Product Description:

The CSH01.1C-ET-ENS-EN2-NNN-L2-S-NN-FW is a drive and I/O control card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive power sections, the module processes encoder feedback, distributes control signals, and supports the Safe Torque Off safety channel. Within an automation cell, it coordinates motion axes, fieldbus traffic, and protective interlocks, acting as the core logic element that links individual servo amplifiers with a supervisory PLC.

Its electrical front end draws a base standby load of 7.5 W, limiting cabinet heat while retaining diagnostics. The analog measurement channel offers an input impedance of 160 kOhm, so connected sensors place negligible load on upstream transducers. For networked motion, the board exposes a Multi-Ethernet interface that uses the 100Base-TX physical layer, and deterministic traffic shares links with standard TCP/IP without extra hardware. Power-up stress on the supply is contained by an inrush current of 4 A that decays after a pulse width of 100 ms. Maintenance access through the RS-232 port is possible up to 15 m. The integrated Safe Torque Off circuit removes drive-enable paths during an emergency stop sequence.

The controller distributes field signals through several discrete channels. A primary digital line can source 24 V at 0.5 A, which is sufficient for solid-state relays or optical couplers. Encoder port EN2 delivers 5.0 V at 350 mA and tolerates a line load of 35 ohms, maintaining clean feedback even with extended cables. The secondary encoder rail ENS provides 11.6 V at 500 mA and accepts TTL edge rates up to 400 kHz for high-resolution incremental sensors. A separate relay contact rated at DC 24 V and 1 A is available for drive-ready signaling to external interlock circuits, allowing the card to furnish power, logic, and safety functions from a single platform.
