Product Description:

The CSH01.1C-PL-EN1-MEM-MA1-S1-S-NN-FW is an axis and machine controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. As a compact control card, it plugs into Rexroth drive racks and coordinates position, speed, and auxiliary machine functions over fieldbus and discrete lines. In automated cells, it serves as the command layer that links feedback devices with power stages, so one module can sequence motion, monitor operating states, and exchange status with higher-level PLCs. This format suits machines that need centralized control inside a drive-based architecture without adding a separate standalone controller.

It provides 2 analog input channels that accept a ±10 V input range, allowing direct connection of potentiometers or process transmitters without additional scaling circuits. Each input is digitized at 12-bit resolution, giving 4,096 steps for fine parameter adjustment. The module also has two analog outputs with the same voltage swing for drive reference or actuator control. Internal consumption is limited to a 7.5 W base power draw, which helps keep cabinet heat low during normal operation. At power-up, the module can draw a 4 A inrush current for up to 100 ms, so the supply path must tolerate a brief startup surge. A dedicated 8 V DC rail powers HSF encoders, while resolver feedback is excited with 18.2 Vpp at 4 kHz to maintain stable signal transmission.

It handles high-density parallel I/O through 16 digital inputs and 16 digital outputs, allowing the controller to read sensors and switch external devices without extra interface cards. These connections can be used for tasks such as reading limit signals, monitoring interlocks, and operating relay-based machine functions. Each safety output can source 0.5 A, which supports direct actuation of contactors in emergency stop chains. For serial diagnostics, the port reaches 115 kBaud RS-232, while absolute position data are streamed over an SSI channel clocked at 1 MHz SSI clock. The resolver and encoder supply circuits operate continuously after the brief startup surge has settled.
