Product Description:

The CSH01.1C-NN-ENS-MEM-MA1-S1-S-NN-FW is a single-axis controller plug-in from Bosch Rexroth Indramat in the CSH Advanced Controllers series. Installed in IndraDrive power sections, it executes motion sequences, evaluates encoder feedback, and drives digital outputs for actuators or relays used in industrial automation cells. Through this modular card, a machine builder can integrate position control, device supervision, and field communication without adding external stand-alone processors.

The electronics are powered from a control supply of 24 V DC, a level that aligns with common cabinet auxiliaries and lets the logic remain active during main power cycles. Internal loss is limited to 7.5 W, so heat dissipation demands are modest and convection cooling inside the drive rack is usually sufficient. For diagnostics or parameter download, the integrated RS-232 port supports data rates up to 115 kBaud, enabling quick transfers from a laptop without special adapters. Each digital output can source or sink up to 500 mA, enough for small solenoid valves or indicator lamps, while the card restricts the summed load on all outputs to 1000 mA to protect the onboard power stages and wiring traces.

The encoder input path uses 120 ohm termination, matching differential line drivers and minimizing signal reflections on long cables. An auxiliary encoder rail delivers 11.6 V so the feedback device receives regulated power independent of field supplies. During startup, the controller can tolerate an inrush pulse width of 100 ms, which allows capacitive loads on its supply lines without triggering undervoltage alarms. For inductive loads connected to the digital outputs, a single switching event may return up to 400 mJ of energy, and the output stages include clamping elements so that energy does not damage the board.
