Product Description:

The CSH01.1C-PL-ENS-EN1-MA1-S2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for its CSH Advanced Controllers series. Installed in IndraDrive modular drive stacks, it hosts the processing and field-level interfaces that coordinate servo axes, discrete sensors, and machine safety logic in automated lines and cells. By combining motion command generation with real-time feedback acquisition, the unit supplies the deterministic control backbone required for packaging, material handling, and general industrial equipment. It is suited for applications that need coordinated axis control alongside local analog and digital signal handling.

On the power side, the unit draws only 7.5 W, minimizing cabinet heat. The EN1 high-speed feedback connector provides an 8 VDC excitation rail able to source 250 mA, then superimposes an 18.2 Vpp carrier at 4 kHz to energize resolver transducers that return absolute rotor position. The ENS encoder input is stabilized at 11.6 VDC for digital encoders. Analog conditioning is handled by the MA1 module, which offers two input and two output channels, each spanning ±10 V for velocity or torque references. The controller also exposes 16 parallel inputs and 16 parallel outputs so that fast on/off signals can bypass a fieldbus when cycle time is critical.

For machine interlocks, the safety block sources 24 VDC logic and can switch field devices through a solid-state path rated at 0.5 A. The available supply budget of 500 mA lets the module power guard switches, light curtains, and other safety sensors without an auxiliary supply. Relay contacts on the general I/O side operate at the same 24 V level and are rated at 1 A, permitting direct actuation of pneumatic valve coils and control relays. This arrangement lets the controller handle both motion data and discrete control from a single slot while reducing panel space and wiring complexity.
