Product Description:

The CSH01.2C-PL-ENS-ENS-CCD-S1-S-NN-FW control section is manufactured by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Within modular Rexroth drive racks, the unit manages axis commands, converts sensor feedback, and supervises integrated safety so that inverter stages can follow real-time motion profiles in automated machinery. Conventional field wiring is handled on the parallel interface, which offers bidirectional 16-bit control lines so a PLC can latch or read status bits without protocol overhead.

During operation the card draws a basic load of 8.5 W, keeping internal thermal rise low while the analog input accepts a symmetrical range of ±10 V for external speed or torque references. Two optical CCD ports, X24 and X25, follow the IEEE 802.3 signaling rules, allowing deterministic communication with other drive sections over Ethernet-based cross-communication where this board assumes the master role. Sixteen transistor outputs can source up to 500 mA in total. Parameter data is downloaded through the engineering interface, which supports 100Base-TX on a shielded 8-pin RJ-45 connector.

For closed-loop positioning, two ENS feedback slots accept encoder modules, each supplied with 11.6 VDC at up to 500 mA, while a peak startup draw of 4 A covers capacitor charging when the rack is energized. Discrete machine signals enter through the parallel digital I/O block that provides 16 In / 16 Out channels, and emergency circuits are wired to the X41 D-Sub 9 female safety connector. All safety reactions are processed locally by the S1 Safety I/O logic so drive-enable lines can be interrupted within the permitted response time. The controller can distribute synchronized setpoints, relay encoder data, and perform STO or SS1 actions across multiple axes without additional interface cards.
