Product Description:

The CSH01.1C-NN-ENS-NNN-MD1-NN-S-NN-FW is a modular controller card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The board mounts on an IndraDrive power section and handles axis coordination, PLC logic, and safety monitoring in packaging, printing, and material-handling equipment. It exchanges real-time data with servo inverters, field sensors, and higher-level control systems, so it serves as the central command element in complex multi-axis machines. This arrangement keeps motion control, logic processing, and safety-related functions on the same drive platform.

During normal operation, the controller draws a base load of 7.5 W, and the ENS safety module adds 6 W, which helps determine the required power supply and cooling capacity. When the unit is energized, an inrush current of 4 A occurs for less than 10 ms, so the supply path must tolerate that brief transient. Eight transistor outputs can each source 500 mA for relays, indicator lamps, and similar low-power loads, and the integrated encoder supply provides a stabilized 11.6 V at up to 500 mA for feedback devices. A D-Sub 15 female connector carries the encoder lines, and an RJ-45 8-pin port provides the 100Base-TX engineering interface for high-speed communication without removing the board.

The engineering connection can operate over distances of up to 100 m when a shielded cable is used, which allows access from outside the electrical enclosure during setup or diagnostics. The MD1 expansion includes 12 optically isolated digital inputs and eight outputs, and its timing logic recognizes pulse commands with widths down to 100 ms for controlled sequencing of pneumatic valves or gate interlocks. For legacy equipment, the board also provides an RS-232 interface that accepts cable runs of 15 m and supports transfer rates up to 115 kBaud, so diagnostic communication can continue when the Ethernet network is unavailable. This combination of Ethernet, serial, and local I/O support allows the board to communicate with newer networked devices and older auxiliary equipment.
