Analog Output Module Terminology
The number of analog channels or points available in the module to connect to field
devices.
The output ranges in voltage and/or current modes the module will operate properly
within.
The number of binary weighted bits available on the digital side of the module for use
in converting the digital value to a analog signal.
The maximum current the module will drive using a voltage output signal.
The output impedance of the module using a voltage output signal.
The minimum and maximum resistance the module can drive using a current output
signal.
The amount of time required to complete the digital to analog conversion.
The linearity and calibrated accuracy of the digital representation over the entire
output range.
The effect of temperature on the accuracy of the module.
LED indicators on the module
Some modules require a separate 24VDC power source. The 24VDC output supply
at the local or expansion base can be used as long as you do not exceed the current
rating.
The amount of base current required by the module. Use this value in your power
budget calculations.
The minimum and maximum temperatures the module will operate.
The minimum and maximum humidity the module will operate.
Indicates whether the terminal type is a removable or non-removable connector or a
terminal.
The weight of the module.
The number of I/O points the CPU must dedicate to the module.
