Product Description:

The CSH01.1C-PB-ENS-NNN-MA1-L2-S-NN-FW is a motion-control processor produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside an IndraDrive cabinet, the module coordinates axis positioning, reads field signals, and forwards commands to power inverters. This makes it a central element in automated packaging, printing, or material-handling lines.

The controller exchanges cyclic data with higher-level PLCs through PROFIBUS, so parameter sets and diagnostics travel on a deterministic bus. One base analog input accepts signals up to ±10 V, and its 160 kΩ impedance minimizes loading on external sensors. Two base analog outputs deliver reference levels of 5 V / 1 mA for actuator setpoints or panel meters. Internal electronics require only 7.5 W, which simplifies cabinet cooling and accommodates uninterruptible power supplies with modest ratings. When DC power is first applied, the unit draws an inrush of 4 A, and upstream breakers and wiring must tolerate this short surge without nuisance trips. An encoder interface supports IndraDyn, HIPERFACE, 1 Vpp, and TTL feedback, allowing the same controller to read resolvers or high-resolution optical encoders without adapter cards. The MA1 expansion adds two differential inputs and two outputs so additional load cells or pressure sensors can be connected without external signal conditioners.

A separate digital I/O rail operates on DC 19...30 V at up to 1.1 A, letting proximity switches and photo-eyes share a common supply directly from the controller. Safety is handled by a dedicated channel that executes Safe Torque Off; when triggered, drive power is removed in under the specified 100 ms pulse width. The function is certified to SIL 3 / Cat. 3 PL e, permitting its use in machinery that must meet the highest stop categories. Mechanical integration is straightforward because the housing measures 241 × 49.5 × 103 mm, allowing two units to fit side by side on 50 mm DIN rail spacing while still leaving room for the 9-pin D-Sub STO connector and other field terminations.
