PROPLUS digital panel meters are full-featured, high-end, digital panel meters and the most powerful member of Yokogawa's 1/8 DIN meter family. The PROPLUS offers a complete range of meters for all price and performance applications. These meters are available with 2 or 4 relays with a 4-20 mA output. Field expansion modules are available that allow the PROPLUS to control up to eight relays, including digital inputs and outputs, or add advanced serial communications options! The dual-display provides more information, and makes it easy to program. High intensity display models can be viewed in bright sunlight, or where visibility may be impaired by smoke, fog, dust, or distance. The dual-line 6-digit display (999,999), advanced input signal conditioning selections, user programmable function keys, Modbus RTU serial communications, and optional expansion modules are only a few of the features found on PROPLUS digital panel meters.
