Product Description:
The CSH01.1C-PB-EN2-EN1-NNN-NN-S-NN-FW is a drive controller master module manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It occupies one slot in a modular Rexroth inverter stack and provides signal conditioning, processing, and fieldbus access for multi-axis motion packages. The module links drives to higher-level PLCs or SCADA hosts, filters analog setpoints, and issues digital control pulses for velocity or position loops in industrial automation cells. It is intended for coordinated machine control where several axes share a common hardware platform.
The module interfaces with the plant network through a PROFIBUS master channel presented on a D-Sub 9-pin female connector for daisy-chain wiring. Its analog command port offers an input resistance of 160 kΩ, which limits current draw from external transducers and helps protect delicate sensors. Digital output stages can sink or source up to 0.5 A per channel, allowing direct control of relays or optical isolators. Internal electronics dissipate only 7.5 W during nominal operation, so cabinet ventilation requirements remain low. The front panel has a height of 241 mm, matching the standard Rexroth book-size frame and aligning with companion power sections.
The housing depth is 49.5 mm, so the assembly fits shallow control enclosures while still accommodating bus couplers and encoder sockets. A power-on inrush of 4 A is specified, which helps determine fuse selection and soft-start sequencing. The EnDat feedback channel supplies up to 350 mA at 5 V for absolute encoders, while the relay output path is rated for 24 VDC / 1 A to switch brakes or contactors. Additional connections support EnDat 2.1, 1 Vpp, TTL, HSF, and RSF sensors, and the board receives an 8 V bus from the drive stack to support those encoder options without an external supply. These feedback options let the controller work with several common encoder signal formats.
