PD6830 ProtEx-RTPApril 23, 2013 - Holliston, MA - Precision Digital Corporation, global leader in digital panel meters and control instrumentation, is pleased to announce the complete product approval of the PD8 ProtEX-MAX Series of Explosion-Proof Meters and Controllers. The ProtEX-MAX Series has been designed to offer the functionality and features of Precision Digital's most popular safe area products, integrating any ProVu®, Trident X2 , Snooper, or Vigilante® II model into a great looking, explosion-proof product with full agency approvals.

A special bezel, faceplate and electronics were designed exclusively for the ProtEX-MAX, giving the front panel a very finished appearance while housing the unit's additional electronics. Programming and operation of the meter can be done without opening the housing, using either the built-in SafeTouch® through-glass buttons or the RS-485 serial communication port with free Modbus® protocol. The PD8 ProtEX-MAX is housed in a rugged, cast aluminum NEMA 4X enclosure that provides three threaded conduit holes and integrated pipe or wall mounting holes. Operating temperatures range from -40 to 65 degrees C. The meters have FM, ATEX, CSA, IECEx, and CE approvals.

All models of the ProtEX-MAX are available with sunlight readable displays. The ProtEX-MAX is perfect for applications where the meter is either in direct sunlight or in applications where visibility may be impaired by smoke, fog, dust, or distance. There are eight (8) user-selectable intensity levels to choose from on most ProtEX-MAX models. The meters are easy to read from a distance, including models with a huge 1.2 inch display. All displays are visible under various lighting conditions and from wide viewing angles of up to +/- 40 degrees (twice that of competitive models).

The PD8 ProtEX-MAX Series is equipped with up to four sensors that operate as through-glass buttons so that it can be programmed and operated without removing the cover (and exposing the electronics) in hazardous areas. These buttons can be disabled for security via the connector switch located inside the base of the enclosure. To actuate a button, press one finger to the glass directly over the marked button area. When the cover is removed, the mechanical buttons located on the faceplate are used for programming.

Modbus and RS-485 Serial Communications are standard with all ProtEX-MAX models except PD8-154 and PD8-158. Refer to the PD8 manual addendum.

The PD8 ProtEX-MAX Series offers several power options, including 85-265 VAC or low voltage DC, enabling the units to install in virtually any system configuration. Multiple relays and 4-20 mA output options enhance the PD8's functionality. There are also one or two transmitter power supplies available.
