Product Description:

The CSH01.2C-NN-ENS-EN2-CCD-S1-S-NN-FW is a motion-control interface card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The card plugs into a Rexroth drive rack and manages axis regulation, fieldbus exchange, and low-level signal conditioning in industrial automation cells. By handling encoder feedback, analog references, and digital I/O, it coordinates drive behavior with higher-level PLC logic and supports deterministic positioning on assembly lines and packaging machines.

At its core, the module draws a base power of 8.5 W, while the initial energizing surge is limited to 4 A to help prevent breaker trips. Motion commands are distributed over the real-time SERCOS III cross-communication link, and a separate 100Base-TX engineering port supports parameter downloads and service access. The single analog output can source 1 mA for reference signals to external devices. Legacy serial diagnostics remain available through an RS-232 channel that operates up to 115 kBaud with cable runs not exceeding 15 m. A relay contact rated at DC 24 V / 1 A allows the controller to switch auxiliary loads such as brake solenoids or contactor coils without an external relay block.

The card also provides a buffered analog level of 5 V when a voltage-driven reference is required instead of the current loop. Secondary encoder port EN2 can deliver up to 350 mA at 5.0 V and tolerates a line load of 35 Ω, while a separate 12 V ENS feed supplies TTL encoders that need higher excitation. Pulse-train outputs are time-gated, and the maximum width is 100 ms, which simplifies duty-cycle monitoring in safety circuits. Digital socket S1 accepts field inputs on a logic rail of 24 V and can sink 0.5 A through its transistor stage, so sensors and limit switches can be wired directly without interposing modules.
