PD683 Loop Leader Loop-Powered Digital Panel Meter

New product
 
More info

The Loop Leader PD683 is a loop-powered, 1/8 DIN digital panel meter designed for demanding process control applications. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines; the meter gets all of the power it needs from the 4-20 mA loop. The PD683 loop-powered indicator is built in a shallow-depth case with an FM Type 4X front and features loop-powered backlighting and a wide -30 to 65°C operating temperature range. It doesn't matter if it's indoors or outdoors, in bright sunlight or a dimly lit plant, or in an area that is wet, dirty, hot, or cold, the Loop Leader can go just about anywhere.
