Precision Digital ~ ProtEx PD6830X Modbus Scanner

HOLLISTON, Mass.—Precision Digital Corporation introduced its ProtEx® PD6830X Modbus Scanner designed for accurate display and quick access of information, locally or remotely, in hazardous areas or in harsh safe area applications.

The PD6830X is a rugged, explosion-proof, NEMA 4X/IP68 Modbus master, slave or snooper (sniffer). It can accept up to 16 individually programmed process variables (PVs) from multiple devices; four math channels allow for calculations on multiple PVs. The unique SafeTouch® through-glass buttons allow operation without removing the cover.

The pulse input accepts a wide range of flow transmitter signals, including mV input from a magnetic flowmeter, as well as high frequency signals. The PD6830X includes backlighting, two open collector outputs and an analog output as standard. The scanner has FM, ATEX, CSA, IECEx and CE approvals, enabling it to be installed almost anywhere. The PD6830X is housed in a durable, epoxy coated, cast aluminum enclosure. 

The PD6830X is designed for readability and ease of use, from large character and feet and inches displays to automatic rate conversions and data logging. In addition, it integrates easily into existing Modbus networks.

The PD6830X decimal display models feature an upper display that is 0.7 inches high and shows five digits of information; the feet and inches models feature a level display that reads up to 399 feet, 11 and 15/16 inches and contains a 20-segment tank level indicator. The lower display for both models is 0.4 inches high, with seven alphanumeric characters for Process Variables, Custom Units or Tags. The bright LCD display is easily read under various lighting conditions and from viewing angles of up to +/- 40 degrees (twice that of competitive models); it can also be rotated in 90-degree increments for increased readability.

Four sensors in the PD6830X operate as through-glass buttons for programming and operation without removing the cover in hazardous areas. These SafeTouch buttons include an energy saving mode to save power, extend battery life, and prevent unintended triggers.

The PD6830X provides flexible power options, including battery, DC with battery backup, DC only, output-loop, or output loop with battery backup.

Its element-resistant enclosure provides three threaded conduit holes and integrated pipe or wall mounting holes. Operating temperatures range from -40 to 75 degrees Celsius.

Last year, Precision Digital launched its ProVu® PD6262 and PD6363 Dual-Input Flow Rate/Totalizers.
