Smart Range Model Notes
The AD-4212C-301 and AD-4212C-3100 are Smart Range models. These models provide a fine precision range and automatically switch to the standard range when the weighing value exceeds the precision range capacity.
The display returns to the precision range after performing RE-ZERO / tare. This makes the Smart Range models useful for applications with containers, fixtures, or tare loads where fine resolution is still needed during part of the weighing process.
Engineering and Integration Notes
The AD-4212C Series is intended for users who need precision weighing inside a machine or production system. It is different from a standard bench balance because the weighing unit can be installed into custom fixtures, compact automation cells, production enclosures, and process equipment.
For best performance, the module should be installed in a stable mechanical setup with proper vibration control, draft protection, static control, grounding, and suitable sample handling. For robotic or actuator-based loading, the system design should avoid shock loading, side loading, pan impact, over-travel, and contact with surrounding fixtures.
PLC, HMI, and Network Integration
The AD-4212C Series includes RS-232C communication as standard for connection to a PC, panel computer, PLC, or compatible data system. Optional accessories may support Ethernet, RS-485, USB conversion, BCD output, CC-Link, remote display, printing, or data logging depending on the control system and project requirements.
Contact us before ordering if your project requires PLC communication, HMI display, Ethernet conversion, Modbus, CC-Link, data logging, or custom automation integration.
