Product Description:

The CSH01.1C-NN-NNN-NNN-MD1-NN-S-NN-FW is a control section module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive drive stack, it supervises axis motion, processes feedback, and interfaces field signals. It forms the computational core that links servo power stages with higher-level PLCs in automated machinery. This arrangement lets one module coordinate command handling and local I/O within the same drive assembly.

Operating from a regulated 24 V DC logic rail, the card consumes 7.5 W, so it can be powered from small cabinet supplies. The analog input channel supports dynamic processes up to 1.4 kHz, and its 160 kΩ input resistance helps preserve signal accuracy by minimizing sensor loading. Outgoing reference signals are produced with a resolution of 19.5 mV/inc, can source 1 mA, and reach a maximum swing of 5 V into loads down to 5 kΩ. Twelve MD1 digital inputs accept limit switches or proximity flags, while eight MD1 digital outputs provide command lines for actuators that stay within the available group current. The inrush limiter and low steady draw help maintain stable control-power distribution on multi-axis installations where several modules share one cabinet supply.

During energization, an inrush limiter restricts the module to 4 A for 100 ms, protecting upstream converters. Each MD1 output can switch up to 500 mA, and the eight-channel block must remain below a total of 1000 mA when driving relays or solenoids. A separate relay stage carries 1 A continuously, and its mechanical contacts are rated for a life of 1 × 10⁸ cycles, which suits frequent switching duties. This output structure allows the controller to handle discrete field devices, manage transient conditions, and isolate relay-driven functions without external interposing hardware.
