 17 W, allowing compact power supplies to feed the rack. Option boards raise consumption slightly; the encoder extension adds 1.1 W and the Ethernet interface adds 2.7 W, while the available encoder power remains limited to 6 W in total. Two separate encoder rails provide 500 mA at 12 V and the same current at 5 V for SSI or EnDat devices. For process signals, the unit provides 5 analog input channels with 12-bit resolution and 4 analog output channels for reference generation. Network coordination of multiple axis drives is handled by the integrated Sercos III master, which exchanges cyclic data in real time without requiring separate user-managed communication handling.
Discrete control capability is provided by 24 digital input channels that accept 24 V signaling and 13 digital output channels that switch actuators or signal relays. Each relay stage can conduct up to 1000 mA, which supports pilot valves and contactors connected directly to the board. Functional safety is handled through Safe Motion. The safety option consumes 2.5 W, and safe torque-off commands are transmitted over the existing Sercos bus, so no separate safety wiring is needed for that function. Resolver feedback is not supported, so applications that use resolver transducers require compatible encoder feedback instead.
