PCB Terminals
A.
Power and
Communication:
J15 Input: Lower Terminal Output:
Upper Terminal (for communication use 2-24 AWG twisted and
shielded cable, Belden 9841 or equivalent)
B.
J8:
Pull down resistor
C.
J7:
1-2, end of line resistor 2-3, end of line RC filter resistor
D.
J12:
Pull up resistor
E.
4-20 mA Outputs:
J16 to J23 4-20 mA outputs may be set to be
Current sourcing or Loop-powered
Current Sourcing: S2 to S9 jumpers at 1-2, 3-4 and 5-6
Loop-Powered: S2 to S9 jumpers at 2-3, 4-5 and 6-7
When the output reads 3.33mA, the
IVA-420I
does not see the
corresponding transmitter.
WARNING
A dedicated power source must be used with the
IVA-420I
when
using current sourcing as input 4-20mA configuration.
