Every unit is factory calibrated and inspected before dispatch; parameters on this page reflect shipped goods.
On-board ADC + digital output (RS485 / Modbus RTU / CAN) lets the WST1209 drop straight into smart weighing terminals without external instrumentation.
RS485 / Modbus
EtherNet/IP, Profinet and Modbus TCP variants of the WST1209 connect directly to plant PLCs for in-line filling, dosing and checkweighing sequences.
Profinet ready
OPC UA and MQTT variants push weight data from the WST1209 straight into MES / SCADA / cloud dashboards — no signal converter box required.
