Product Description:

The CSH01.1C-PL-ENS-EN2-NNN-L1-S-NN-FW is a motion-control logic module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It serves as the central processing card inside an IndraDrive power section, issuing position commands, reading encoder data, and coordinating peripheral digital I/O. In industrial automation, the module links higher-level PLC instructions with real-time servo regulation so that packaging machines, presses, and material-handling stations can run repeatable cycles with deterministic timing and coordinated axis response.

Its base power consumption is 7.5 W, which keeps thermal dissipation low during standby and supports compact fanless cabinets. Command and status bits are exchanged through a Parallel Interface, and the board supports sixteen discrete inputs and sixteen discrete outputs for local sensors, interlocks, and actuator signals. The secondary encoder channel labeled EN2 draws 350 mA from a regulated 5.0 VDC rail, giving the controller enough margin to power TTL differential encoders without an external supply. When the module is energized, an inrush limiter caps the surge to 4 A, which helps protect upstream circuit breakers and reduces voltage sag on shared 24 V buses. A Mini-DIN 8-pin female connector provides RS-232 access for setup and service communication.

The additional encoder supply ENS delivers 500 mA at 11.6 VDC, allowing support for resolvers or hall-sensor hybrids on mixed-feedback axes. Motion can be halted using the integrated starting lockout, and the hardware meets the requirement for Stop Category 0, where power is removed immediately without a controlled ramp-down. The lockout circuitry reacts to 24 V input commands at only 3 mA and passes a 24 VDC / 1 A acknowledgment signal to downstream relays. To reject contact bounce, the acknowledgment pulse is limited to a maximum width of 100 ms.
