Product Description:
The CSH01.1C-NN-EN2-NNN-MEM-NN-S-NN-FW belongs to the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. This control section is fitted to Rexroth drive units to process encoder feedback, condition I/O signals, and coordinate motion tasks within industrial automation cells. By combining dedicated encoder channels with analog and digital signal handling, the board supervises axis position and state information so the host drive can regulate torque, speed, or position as required.
The module’s core load on the power bus is 7.5 W, and it offers an analog output range of 5 V at 1 mA for reference or monitoring loops. Each digital input accepts a nominal 24 V / 3 mA, so standard PLC sources can be wired without external buffering, while every digital output can switch up to 500 mA to drive relays or indicator lamps. Encoder channel 1 supports EnDat 2.1, 1 Vpp, and 5 V TTL formats, while a second encoder channel is not equipped. The EN2 option consumes 6 W and supports cable runs up to 50 m when the sense conductors are unused or 75 m when sense lines are present, providing flexibility for machines with distributed feedback devices. Communication over RS-232 is available, although the controller slot is not equipped for fieldbus communication and the card does not provide integrated safety functions.
The MEM encoder emulation channel extends system compatibility and allows cabling up to 40 m. It can reproduce square-wave signals at a maximum of 1 MHz for high-resolution position loops while drawing only 2 W. A separate serial port supports data exchange at up to 115 kBaud for setup or diagnostic tasks. Because the control card lacks integrated safety functions and additional communication hardware, some system functions depend on the host drive and external safety relays.
