Product Description:

The CSH01.1C-NN-ENS-EN1-NNN-NN-S-NN-FW controller is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It serves as the command layer in drive-based automation, converting analog, digital, and encoder signals into coordinated motion control for connected drive functions. This arrangement allows the unit to process local feedback directly for positioning, speed regulation, and general axis control in automated equipment.

Power draw at idle is limited to 7.5 W, which helps reduce heat buildup inside the cabinet. The analog input stage presents 160 kΩ of resistance, so connected transducers experience only a light electrical load. For reference generation, the card supplies 5 V / 1 mA and uses a resolution of 19.5 mV/inc, giving 256 discrete steps across the available span. Discrete input terminals recognize 24 V / 3 mA levels, allowing direct connection to proximity switches and photo sensors. Because the unit is not equipped with a communication module or integrated safety functions, any networking beyond the RS-232 port and any SIL-related control must be provided by external devices.

At startup, the supply must accommodate an inrush of 4 A for approximately 100 ms. Each digital output can sink or source up to 500 mA, which allows the controller to operate small contactors or similar loads without an interposing relay in many cases. Diagnostic communication over the serial interface reaches 115 kBaud, supporting parameter access and status reporting. Encoder connections provide 12 V for primary feedback devices and either 8 V DC or 18.2 Vpp AC for secondary pickups. The onboard relay switches DC 24 V at 1 A and is rated for 1 × 10⁸ mechanical operations, which supports frequent status signaling.
