Multi-purpose safe area modbus scanners.

The Vantageview PD6730X Modbus Scanner, from Precision Digital Corporation, is a rugged, NEMA 4X/IP65 Modbus master, slave, or snooper (sniffer). The multi-purpose PD6730X is designed for accurate display of and quick access to information, locally or remotely, in wet or dirty environments. 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-window 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 instrument includes backlighting, two open collector outputs, and an analog output as standard. The scanner has been manufactured to Precision Digital’s exacting standards and is housed in a durable, injection-molded thermal plastic enclosure.
"The versatile Vantageview PD6730X is loaded with features that plant operators can appreciate," said Jeffrey Peters, President, Precision Digital Corporation. "It is simple to program using our free ScanView EX software, displays critical information about the process, and can be seen from wide angles and a distance. The PD6730X is designed for readability and ease of use, from large character and Feet & Inches displays to automatic rate conversions and data logging. Plus, it integrates easily into existing Modbus networks."

The Decimal Display models feature an upper display that is 0.7 inches high and shows five digits of information; the Feet & 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 varying 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 unit operate as through-window buttons for programming and operation without removing the cover in wet or dirty areas. These SafeTouch buttons include an energy saving mode to save power, extend battery life, and prevent unintended triggers.

The PD6730X 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 C.
