Interface For Display Of Process Instruments

M R K Engineers offers Thermalert GP monitor, which provides a compact easy-to-use interface and display for process instruments. The low cost 1/8 DIN digital panel meter comes standard with features which are optional on other panel meters in this price range. The GP monitor accepts input from any 0-5 V or 4-20 mA sensor. In addition, the monitor can be used with many non-contact infrared temperature sensors. Along with its large 4-digit LED display, the monitor provides user-defined 4-20 mA output and two adjustable set points/dead bands with alarm outputs capable of driving solid state relays. The GP monitor accepts 110 V-220 V AC power and provides a 24 V DC/50 mA excitation voltage capable of providing loop power to external sensors. For signal processing requirements the monitor provides peak hold, valley hold, and averaging and a user adjustable offset. Best of all there are no internal jumpers used for setup, as all monitor functions are configured via the front panel.
