Product Description:

The CSH01.1C-SE-ENS-EN1-MD1-L2-S-XP-FW is a motion and I/O expansion controller from Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed on the front of a Rexroth drive, it executes axis interpolation, gathers field signals, and forwards real-time status to cell-level control. By combining communication, logic, and safety on a compact daughterboard, the unit reduces panel space and wiring tasks in automated printing lines, packaging machines, and material-handling stations.

Axis commands are exchanged over SERCOS II, and the optical interface can be clocked at up to 16 MBaud so servo feedback and drive parameters reach the controller within microseconds. The analog monitor channel presents a high impedance of 160 kΩ, allowing sensors to share lines without loading their source. A single proportional output delivers up to 1 mA, supporting valve positioners or transducer excitation. Digital logic is processed through 24 V inputs that draw only 3 mA and through outputs rated for 24 V / 0.5 A, enabling direct actuation of contactors or indicator lamps without external relays. Twelve additional inputs and eight outputs are provided on the MD1 extension, while the base card supplies 11 inputs and 4 outputs for local machine signals.

Core electronics draw only 7.5 W, so enclosure ventilation typically suffices; however, at power-up the module can pull 4 A for a maximum of 100 ms, and supply lines must be sized accordingly. Functional safety is integrated through Safe Torque Off, which removes drive power via hardware gating when an emergency circuit opens. Auxiliary rails of 8 V for EN1 encoders and 12 V for ENS sensors are generated on board, eliminating separate power packs. For commissioning or diagnostic scripts, a serial port supports data exchange at up to 115 kBaud. The controller maintains relay contacts rated 24 V / 1 A for field isolation and preserves signal integrity by restricting analog output noise.
