The following list summarizes the various components in the overall PIM connectivity block

diagram.

l The field device connects to the IOTA screw terminals labeled SIG IN(x) and COMMON(x) where

“x” denotes the channel numbers 1 through 8.

l The field sensor pulse output is conditioned by the input protection circuitry and filtered to

reduce unwanted high-frequency noise. The filtered output is fed to the high-speed

differential comparator which has a user-selectable threshold control. From Control Builder,

you can select an appropriate low or high voltage threshold based on the sensor type and the

value of the signal amplitude (Vs).

l Comparator hysteresis is also provided to further reduce false triggering especially for slow

rise/fall time signals.

l Each of the eight PIM input channels are electrically isolated from one another and from

system ground (cabinet ground).

l A comparator monitors the isolated +24 V channel power supply with respect to COMMON(x)

and can detect a problem in the field wiring. If the output of the isolated supply falls below 22V

or rises above 26V, a failure is indicated. Failures can be any of the following;

o A short in the field wiring.

o EXT BIAS(x) pin is shorted to COMMON(x).

o Excessive current is being pulled from EXT BIAS(x) pin.

o Power supply fails for some other reason.

If a failure occurs, the soft failure is reported in Control Builder and Station
