Product Description:

The CSH01.1C-S3-EN2-NNN-S2-S-NN-FW is an axis and I/O controller from Bosch Rexroth Indramat’s CSH Advanced Controllers series. It is mounted in drive cabinets to coordinate motion profiles and peripheral signaling for automated equipment. Real-time communication is handled over SERCOS III industrial Ethernet, allowing the controller to exchange operating data with higher-level PLCs through the network.

An analog channel delivers a maximum current of 1 mA and up to 5 V, allowing proportional setpoints to be sent to external amplifiers without heavily loading the source electronics. For discrete tasks, the digital outputs can source 500 mA each, with a combined limit of 1000 mA across the full bank. That arrangement supports contactors, lamps, and other field devices while keeping total output demand within the controller’s rated capacity.

The feedback interface supports the EN2 (EnDat 2.1/1 Vpp/5 V TTL) interface and cable lengths up to 75 m, which helps when encoders are mounted away from the cabinet. Startup demand peaks at 4 A for 100 ms, reducing sudden stress on protective devices during power-up. Continuous power consumption is only 7.5 W, making thermal planning easier in compact enclosures with several adjacent control components.

Wake Industrial can arrange same-day shipping when deadlines are tight. International shipping options are available for global sites, and quotations remain valid for 30 days to support purchasing schedules. The chat tool available on the website can be used for general questions about type codes or fault codes before ordering. Stock availability can also reduce downtime when a replacement controller is needed quickly for a stopped axis or an urgent onsite maintenance project.
