Product Description:

The CSH02.1B-ET-EC-EC-S4-EM-NN-FW is a control section produced by Bosch Rexroth Indramat in the CSH Advanced Controllers series. It acts as the central processor for IndraDrive-based automation, translating PLC instructions into synchronized motion commands and handling local I/O tasks for conveyors, pick-and-place axes, packaging stations, and similar equipment in coordinated machine sequences. By embedding logic, axis coordination, and parameter storage in one compact housing, the device simplifies cabinet layouts while keeping local control and motion functions in one place.

The module operates from a DC 24 V service supply and draws only 17 W, so heat generation remains low during normal operation. Three analog inputs and two analog outputs can connect pressure sensors or valve amplifiers, while eleven digital inputs plus five configurable DIO points capture fast limit signals or work as outputs in automated process equipment. The A/D section handles loads up to 100 nF, and the D/A channels require at least 2 kΩ to maintain linear output behavior. Each analog output refreshes within a 750 µs window, and encoder emulation remains reliable up to 40 m with shielded wire or 30 m if unshielded.

Network integration is handled by the Multi-Ethernet backplane, which simultaneously accepts EtherCAT, EtherNet/IP, PROFINET IO, and sercos III traffic without extra option cards. Two Multi-Encoder, 1 Emulation feedback ports close the loop with Heidenhain, EnDat, or incremental sources, while a simulated encoder stream can be forwarded to auxiliary drives or monitoring devices. Drive-integrated Safe Motion functions support SIL 3 stop, limited speed, and direction monitoring when paired with certified motors, which can reduce the need for discrete safety contactors in suitable systems. These communication and feedback resources let the controller synchronize multiple axes and exchange real-time data with higher-level PLCs across mixed Ethernet topologies during continuous operation.
