Two Solutions for Hazardous Locations Designed with the level of safety your location requires, the 320IS digital weight indicator meets hazardous environment requirements without hesitation. With Factory Mutual (FM) entity approval, it is the ideal solution for dangerous and highly explosive environments. Even in dimly-lit areas, the 320IS maintains brilliant visibility for user-friendly operation. The intrinsically-safe, auto-ranging power supply is designed to meet 320IS entity parameters and safely mount in hazardous areas. With this option, wiring is simplified to a single AC conduit line and seal from the safe areabarrier strips are no longer necessary. When required, an entity approved battery power supply is also available. For applications that require increased functionality, choose the 320IS Plus. It combines the same great features of the 320IS, but includes a full numeric keypad and keyboard tare. The 320IS Plus is also equipped with standard count mode. Expand the flexibility of the 320IS and the 320IS Plus with the optional safe area I/O Module, featuring two serial ports, two analog outputs, four digital inputs and four relay contact outputs, allowing communication with printers, computers and other peripherals. Both models are equipped with a duplex fiber optic port for electrically-isolated communication with the I/O Module. For IS entity approval, Rice Lake offers hundreds of FM-approved load cells that interface with the 320IS and 320IS Plus indicators in accordance with the official FM control drawings.
