Product Description:

The VT-HNC100-3-3X-C-I-00-000 is a digital axis controller produced by Bosch Rexroth Indramat within the VT-HNC Digital Axis Controllers series. Intended for hydraulic motion applications, the module executes closed-loop numeric control for cylinders and pumps in automated presses, casting machines, or test rigs. Mounted on a standard DIN rail inside the control cabinet, it acts as the link between electrical measurement devices, proportional valves, and higher-level PLCs, converting setpoint data into precise valve commands for coordinated axis movement.

Each I/O slice supports 2 voltage and 2 current inputs, so standardized ±10 V or 4–20 mA transducers connect without external converters. The controller handles 3 hydraulic axes, letting one unit govern multiple motion sections simultaneously. For discrete logic, the board offers 11 digital I/O per slot and can drive up to 20 digital outputs, covering enable relays, limit switches, and diagnostic lamps. Physical integration is aided by the 35 mm DIN-rail profile that aligns with other automation modules. Position reporting accepts incremental and SSI feedback, giving the system the flexibility to use either pulse or serial encoders while retaining closed-loop accuracy.

The enclosure is rated IP20, so the unit resists finger contact but must be installed behind a panel where fluid or dust exposure is possible. Parameter upload is performed through the RS232 service interface because no TCP/IP port is included. Installation uses top-hat rail mounting, eliminating custom brackets and letting the controller share space with standard miniature breakers. Power reaches the electronics through a three-pin plug, and the device works without a bus connection or axis synchronization; instead, all loops run locally while position, pressure, force, and velocity control modes remain available.
