DPM Squeezes Into Tight Designs

For cramped quarters, the Model 1PM digital panel meter (DPM) measures 1" x 1" x 0.5" while providing three 0.4" LED digits with over-range and negative indicators plus zero and span adjustment potentiometers. The DPM is powerless, meaning it derives power from the signals, i.e., 4-mA to 20-mA current loops. It can also be powered externally via 3 to 5 Vdc or 4 to 15 Vdc. Mounting is by way of four holes on the PCB or a plug-in header for PCB mounting. Decimal points, peak, and hold functions are included. OTEK CORP., Tucson, AZ. (877) 227-6835.
