Precision Digital’s New Super Snooper Modbus® Scanners Feature 1/8 DIN or Explosion-Proof Enclosures

6 March 2014

Precision Digital, global leader in digital panel meters and control  instrumentation, today announced the Super  Snooper line of Modbus® scanners, including the ProVu® PD6080 Series of 1/8 DIN digital panel meters and the ProtEX®-MAX PD8-6080 Series of  explosion-proof scanners. The Super Snooper scanners can be set up as Modbus  RTU Masters, Slaves, or Snoopers, monitoring multiple Modbus devices for up to  16 process variables, including level, interface level, density, and  temperature. The meters also provide two independently programmed analog inputs  and an array of math functions for sum, difference, average, and ratio  calculations.
PD6080_PD6081 The ProVu PD6080 Series Super Snoopers are  NEMA 4X 1/8 DIN panel indicators with bright, easy to read digits. The PD6080 and PD6081 include dual analog inputs and an RS-485 serial  communications module, allowing integration of existing 4-20 mA transmitters  and Modbus devices on the same display. The PD6088 and PD6089 include on-board RS-485 serial communications and no analog inputs. The PD6081 and PD6089 have a unique feet and inches display, ideal for level  applications.

The ProtEX-MAX PD8-6080 Super Snooper scanners are housed in explosion-proof enclosures for use in hazardous areas. SafeTouch®, through-glass buttons provide  accessibility to the front buttons without removing the enclosure cover. The  entire product carries FM, CSA, ATEX, and IECEX approvals for use in hazardous  area applications.
PD8-6080  “Most Modbus  scanners are dated technology in the form of low-level software packages or DIN  rail devices with no display,” said Jeffrey Peters, President of Precision  Digital Corp. “The Super Snooper scanners integrate sophisticated packet  sniffing capabilities with industry standard packaging — 1/8 DIN housing that  meets NEMA 4X specifications or explosion-proof enclosures for hazardous areas.  With the ability to poll up to 16 process variables, a single Super Snooper can  replace an entire control panel’s worth of instruments.”

The Super Snooper scanners can be easily  integrated into an existing Modbus network. Remote displays can be added  without making changes to other Modbus devices. In Master mode, the Super Snoopers  are Modbus masters, polling slave devices for the process variables. In Snooper  mode, the devices display any process variable being polled on the bus. All the  process variables are clearly labeled with a custom tag and unit.

Each scanner  is provided with RS-485 Modbus RTU serial communications standard. Options  include up to four (4) relays, a 4-20 mA analog output, and dual 24 VDC power  supplies.  Expansion modules for the 1/8  DIN models add an additional four (4) relays, two (2) 4-20 mA outputs, and eight  (8) digital I/O.
