Analog Inputs
3.2.1
Analog Input Configuration Page
Information.
•
Up to 6 analog inputs – on standard boards (inputs A1 to A6).
•
Universal inputs – mV, mA, V, THC, RTD and resistance.
•
Internal cold junction compensation.
•
Linearization – of temperature sensors or any electrical input to allow use of non-linearizing transmitters.
•
Programmable fault levels and actions.
•
Digital filter – to reduce the effect of noise on inputs.
Example A – setting up:
•
a Type K thermocouple
•
measuring temperature in
°
C
•
displaying a range of 0 to 1000
°
C (e.g. Lineariser range 0 to 1000
°
C)
•
a fault detection level 10% above 1000
°
C (engineering/display range) and 10% below 0
°
C (engineering/display range)
•
in the event of a fault being detected and/or the fault detection level being exceeded the process variable is driven upscale.
Example B – setting up:
•
a current input of 4 to 20 mA
•
displaying a range of 0 to 200p.s.i.
•
a fault detection level 10% above 200p.s.i. (engineering/display range) and 10% below 0p.s.i. (engineering/display range)
•
in the event of a fault being detected and/or the fault detection level being exceeded the process variable is driven
downscale.
