The ProVu PD6080 Super Snooper Modbus® scanner is a multi-purpose display and controller capable of scanning up to 16 Modbus process variables and accepts two analog process inputs. The scanner can be programmed as a Modbus RTU master, slave, or snooper. It is the ideal display for Modbus multivariable transmitters or for existing Modbus networks with transmitters in need of an easy-to-read and conveniently located remote display. As a master, the PD6080 can read up to 16 Modbus registers on up to 16 Modbus devices and automatically alternate each of these process variables (PVs) on the dual-line display along with a unit and tag for each. In snooper mode, the PD6080 can read any Modbus variable being polled by a master, which allows you to easily add a display into an existing Modbus network. Like all ProVu meters, the PD6080 includes UL / C-UL listing and CE marking, a NEMA 4X front, and AC or DC power options. Powerful math functions may be applied to the analog or Modbus inputs, such as addition, difference, average, and ratio.
