Product Description:

The CSH01.1C-PB-NNN-NNN-NNN-L1-S-NN-FW control section is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. This module plugs into drive racks to handle drive coordination, local logic, and fieldbus communication for industrial automation cells. Integrated I/O resources and a dedicated Profibus interface let the unit translate machine signals to the drive system so that axes, sensors, and interlocks can be monitored and commanded in real time. Its role is centered on control and communication, making it suitable for applications that require coordinated responses between the drive and external machine devices.

Analog measurement channels are designed with an input impedance of 160 kΩ, and this high value minimizes loading on external transducers. Each analog output can source up to 1 mA at a reference level of 5 V, making it suitable for setpoint generation to external drives or indicators. Internal electronics draw 7.5 W for the control section, while distributed digital lines can supply field devices with a maximum of 1.1 A. Discrete sensing inputs accept 24 V logic at 3 mA, and the corresponding outputs switch 24 V loads up to 0.5 A. This allows direct connection of light curtains, limit switches, and contactors without intermediary relays, which helps keep the control layout straightforward.

On power-up, the module can draw an inrush of 4 A, so upstream supplies must tolerate this brief surge. Fast trigger lines, such as probe or latch inputs, register level changes within 1 µs, which supports precise capture of encoder marker signals and other time-sensitive events. The Profibus port uses RS485 signaling and is presented on a D-Sub 9-pin female connector. The fieldbus electronics consume 2 W from the backplane, while a DC 24 V relay output is rated for 1 A and the starting-lockout acknowledgment line shares the same 24 V / 1 A capacity. The additional L1 logic supply draws 2 W, which keeps essential diagnostics active during main power isolation.
