VT-HNC100-1-22A/W-24-P-0

Product Description:

Bosch Rexroth Indramat makes the VT-HNC100-1-22A/W-24-P-0. The controller can really make the most of system bandwidth and improve damping characteristics by isolating one hydraulic axis at a time and adjusting on the fly. That's particularly useful in industrial settings where each axis must deliver consistent performance when loads change quickly, or commands are altered rapidly. That kind of specialization pays off in those situations. The device runs on an 18- to 36-volt DC power supply, with 24-volt DC being the sweet spot. Operating within that range ensures stable transistor-level functioning and the proper reference voltage levels for analog-to-digital and digital-to-analog conversions. That 8-watt power draw covers the internal logic, processing and communication circuits. But depending on their properties, linked sensors and actuators may need extra current. If the voltage drifts outside that envelope—especially under voltage—that can lead to subsystem misunderstandings, logic failures or even thermal overloads due to poor voltage control.

You'll find the controller measures 106.5mm wide, 155mm tall and 204mm deep. It weighs about 1.2 kilograms. The 'W' in its part number indicates it's designed for wall-mount or cabinet installations due to its size and weight. Wall mounting can actually help with natural convection cooling. That small footprint also makes high-density control layouts in industrial enclosures possible. It shortens cable lengths and may reduce electromagnetic interference. When you're designing the mechanical integration, you also need to think about enclosure rigidity and vibrational damping—especially if hydraulic transients can generate structural shocks. The controller's form factor helps in dynamic situations by minimizing inertia when it's mounted on articulated equipment or movable substructures.

The unit's analog and digital interfaces are designed for high-resolution signal capture and output production. Those interfaces have a high 200 kΩ input impedance to keep the load on upstream transducers low. Differential analog inputs with a ±10 V range and five mV resolution let you read sensor signals precisely. That's especially useful for deciphering data from linear variable displacement transducers or pressure sensors. Voltage-mode outputs on the output side give you signals with a resolution of 1.25 mV and a range of -10 V to +10 V. Those are ideal for precise control of proportional valves. Current-mode outputs support the industry-standard 4-20 mA loop and extend to ±23 mA for more specialized control solutions. The TTL-compatible encoder input processes up to 250 kHz, giving you quick and precise position feedback for high-speed hydraulic applications. The digital I/O section lets you do intricate interlocking and sequential control logic with 24 programmable binary channels.
