Product Description:

The CSH01.1C-PB-ENS-NNN-MD2-NN-S-NN-FW control section belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It functions as the central processing and I/O node inside IndraDrive systems, directing servo axes and relaying status data to higher-level automation equipment. By integrating dedicated fieldbus, analog, digital, and encoder terminals on one compact board, it reduces cabinet wiring and allows motion sequences to be coordinated with minimal latency in assembly lines, packaging machines, and other industrial platforms.

Data exchange with the plant PLC is handled through PROFIBUS, enabling cyclic setpoint and diagnostic traffic without additional gateways. For continuous control signals, the board provides an analog channel that can deliver 5 V at up to 1 mA; this range is often used for reference potentiometers or trim voltages. Each transistorized digital output supports load currents up to 0.5 A, permitting direct actuation of contactors or indicator lamps. The integrated MD2 expansion adds 16 digital inputs together with the same number of digital outputs, so the axis controller can react to limit switches or preset mode commands locally. Safety technology is not implemented on this variant, which simplifies use in systems that already rely on external safety relays.

The encoder front end follows the Standard Encoder Evaluation format, and feedback cords terminate on a 15-pin D-Sub female connector that supplies 12 V power to incremental or absolute encoders. An additional SSI channel is available through a 6-pin RJ12 jack, with the sensor electronics fed by 24 V at up to 0.2 A so position information can be captured independently of the main encoder. For relay signaling, a dry contact rated at 1 A and 24 VDC is included, allowing isolation of alarms or drive-ready outputs from the logic domain. These hardware interfaces let the controller accommodate mixed feedback devices and peripheral loads without external breakout modules.
