Product Description:

The Bosch Rexroth Indramat CSH01.2C-C0-EN2-EN1-CCD-S1-S-NN-FW belongs to the CSH Advanced Controllers series. It functions as a central motion-control unit for IndraDrive systems. It executes axis commands, exchanges real-time data with higher-level PLCs, and supervises safety I/O, integrating drive regulation and fieldbus communication in one slot-mounted module for industrial automation lines.

The controller draws a steady 8.5 W of base power, setting the thermal load that an enclosure must remove during continuous operation. At power-up, the electronics experience a 4 A inrush current, so upstream supplies and fusing must tolerate that short surge. A programmable watchdog can generate output pulses up to 100 ms, allowing transient enable signals to external contactors. The CCD network port supports 100Base-TX Ethernet traffic that conforms to the IEEE 802.3 standard; the link consumes only 1 W and is presented on an RJ-45, 8-pin connector for standard patch cables. An additional RS-232 serial interface is provided for service access and parameter transfer. Each optional encoder channel, EN1 and EN2, is powered locally; the first channel dissipates 6 W from an 8 V rail, while the second draws 6 W from a separate 5 V source, isolating feedback power from logic supplies.

Safety circuits are energized by a 24 V DC feed that can supply up to 1.6 A, with all contacts routed through a D-Sub 9-pin plug to simplify field wiring. For interlocking functions, the internal relay is rated at 24 V DC, 1 A, providing a direct path to motor contactors or gate switches. The hardware watchdog powering EN1 accepts an 8 V input, so sensor power remains separate from the safety bus. These interface and supply details show how auxiliary loads are partitioned across the backplane.
