   Standard Display Colors:      Bi-color LED's are made using red and green LED's in the same package. Most indoor programmable LED displays today use either all red LED's or they use red and green LED's. To a lesser extent all amber is sometime selected. It is possible to create 256 or more shades of color from red to green using only red and green bi-color LED's. Blue LED's are the most expensive and have the highest brightness. Adding blue LED's to the red and green can give you over 1.7 million shades of color.
   Your choices are...
 
      
 
   Red
 
     Common Wavelength of 660 or 630 nm.
 
   Green
 
     Common wavelengths of 565 or 555 nm.

   Face Height:
 
      
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
Features




   Set Point Options?
 
     Ability to set control limits or set points for process parameters such as speed, temperature, pressure or humidity.  In a heating application, the unit sends an off control signal when the set point temperature is approached or exceeded and an on control signal when the temperature drops below the set point. Limit (on-off), linear (proportional, PID) or other non-linear control technologies can be used to generate the control signal.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Alarms?
 
     The meter has alarms to indicate when limits or set points are reached.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   On / Off Control?
 
     The meter has the ability to send an on-off output signal to activate or deactivate a process unit (oven, motor, fan, etc.)  utilizing relays, open collector transistors or other technologies.  On-off, bang-bang or limit control is one of the simplest techniques for process control.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Also Displays a Bar Graph?
 
     The panel meter also has an integral bar graph display in addition to the main digital display.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Adjustable Display?
 
     The meter can be adjusted to show different displays.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
Analog Inputs




   Analog Input Channels:
 
     Number of all analog input channels. This includes both general & specific types.
 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Analog Input Type:       
   Your choices are...
 
      
 
   AC Voltage
 
     VAC - Input is received as a measurable form of AC Voltage.
 
   AC Current
 
     mA AC - The input is designed to receive AC Current.
 
   AC Power
 
     Input is received as an adjustable range of AC current, voltage and/or frequency.
 
   DC Voltage
 
     VDC - Input is received as a measurable form of DC Voltage.
 
   DC Current
 
     mA DC - The input is designed to receive DC Current.
 
   DC Power
 
     Input is received as an adjustable range of DC current, voltage and/or frequency.
 
   Strain Gauge
 
     A strain gauge is a sensing device, attached along its entire length to a surface so that its resistance will change as the surface is deformed. Strain gages are typically used as elements in a Wheatstone bridge circuit, which is used to make the measurement.
 
   Resistance
 
     Piezoresistive sensors are based on semiconductor technology. The resistance changes because of alterations in the length and width (as with strain gauges) as well as a shift of electrical charges within the resistor.
 
   Temperature
 
     Thermocouple (TC), RTD or thermistor input accepted.
 
   Other
 
      
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
Outputs/Communications




   Serial Communications?
 
     A port, or interface, that can be used for serial communication, in which only one bit is transferred at a time.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Relay Outputs?
 
     One of the most common types of outputs available is the relay output. A relay can be used with both AC and DC loads.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Analog Outputs?
 
     Analog outputs are used in applications that require digitally controlled output voltages usually within the range of +/-10 V or less, and at current levels below 10 mA. The heart of an analog output channel is a digital-to-analog converter (DAC), which converts a digital code into a voltage level. The output of the DAC is then processed or conditioned to produce the required output signal characteristics.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
Environment




   Operating Temperature:
 
     This is the full required range of ambient operating temperature.
 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
