Product Description:

The CSH01.1C-NN-ENS-EN2-NNN-L2-S-NN-FW is an I/O and motion control card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. In a multi-axis drive cabinet, this card sits in a modular slot of a Rexroth power section and coordinates analog, digital, and encoder signals between the drive and a higher-level PLC. By processing signal conditioning and closed-loop feedback on board, it allows industrial automation equipment to read sensor values, issue speed or torque commands, and actuate relays without separate interface modules.

The analog front end is designed for fast control loops. Its input channel has a bandwidth of 1.4 kHz, so step signals at that rate pass with minimal attenuation. A high input resistance of 160 kΩ prevents loading of delicate transducer outputs. On the output side, the card sources up to 1 mA and can swing to 5 V, a level suited for typical actuator or reference inputs. Digital command lines expect 24 VDC, and each consumes 3 mA, allowing direct connection to PNP switches. Together, these analog and digital limits set the timing and loading used during position, velocity, or process temperature routines.

Peripheral support continues with dual encoder supplies. The ENS rail delivers 12 V, while a separate 5 V feed powers TTL encoders on the EN2 channel, letting the controller mix incremental and absolute feedback types. All I/O rails draw from a shared limit of 1.1 A, so cabinet power budgeting must include that figure during simultaneous sensor excitation and relay pull-in. Field relays can switch currents up to 1 A at 24 VDC, giving enough capacity for pneumatic valve solenoids. A built-in RS-232 port provides serial diagnostics, and the plug set is rated for 20 insertion and removal cycles before contact wear may affect signal integrity.
