Product Description:

The CSH01.1C-PB-EN2-NNN-MA1-S1-S-NN-FW belongs to the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. It is a compact control section intended for drive-based automation where motion commands, feedback signals, and fieldbus traffic must be consolidated inside a single module. Within an installation, it links servo drives to higher-level PLCs, reads encoder data, and exchanges analog process variables so that coordinated positioning and speed regulation can be achieved across multiple machine axes.

This control section provides 2 differential analog input channels that accept voltage or current signals; each input is digitized with 12 bits of resolution, allowing 4096 discrete values for fine set-point acquisition. For actuator tasks it offers 2 analog outputs that also operate at 12-bit depth, giving equally granular command signals to external converters or indicators. Field-level communication is handled through PROFIBUS; telegrams are routed over the integrated D-Sub connector and follow RS485 signaling so long cable runs remain immune to noise. Position feedback is supported through the multifunction encoder interface specified as EnDat 2.1 / 1 Vpp / 5 V TTL, letting the module decode absolute or incremental signals without additional hardware.

The encoder input is protected by a line impedance of 35 ohms, while its sensor supply can deliver up to 350 mA at the regulated 5 V rail, enough for resolvers and multiturn encoders with internal electronics. Remote engineering is possible over an Ethernet service port that reaches a length of 100 m with standard Category 5e cabling; the link uses the industrial 100Base-TX protocol and is terminated on an RJ-45, 8-pin jack. Additional configuration can be performed with an RS-232 channel operating at 115 kBaud, and discrete safety monitoring is available through the integrated Safety Technology I/O option, enabling drive-based shutdown functions without external relays.
