Product Specification

The Apex 5100 I/P Module converts 4-20 mA current signals into 3-15 psi pneumatic signals needed by the

Apex 5000 Positioner. A controller card compares the input signal with an electrical pressure feedback signal

and outputs voltage, which is applied to a coil.

The coil voltage varies a magnetic field strength which influences a metallic diaphragm. This diaphragm

throttles air flow out of the positioner input chamber (supplied by the internal regulator). As voltage and field

strength increase, the diaphragm moves closer to the coil nozzle, reducing air flow and increasing positioner

input chamber pressure.

The controller circuit board features temperature compensation and input signal filtration to provide accurate

3-15 psi output signals.
