Product Description:

The VT-HNC100-1-2X-M-08-0-0 belongs to the VT-HNC Digital Axis Controllers series from Bosch Rexroth Indramat. It is a rack-mount digital NC unit intended to drive and monitor a single hydraulic axis in industrial machinery. By combining analog measurement, digital feedback, and onboard signal processing, the controller handles closed-loop positioning tasks that would otherwise require several discrete cards. This arrangement lets one module process feedback, command values, and output signals for hydraulic motion control inside a compact rack. Its 155 mm height allows it to fit beside other control modules in standardized 19-inch cabinets without exceeding typical vertical space.

The module provides four current input channels, four voltage input channels, two current outputs, and four voltage outputs, while its discrete section offers 8 input/output lines for limit switches or status bits. Incremental encoder signals are accepted up to 250 kHz, enabling high-resolution position feedback on fast hydraulic cylinders. That mix of analog and digital interfaces allows the controller to read process signals and send command values from the same unit. For setup or parameter backups, the front panel includes an RS-232 (9.6 kbaud) port, and analog command values are referenced to ±10 V ±25 mV for compatibility with most motion controllers. Internal electronics draw only 8 W, which helps keep cabinet heat low and supports passive airflow in many installations.

This controller is built for 1 hydraulic axis and is supplied without a bus connection, so fieldbus traffic must be handled through external gateways when needed. Mechanical accommodation is simplified by a front width of 71 mm and a weight of 1.0 kg, which keeps the unit compact and easy to handle in a rack. The 204 mm depth matches standard rack guides, and the unit uses the 2-series hardware platform. No inductive position sensor is built in, which allows the feedback device to be matched to the required stroke length, cylinder arrangement, or sealing layout.
