2-wire Loop Powered LED Indicator with Intrinsically safe approval
Model 6DV is a 4-digit, 8-mm-high (.3”), 7-segment red LED display, which is powered from a 2-wire current loop (4 to 20 mA), requiring no extra power source. The maximum voltage drop caused by inserting the 6DV into the loop is 4.0 V at 20 mA.
· The display range is programmable from -1999 to 9999 and the decimal point is also selectable (10–1, 10–2, 10–3 or without decimals).
· Programmable functions include input signal calibration, offset setting and linearization (SQRT, RT32 and RT52, and 21-point user’s table).
· In combination with Model 27HU, it provides the user with a low-cost, field-mounted HART Temperature Transmitter with LED Display.
· Compact housing: External dimensions of 70mm-dia. (2.76”) and 21mm-high (.83”) (See below Figure 1).

Intrinsically safe approvals are available from ATEX Directive (Europe) and FM (US, Canada). Differences between the 6DV and the 6DVI exist only in safety parameters (See Table 1).
A safety barrier with matching safety parameters to the 6DV or 6DVI must be installed for complete intrinsic safety. The safety barrier should meet the Ex-data of this unit and must be approved for hazardous location.Table 1

Model 6DV and 6DVI are approved to applicable standard of IEC60079 category: ia, and can be installed into hazardous areas Zone 0 (Europe) and Division 1 (US, Canada). They are covered for use in a potentially explosive atmosphere of the gas group (explosion group) including Hydrogen and Acetylene (See Table 2).
The 6DV and 6DVI Series also include an optional outdoor enclosure, model 6DV-B and 6DVI-B, which are able to be field-mounted.Table 2
