Product Description:

The CSH01.1C-S3-ENS-EN2-MA1-S1-S-NN-FW is a motion-logic controller card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted inside an IndraDrive modular rack, the unit coordinates servo axes, gathers feedback, and issues deterministic real-time commands to drives and I/O nodes in automated machinery. By combining high-speed communication with onboard signal conditioning, the product serves as the central control layer for packaging lines, material-handling gantries, and other multi-axis industrial systems. It fits the manufacturer's drive topology, which helps reduce wiring and simplify cabinet design.

Primary fieldbus exchange occurs through SERCOS III, giving the controller a 100 Mbit/s cyclic channel for position, torque, and diagnostic data. Two encoder sockets support IndraDyn/Hiperface/1 Vpp/TTL feedback or EnDat 2.1 / 1 Vpp / TTL, allowing mixed incremental and absolute transducers on the same axis group. Service laptops connect over an RS-232 service port. During startup, the supply draws 4 A of inrush current for a 100 ms pulse before stabilizing at a continuous 7.5 W power draw, which permits fan-free cooling in most cabinets. Master logic voltages enter through the S1 terminal strip, and the board conditions internal rails to drive the signal processors and communication ASICs.

The controller measures 241 mm high, 49.5 mm wide, and 103 mm deep, so it occupies a single slot beside the power section. The MA1 option card provides 2 differential analog inputs, 2 analog outputs, and 12-bit resolution for each channel, enabling current or voltage reference signals for third-party sensors and actuators. Safety and interlock wiring uses the S1 interface: the input channel tolerates 24 V / 3 mA, the transistorized output can source 24 V / 0.5 A, and an onboard relay is rated at DC 24 V / 1 A for external contactors. The module can distribute low-power control signals without additional terminal blocks or relays.
