VT-HNC100-1-13/130

The VT-HNC100-1-13/130 from Bosch Rexroth Indramat embodies a pinnacle of precision in the VT-HNC Digital Axis Controllers series. This digital axis controller features 2 channels for simultaneous multi-axis control and an output current range of 4 mA to 20 mA nom.; ±23 mA max, accommodating a wide variety of proportional valves. Its robust design supports a maximum load resistance of 500 Ω and operates reliably across an operating temperature range of 0 °C to 50 °C. Weighing just 1.0 kg and measuring 71 × 155 × 204 mm, the unit integrates seamlessly into compact industrial cabinets.

With advanced electrical performance, the controller delivers 1.25 mV resolution and maintains low residual ripple of ±60 mV for stable actuator output. Non-linearity is constrained to 15 mV within the major working range (±9.5 V) and 35 mV at voltage extremes (±10 V), ensuring precision feedback. The input resistance of ~3 kΩ ±10% and programmable input logic levels (≤5 V low; ≥10 V high) allow flexible digital interfacing. Output stages conform to output logic levels (≤2 V low; ≤Vcc high) and support switching outputs across 8, 16 or 24 channels with a switching output max current of 50 mA. Communication and diagnostics are handled via an onboard RS232 serial interface at 9.6 kBaud, while optional high-speed bus interfaces including Profibus DP (≤12 MBaud), CANopen, and INTERBUS-S enable real-time networked control.

Operational versatility is enhanced by dedicated switching inputs (8, 16 or 24 channels) that integrate programmable logic for custom interlocks. An integrated transducer power supply of 5 VDC ±15%, 200 mA max directly supports closed-loop sensors, reducing cabinet wiring. Internal algorithms synchronize dual control loops for smooth multi-axis motion profiles, pivotal for robotics, CNC machining, and high-speed packaging systems. The controller maintains signal integrity under industrial noise conditions by leveraging the industry-standard 4-20 mA signaling protocol and robust electrical design.

Engineers will appreciate the ease of integration afforded by the compact 71 × 155 × 204 mm footprint and lightweight 1.0 kg form factor, which simplifies mounting in distributed control architectures. Native support for multiple fieldbus standards ensures compatibility with existing automation networks and simplifies expansion. The VT-HNC100-1-13/130 is ideal for industrial automation applications ranging from hydraulic and pneumatic valve control to precision motion systems in manufacturing and process industries.
