Yokogawa NFAI143-500/A4500 Analog Input Module

External Zero Adjustment

External zero is continuously adjustable with

0.01% incremental resolution of span. Re-range

can be done locally using the digital indicator with

rangesetting switch.

Integral Indicator (LCD display, optional) “◊”

5-digit numerical display, 6-digit unit display and bar

graph.

The indicator is configurable to display one or up to

four of the following variables periodically.;

Measured differential pressure, differential pressure

in %, scaled differential pressure, measured static

pressure. See also “Factory Setting.”

Local Parameter Setting

(Output signal code D, J and Q)

Parameter configuration by the external zero

adjustment screw and push button (Integral indicator

code E) offers easy and quick setup for parameters

of Loop test, Tag number, Unit, LRV, URV, Damping,

Output mode (linear/square root), Display out 1. and

Re-range by applying actual pressure (LRV/URV)

and Device Information.

Burst Pressure Limits

69 MPa (10.000 psi) for wetted parts material S,

except for Measurement span F.

47 MPa (6.800 psi) for wetted parts material other

than S or Measurement span F.

Self Diagnostics

CPU failure, hardware failure, configuration error,

and over-range error for differential pressure, static

pressure and capsule temperature.

User-configurable process high/low alarm for

differential pressure and static pressure is also

available.

Signal Characterizer (Output signal code D, J and Q)

User-configurable 10-segment signal characterizer

for 4 to 20 mA output.

Value through problem solving

By capturing changes in the condition of cooling water pumps and motors

with vibration sensors, cooling water pump parts can be replaced before

failure occurs. This prevents cooling water pump failure and damage to the

equipment to be cooled.
