The IND560x (photo) is specifically designed for process control and manual weighing operations in Division 1 or Zone 1/21 hazardous areas. It contains analog or electromagnetic force restoration (EMFR) weighing technologies, and features a highly configurable operator interface with numerous programmable, on-screen prompts. The graphic display shows weighing transaction status clearly, helping to reduce errors. In filling and dosing applications, the instrument’s target update rate of 50 Hz allows process controls to be triggered in 20 ms. The scale instrument is coupled with the ACM500, a communications accessory module that provides bidirectional communication between the weighing terminal and a larger automation system, such as a programmable logic controller (PLC) or a distributed control system (DCS). The ACM500 and IND560x can be connected using either a copper-wire-carried current loop signal or a fiber optic connection. The ACM500 allows the IND560x to communicate with several devices using multiple protocols simultaneously. — Mettler Toledo International Inc., Solon, Ohio
