Dual Head Modbus Weighing Controller
SS-DH-WGHR-V4
The Dual Head Weighing Controller is one of its kind controllers that can perform weighing actions of two independent weighing stations. (i.e. two separate loadcells). The controller is primarily designed for double head weighing and filling systems. This controller can be synced with several of its kind of controllers to obtain multiple head weighing controls.
