... Non-inverting inputs are overvoltage protected to ±250V, and CMRR is typically 86dB (dc to 60Hz). The DMS-40PC's epoxy-encapsulated package has an integral bezel and color fi lter. The moisture and vibration-proof package is extremely rugged and well suited for harsh environments and extended temperatures. Devices are fully specifi ed for 0 to +50° ...

... MOLEX connector, decimal point solder pads and attenuation resistor pads. A panel-mount retaining clip is supplied with each model. ground for the DMS-40PC internally connected to pin 3 (5V RETURN). Do not connect pin 10 to either pin 3 or your system ground as this will create a ground loop and possibly result in errone- ous readings ...

... Panel Meter Catalog contains an application note describing power sup- ply wiring and ground loop avoidance techniques. The DMS-40PC’s simplifi ed schematic, shown in Figure 1, can be very useful when debugging a malfunctioning circuit, especially if the user has some knowledge of operational amplifi ers (op amps). The meter’s high-impedance input consists amp powered from a ± ...

... IN LO Figure 4. 4.5-18V Power Supply Monitor that, before it is applied to the DMS-40PC’s inputs, has no galvanic connection (direct current path) to the meter or the meter’s power supply. The circuit shown in Figure 5 illustrates the necessary con- nections for measuring fl oating inputs. The 1.5V battery represents a true fl ...

... STROBE (~ 5μsec wide) is active only in the center of the cor- responding DIGIT DRIVE and BCD DATA outputs. POLARITY (pin F): This pin, which is also used inside the DMS-40PC to drive the negative-sign segment, indicates whether the last input signal conversion was positive (POLARITY set high) or negative (POLARITY set low) ...
