Product Description:
The CSH01.1C-ET-ENS-EN1-NNN-NN-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It is an embedded motion controller that plugs into an IndraDrive power section and manages real-time interpolation, axis supervision, and network communication for industrial robots, printing lines, and material-handling stations. By integrating analog, digital, and serial channels with a dedicated processor, the module closes control loops locally while exchanging status frames with supervisory systems over deterministic Ethernet.
An analog input resistance of 160 kΩ ensures that sensors connected to the differential channels do not place a heavy load on their source circuits. The digital input block accepts 24 V / 3 mA signals, giving PLC-compatible logic levels for limit switches and probes. For outbound positioning commands, the analog output can drive loads down to 5 kΩ without distortion. Multi-protocol operation through PROFINET, EtherNet/IP, SERCOS III, and EtherCAT is available on a single Multi-Ethernet port, simplifying plant integration. Internal electronics draw just 7.5 W at standby, so cabinet heat buildup remains low even when several controllers share the same rail. Encoder Interface 1 supports IndraDyn, HIPERFACE, and 1 Vpp feedback formats, while the RS-232 service port supports local diagnostics and setup.
The I/O backplane can source up to 1.1 A for external sensors, and protection components limit start-up demand to an inrush of 4 A to avoid tripping supply breakers. High-speed measurement tasks benefit from a probe response time of 1 µs, and edge-triggered capture supports pulse widths up to 100 ms. Safety relays inside the card switch loads up to 24 VDC / 1 A, allowing direct control of contactors or brake solenoids. Additional resources include an 8 V resolver supply, dual-channel HSF feedback support, and digital outputs rated at 24 V / 0.5 A for lamp stacks or pneumatic valves.
