Product Description:

The CSH01.2C-PB-EN1-EN2-CCD-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. The card serves as the command and communication core inside an automation cabinet, supervising drive functions, collecting feedback, and forwarding safety signals. By combining host fieldbus links, encoder supplies, and dedicated I/O on one circuit board, the module supports coordinated motion sequences across several axes while keeping installation compact. It also works as the central interface between the machine control layer and the connected drive hardware, so command flow and status reporting stay organized within the cabinet. Its moderate 7.0 W base power demand allows the board to share a common low-voltage rail without external cooling hardware.

Real-time drive synchronization is handled over SERCOS III, while higher-level controllers reach the module through PROFIBUS-DP. For setup and diagnostics, a 10/100 Base-T engineering port is available, and legacy tools can still connect through the RS232 serial interface. The board sources an analog reference of 5 V / 1 mA, enabling velocity or torque commands to be issued as a standard voltage signal. Digital status lines are accepted at 24 V / 3 mA, ensuring PLC inputs are detected without additional converters. This separation of communication, reference, and status functions allows the control section to exchange cyclic drive data while still supporting service access and conventional machine signals.

The module drives external actuators and indicators through a switching channel rated at 24 V / 0.5 A and an auxiliary relay that can carry 24 VDC at 1 A. High-resolution position data arrive on two independent encoder inputs: channel one accepts HSF or resolver feedback and provides an excitation of 8 V, while channel two is compatible with EnDat2.1 / 1 Vpp / 5 V TTL encoders that draw from a dedicated 5 V supply. Separate encoder paths let the control section work with different feedback types on the same machine without extra interface hardware. Integrated Safety Technology I/O supports category-rated stop functions, and a typical inrush of 4 A lets the board energize quickly without exceeding common circuit breaker curves. Output pulses on the fast channel can be stretched up to 100 ms when time-critical handshakes are required.
