Product Description:
The VT-HNC100-2-21/W-16-I-0 is a digital axis controller produced by Bosch Rexroth Indramat for the VT-HNC Digital Axis Controllers series. As part of the HNC100 digital numerical control family, it supervises hydraulic drive functions and executes motion commands issued by higher-level PLCs. This model belongs to component series 2 and attaches directly to a cabinet backplate through wall mounting. Its housing occupies 106.5 mm of horizontal space, allowing the module to coordinate cylinder positioning tasks without requiring excessive panel width. The controller is intended for applications that require synchronized management of hydraulic motion, pressure, and feedback signals within an automated machine.
Signal processing is supported by 4 analog current inputs that allow the controller to receive pressure or flow commands from remote interfaces. Two analog current outputs provide command signals for proportional valves, while four analog voltage inputs and four analog voltage outputs accommodate sensors and transducers that use voltage signaling. A bank of 16 digital input/output lines handles limit switches, alarm relays, and status flags at the required logic level. The incremental encoder channel accepts frequencies up to 250 kHz, supporting precise velocity evaluation on fast hydraulic axes. The electronics consume only 8 W during operation, reducing the thermal load inside the control cabinet. Internal reference generation supplies a stable ±10 V signal for external setpoint circuits and compatible analog devices.
The controller is supplied as a version for 2 hydraulic axes, allowing one module to manage the position and pressure loops of two actuators independently. System integration is supported by the InterBus S fieldbus, which transmits real-time process data to distributed control equipment without an additional gateway. Output drivers can switch loads up to 50 mA, permitting direct operation of optical couplers or small solenoids. An internal monitoring function disables affected channels if the permitted current is exceeded. The assembly weighs 1.2 kg, which limits the load placed on the cabinet backplate. An inductive position sensor is not included, so an external LVDT or magnetostrictive probe can be selected according to the cylinder and application requirements.
