Product Description:

The CSH01.1C-PB-EN2-EN2-CCD-S1-S-NN-FW is a motion control hardware module produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed for multi-axis automation, the unit coordinates servo drives, collects encoder feedback, and exchanges field data with higher-level PLCs. It combines motion communication and safety-related I/O in one housing, which helps reduce panel complexity in production lines and material-handling equipment. Its control role suits applications where synchronized axis operation and reliable network exchange must occur at the same time.

At the logic level, the controller draws just 7.5 W, which helps limit heat inside compact enclosures. Machine data are exchanged over the integrated PROFIBUS-DP port, while real-time axis communication is handled by its SERCOS III Master function using IEEE 802.3 Ethernet signaling. Parameterization and diagnostics use a separate 100Base-TX engineering port, which keeps service traffic apart from process communication. The encoder input supports EnDat 2.1, 1 Vpp, and 5 V TTL feedback formats, accepts a minimum load of 35 Ω, and provides 5.0 V at 350 mA for sensor power. Shielded sense lines may be routed up to 75 m without boosters when the installation stays within the stated electrical limits.

For service access, the module includes an RS-232 port that supports text-based commands at up to 115 kBaud, with cable length limited to 15 m. The transistorized digital outputs are rated for a combined 500 mA, which suits contactors and opto-isolated relays used for discrete control. A nine-pin female D-Sub carries fail-safe signals, including 24 V/3 mA inputs and 24 V/0.5 A outputs for safety loops. The serial port and discrete I/O are built into the same module, so these connections remain on the controller housing instead of requiring separate interface hardware.
