CSH01.1C-PB-EN1-MA1-MD2-L1-S-NN-FW

The CSH01.1C-PB-EN1-MA1-MD2-L1-S-NN-FW is a motion-logic controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The module combines axis coordination and programmable logic in a single card that plugs into IndraDrive power sections, so decentralized drive systems can execute positioning tasks without burdening the central PLC. In conveyor, packaging, and assembly lines it converts high-level machine commands into synchronized setpoints for multiple servos, ensuring consistent timing between motors, sensors, and actuators. Its integrated fieldbus master and local I/O reduce the need for separate processors and communication cards.

Two analog input channels accept signals across an operating span of ±10 V, letting potentiometer references or transducer voltages be read without external scaling. Each sample is digitized with 12 bits of resolution, equating to 4096 steps and supporting precise closed-loop control. Altogether, 2 configurable analog inputs and their corresponding outputs can be parameterized for unipolar or bipolar ranges. Discrete feedback is captured by 16 digital inputs that latch state changes on every communication cycle. The controller’s electronics operate from a stabilized 24 VDC line, and a typical inrush draw of 4 A must be considered when selecting supply protection.

Complementing those resources, the board provides two analog outputs and sixteen digital drivers for actuator control, keeping wiring short when the controller is mounted beside the drive. Field communication is handled through the integrated PROFIBUS-DP master, and network cabling attaches to a D-Sub 9 female connector that follows standard pin assignments. Under steady load the logic circuitry consumes only 7.5 W, easing thermal design in densely packed cabinets. A brief power-up surge of 4 A still occurs, so designers allocate surge headroom on the 24 VDC rail when several controllers start simultaneously.
