Product Description:

The CSH02.1B-ET-EC-EC-SB-EM-NN-FW is a controller card designed by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside IndraDrive modular servo systems, the unit coordinates drive axes, processes fieldbus data, and outputs analog and digital commands for motors, sensors, and connected safety functions. This role allows one control platform to manage motion behavior, signal exchange, and machine response within automated production equipment.

Its analog stage supplies a symmetrical voltage window of ±10 V, allowing proportional speed or torque reference signals, and two independent channels support separate command paths. All low-level electronics run from the control-side supply of DC 24 V, so the board remains active during short supply interruptions on the control circuit. Each digital output line can source up to 500 mA, while relay contacts carry 1000 mA for higher loads such as contactors. Network traffic is handled through a front-mounted RJ-45 8-Pin connector that follows the 100Base-TX standard, providing deterministic data exchange with external PLCs and HMIs. The integrated D-Sub 15-pin male socket routes resolver and sensor signals back to the control electronics for closed-loop operation.

Real-time communication travels up to 100 m over shielded copper, and the selectable Multi-Ethernet function allows the same hardware to operate with EtherCAT, EtherNet/IP, PROFINET IO, or sercos III. When a Safe Motion Bus ring is required, the embedded circuitry supports system-wide safety communication over the same cabling layout. That function draws only 7.1 W from optional plug-in modules, which helps limit added heat inside the cabinet. Two multi-encoder ports, an 11 Vpp resolver carrier, and two analog outputs give the controller the signal paths needed for synchronized multi-axis operation and coordinated feedback handling.
