Product Description:

The CSH01.1C-NN-ENS-ENS-NNN-NN-S-NN-FW control section is manufactured by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It is installed in IndraDrive platforms where it executes motion commands, processes field signals, and coordinates servo axes. By combining analog, digital, and encoder channels on a compact board, the module serves as the central processing element in industrial automation cells, synchronizing drives with PLC sequences and real-time feedback loops.

In the signal conditioning layer, the board accepts an analog input span of ±10 V; the ± polarity allows bipolar feedback such as torque or velocity references. The input presents 160 kΩ of resistance so transducers are not heavily loaded. Command outputs occupy a separate channel that delivers a range of 0 to +5 V while sourcing 1 mA through loads down to 5 kΩ; this suits drive enable or trim circuits. Digital inputs switch to the ON state at 15 V, guaranteeing noise immunity on long cable runs, and the digital output stage can source 500 mA for contactors or status lamps. During continuous operation the controller draws only 19.5 W, limiting cabinet heat rise in multi-axis racks.

Feedback and timing functions are handled by two ENS encoder ports that supply 11.6 VDC at 500 mA in total; the regulated rail keeps incremental or absolute sensors within tolerance. The encoder supply line is protected against high demand by an inrush limiter that caps startup draw to 4 A. For event capture the probe channel accommodates pulses as short as 4 µs, and the controller can stretch an acknowledge pulse to a maximum width of 100 ms for downstream logic. A relay contact rated at 24 VDC, 1 A provides galvanically isolated signaling to safety relays even though dedicated safety technology is not present.
