2 / 6 page Performance/Functional Specifications Typical at TA = +25°C and supply voltage = +5V using the single-ended input circuit, unless otherwise noted. DMS-30PC - 1 - R S - C LED Color: AS = Standard Amber BS = Super Blue GS = Standard Green OS = Standard Orange QS = Standard Aqua RS = Standard Red YS = Standard Yellow RH = High-Intensity Red GL = Low-Power Green OL = Low-Power Orange RL = Low-Power Red VFS = Blue-Green 1. +1.23V REFERENCE OUTPUT (Pin 9): This pin is the output of the meter’s precision +1.23V internal reference, and it is referenced to ANALOG COMMON (pin 10) which sits at a potential of approximately +2V. This output should be buffered if used to drive external loads since sourcing more than 15μA from pin 9 can affect both the initial accuracy and temperature drift of the meter. 2. ANALOG COMMON (Pin 10): This pin is connected to an internal, low-noise, "relative" ground. It is used in certain differential and "floating" measurements as described in the Applications section of this data sheet and Ap Note 3 of the DATEL Panel Meter Catalog. Pin 10 should not be connected to pin 3 (5V RETURN) or to your system’s analog ground. 3. REFERENCE OUTPUT (Pin 8) and INPUT (Pin 7): Pin 8 is a preci- sion reference actively trimmed at the factory. In normal opera- tion, pin 8 must be tied to pin 7 to achieve all listed accuracy and drift specifications. Accessories: DMS-PS1-CM-C +5V/1.0A AC/DC power supply module DMS-30-CP Panel cutout punch DMS-BZL1-C DMS-30 bezel assembly DMS-BZL2-C DMS-30 bezel assembly with sealing gasket Add-On Application Boards: DMS-EB-C Multi-purpose (gain/offset, 4-20mA, etc.) DMS-EB-HTB High-accuracy temperature probe sensing for ±200mV models DMS-EB-DC/DC Provides isolated +5V power DMS-EB-RMS-C For true rms measurements of ac voltages DMS-EB-AC/DC-C For ac line-powered applications Input Range: 0 = ±200mV 1 = ±2V 2 = ±20V 3 = ±200V ±200V available on the following models only: -BS (Super Blue) -GS (Standard Green) -RS (Standard Red) -RL (Low-Power Red) -VFS (Blue-Green) Applies for transient or continuous overvoltages applied to (+) INPUT HI (pin 11) with (–) INPUT LO (pin 12) properly connected. Pin 12 is not overvoltage protected (see Figure 1). Voltages applied to pin 12 should not exceed the supply voltage. See Technical Notes. A panel-mount retaining clip is supplied with each model.
