Example:
A1M:0.600,1.000,1,0.500,0.100
0.600 AD value range 0.600
1.000 Start Value is “1.000” (4mA * 250 Ω =1)
1 Alarm Enabled
0.500 Threshold High
0.100 Threshold Low
Standard range of data captured in AD Channel 1 is 4~20mA.
AI1 value depends on user setting of “Range”, “Start Value” and the input current “c”.
Start Value = 4mA x 250
Ω = 1
AD Range = usually specified by the current type transducer
(c x 250 – Start Value)
AI1 = ------------------------------- x Range
(0.02 x 250 – Start Value)
AI1 reported value will be = Range x (0.012 x 250 – Start Value) / (5 – Start Value)
When current input is 12mA, AI1 = 0.6 x (0.012 x 250 – 1) / (5 – 1) = 0.3
When user requires:
High level alarm at 0.018mA
Low level alarm at 0.008mA
H = (0.018 x 250 – 1) x 0.6 / (0.02 x 250 – 1) = 0.525
L = (0.008 x 250 – 1) x 0.6 / (0.02 x 250 – 1) = 0.15
When AI1 value is over 0.525 or below 0.150, alarm will be triggered – SMS alert
message will be sent out to phone number 1 and relay 1 is turned on.
