Product Description:

The CSH01.1C-SE-EN2-NNN-MD1-L2-S-NN-FW is a controller option card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted in an IndraDrive rack, it forms the command layer that links motion algorithms with drive power electronics and connected sensors. Within automated cells, the board converts program calls into synchronized axis commands, manages peripheral I/O, and enforces integrated safety so packaging, handling, or machining equipment can run with precise timing.

In operation, the card exchanges real-time motion data with drives over the SERCOS II fiber ring while accepting an analog command window of ±10 V for velocity or torque setpoints. Internal electronics draw only 7.5 W, simplifying cabinet thermal design. Twelve external digital inputs and eight transistor outputs are routed through on-board terminals, and each output can switch up to 24 VDC, 0.5 A, allowing direct control of contactors or valves. The auxiliary I/O rail may source as much as 1.1 A, enough to power sensors tied to the block. Feedback flexibility is supplied through EnDat 2.1, 1 Vpp, and 5 V TTL encoder channels, all energized by a regulated 5 V feed so a wide range of linear or rotary transducers can be attached.

Startup transients are handled by an inrush limiter that caps demand at 4 A for a pulse not exceeding 100 ms, protecting upstream supplies. Once energized, the board’s integrated Safe Torque Off circuit removes drive enable lines through a dedicated D-Sub 9-pin female STO connector, letting machines meet Category 3 PL d requirements without extra relays. For programmable sequencing, a RS232 service port is provided, and cable runs up to 15 m are permitted for parameter access from a laptop or HMI. When higher-current signaling is required, a Form A relay contact rated at 24 VDC, 1 A offers galvanic isolation for status lamps or interlocks.
