csRAAD Box™ Smart Sensor Network With the RAAD Box™, conventional strain gauge load cell systems can be transformed into advanced sensor networks. Instead of analyzing the combined signal from the load cells in the system, the RAAD Box embeds intelligence into each individual load cell, enabling you to analyze your system at the lowest level. Failures can be detected immediately, guard-ing you against costly downtime or product waste.
Power and Performance for Weighing Applications
IND110 Weight TransmitterThe IND110 provides an economi-cal way to connect an analog strain gauge scale or weigh mod-ules via 4-20mA to process control equipment.
IND131 Process TransmitterThis newest generation of process transmitters combines ultra-fast A/D conversion and digital filter-ing with a compact footprint and a wide choice of process interfaces. A crisp OLED display makes con-figuration very convenient. Also available in a junction box design for harsh and heavy washdown applications.
IND331 Process TerminalAll you get from an IND131, but additionally with a panel-mountable display. The design allows to panel mount the entire terminal as well as remote installation of the display, separate from the electronic. Also available in a desk/wall-mountable harsh housing.

IND131 and IND331 Packaged SolutionsEnhanced Terminals in Robust Enclosures
• IND131 and IND331 in enclosure with optional I/O• Each version can be configured with any of the terminals’
multiple interface and connectivity • Optional DC power supply available
Enclosure SpecificationsEnclosures are also available in painted mild steel (shown at left), stainless steel and fiberglass. The stainless steel enclo-sure housing the IND131 DIN and IND331 panel packaged solutions is rated IP66 (IP65, when used with IND331 panel mount terminal). Each type includes integrated mounting back-ets, and if required can be configured with a power supply.
Multiple Terminal Configurations AvailableWhen a single terminal is not enough, multi-terminal designs are available, with power supply, optional I/O, and additional features as required for the application.
Faster basic process controlThe IND131/IND331 combination serial and relay Discrete I/O option allows the terminal or terminals to be configured for efficient process control. User selection of latched or concidence targets in combination with user-configured limit values for up to three comparators create a time-saving and cost-effective process controller.
Customized InterfacesCustomize the packaged IND131 and IND331 for specific uses with convenient operators for I/O, such as annunciators and pushbuttons, making operator interactions even easier, more consistent and safer.

IND131xx and IND331xx Packaged Solutions
• Packaged IND131xx and IND331xx in Enclosures Approved for Division 2, Zone 2 and Zone 22
• Each version can be configured with any of the terminals' multiple interface and connectivity options
• Packages include an agency-approved 24 VDC power supply
Enclosure SpecificationsThe stainless steel enclosure housing the IND131xx DIN and IND331xx panel packaged solutions is FM-approved for use in safe areas, and in Division 2, Zone 2 hazardous areas. The enclosure is ATEX/IECEx certified for Zone 22 (dust) hazardous areas. Cable entry points can be either conduit hubs for use in the U.S., or ATEX-approved glands for European applications.• FM-certified enclosure, gas and dust • ATEX and IECEx certified for Zone 2/22 environments• Rated IP66, IP65 when used with panel-mount terminal• T5 temperature class rating
Multi-Terminal ConfigurationsWhen a single terminal is not enough, multi-terminal designs are available, with agency-approved power supply, optional ISB (Intrinsically Safe Barrier) and additional features as required for the application.
Load Cells in Hazardous AreasIn applications with load cells in-stalled in Division 1/Zone 1 or Zone 1/21 areas, an intrinsically safe ana-log load cell barrier (ISB) is required. IND131xx and IND331xx terminals packaged with a METTLER TOLEDO ISB05 provide an integrated solution for such applications.
Packaged Model Configurations
IND131xx and IND331xx packages are highly customizable. Figure 1 shows a system compris-ing an IND131xx with optional ISB05 barrier. Figure 2 shows an IND331xx panel-mount terminal (its front panel interface not shown). Packaged model configurations include an FM/CSA/ATEX approved power supply (24VDC at 1.3 A, 100-240 VAC, 50/60 Hz) and are available with any of the PLC inter-faces (EtherNet/IP, PROFIBUS DP, Modbus TCP, Allen-Bradley RIO, ControlNet, Device-Net), and Solid State DIO.
