Product Description:

The CSH01.1C-PL-ENS-ENS-EN2-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in modular drive racks, it processes motion commands in real time. It also converts field-level feedback and issues switching signals that synchronize servomotor axes with PLC sequences in industrial automation cells.

This module draws a base power of 7.5 W, which represents its internal logic demand before any I/O loading is added. Each digital input changes state once the line reaches 15 V, ensuring noise immunity on field wiring. Digital outputs can source up to 500 mA, allowing direct actuation of low-power contactors or indicator lamps. The card has sixteen channels in each direction in a 16 In / 16 Out parallel configuration, so discrete devices can be wired without extra expansion boards. Form-C relay contacts are rated at 24 VDC, 1 A; this electromechanical path is used when galvanic isolation from the drive backplane is required for external interlocks. An analog DAC furnishes 5 V at 1 mA for proportional valve or reference signal tasks, and RS-232 communication is supported over cables up to 15 m with a selectable pulse width ceiling of 100 ms for event timing.

During power-up the controller withstands an inrush current of 4 A, so supply sizing must accommodate this brief surge. Serial diagnostics stream at up to 115 kBaud, enabling parameter backups without slowing the machine cycle. The ENS encoder interface operates from an 11.6 V supply with 120 Ω input resistance and 500 mA current capability, suiting long differential runs. The second encoder channel (EN2) is powered from a 5.0 V rail, delivers 350 mA, and tolerates 35 Ω load resistance, making it suitable for TTL-level feedback. These limits help protect the controller from overstress in multi-axis drive installations.
