Product Highlights
High-Precision Control: Features a system accuracy of better than 0.05%, ensuring ultimate stability in material dosing thanks to a 24 million-division resolution for the weighing signal.
Multi-Functional Application: This central unit is specifically designed for Loss-in-Weight feeders, weighfeeders, mass flow meters, and solids flow meters. It supports sequential batching control for up to 10 different materials.
Self-Optimizing Algorithm: Equipped with built-in batch control and adaptive optimization functions. The system automatically adjusts parameters based on weighing results, enabling highly precise automatic start-up zeroing and self-calibration.
Modular Expansion: Supports seamless integration into plant control systems via fieldbus modules, with options to expand additional analog I/O or weighing interface units.
Data Security: Features power-loss-protected data storage, ensuring all calibration data and configuration parameters remain safe and intact during power interruptions.
(FAQ)
Q1: What types of operating terminals are compatible with the VCU 20100?
A: It is typically used in conjunction with the VHM 20100 (embedded touchscreen), the VHM 20110 (hand-held terminal with cable), or a wireless hand-held terminal. It also supports remote maintenance via a web browser.
Q2: How do I perform software updates or specific application configurations?
A: The accompanying EasyServe PC software can be used for system commissioning, calibration, and loading application software via the RS232 or Ethernet interface.
Q3: Can it be used in harsh outdoor environments?
A: Yes, when installed in a VFG 20103 or 20104 field enclosure, it achieves an IP65 (NEMA4) protection rating, making it fully suitable for industrial environments on the plant floor.
