Product Description:

The CSH01.1C-CO-EN1-EN2-MA1-NN-S-NN-FW is a motion control card engineered by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Acting as the central processing and I/O extension inside IndraDrive stacks, the module establishes deterministic communication with higher-level PLCs and executes axis functions that synchronize servo drives in automated machinery. Its design integrates incremental encoder conditioning and analog process channels so a single card can handle position feedback, fieldbus communication, and low-level signal interfacing required in multi-axis industrial automation cells.

The quiescent consumption is 7.5 W, allowing low-voltage supplies to be sized with only a small thermal allowance. During power-up, an inrush limiter restricts current to 4 A, and the surge lasts no longer than 100 ms, so upstream fuses and breakers can be sized accordingly. The card supports controller area networks through the CANopen / DeviceNet interface, enabling cyclic data exchange without extra communication hardware. Each digital input recognizes a logical high at 24 V, 3 mA, while the two built-in analog outputs generate setpoints with 8-bit resolution and can source up to 1 mA for external circuitry.

The MA1 mezzanine portion adds 2 differential analog inputs and 2 single-ended analog outputs, and it converts incoming process signals with 12-bit resolution while the output channels provide matching command resolution. Encoder supply EN1 provides a regulated 8 V reference for incremental sensors, whereas EN2 offers a separate 5.0 V rail that can deliver 350 mA when the connected transducer impedance is at least 35 Ω. For discrete power switching, an onboard relay is rated at DC 24 V, 1 A, allowing the control card to actuate brakes or contactors directly without an interposing driver stage.
