Product Description:

The CSH01.1C-SE-ENS-NNN-MD1-L1-S-K1-FW is an axis and logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Serving as the interface between higher-level PLC instructions and servo drives, it interprets motion commands, processes sensor feedback, and issues synchronized setpoints in real time. This role places the device at the core of packaging machines, pick-and-place cells, and material-handling stations where coordinated movement and deterministic task sequencing are required. By combining motion control and logic handling in one platform, it can coordinate machine events and axis responses through the same control structure.

The controller accommodates two differential analog inputs that present an input resistance of 160 kΩ, allowing sensors to connect without loading their output stages. Each channel is digitized with a resolution of 1.23 mV/inc, so low-level variables can be captured with fine granularity. On the output side, the board drives signals into loads down to 5 kΩ, and its digital-to-analog converter steps them in 19.5 mV/inc increments. Internal electronics draw 7.5 W during operation, which helps limit heat buildup inside the cabinet. When mains power is applied, an inrush limiter restricts the surge to 4 A for 100 ms, reducing stress on upstream protection devices. Additional encoder resources include 120 Ω of input termination to help maintain signal integrity on connected cables.

Field connectivity is expanded by 12 digital inputs and eight sourcing outputs, giving the controller direct links to switches, sensors, and small actuators. Motion acknowledgment is handled by a dedicated supply of 24 V / 1 A, while the lockout control line draws 24 V at 3 mA to satisfy safety circuits. Quadrature feedback devices receive up to 500 mA from the integrated 11.6 V encoder rail, eliminating the need for an external encoder power supply in many installations. High-speed command latching is supported through a TTL capture port rated for 400 kHz, which allows precise timing of fast input events. This is useful where short pulses from markers, registration sensors, or index signals must be captured without timing drift.
