WT331 Industrial Weighing Terminal

Stable and reliable performance: all-metal housing, excellent anti-interference capability; perfect self-diagnostic function; green, low-power design; multi-stage anti-vibration filtering; multi-stage power supply and signal isolation processing
Rich communication interface: optional industrial Ethernet ProfiNet, EtherNet/IP, fieldbus Profibus DP, CC-Link, Modbus RTU, 4~20mA/0~10V analog output, easily embedded into PLC or DCS system. Standard support for RS232, 485, support for a variety of serial output formats
Easy and fast installation : Perfectly compatible with the old 331, easy to install and replace. "cal-free calibration" function allows calibration without weights
Wide range of applications: the WT331P series can be configured in different versions to support weighing display, bus communication, industrial Ethernet, constant value control, checkweighing and sorting, material alarm, etc.
