Introduction:
The Apex 5100 I/P Module provides accurate
3-15 psi pneumatic signals for the Apex 5000
Positioner (shown). It receives 4-20 mA current
input and only requires six volts to operate.
The 5100 I/P has many advanced features
including: RFI protection, internal closed loop
control, integral filter (for start-up protection),
and automatic temperature compensation.
Applications:
The Apex 5100 I/P Module’s internal closed loop control system makes it insensitive to installed position. In
addition, this feature enables steady output under the most severe vibration. This transducer may only be used
with the A
pex Modular Positioning System (A.M.P.S.)
The Apex 5100 is designed to NEMA 4 specifications. It requires only 6 volts minimum DC power, enabling
series operation with other devices on 24 VDC current loops.
The I/P housing is constructed of durable die-cast aluminum and treated with a dichromate undercoat and
polyester powder top coat for protection against the toughest applications in all process industries including:
1. Chemical and Petro-Chemical
2. Power
3. Food and Beverage
4. Pharmaceutical
5. Municipal
6. Wastewater treatment

Features:
1. RFI immunity to both externally radiated RF and cable-conducted RF is provided by a conductive housing
and signal input filters.
2. Current loop connections are highly accessible and deplugable simplifying installation.
3. LED loop power indication simplifies troubleshooting.
4. Sensors automatically compensate for temperature fluctuations.
5. Internal regulator compensates for supply pressure changes.
6. Pressure feedback for precise output control, regardless of position, even under heavy vibration.
7. Internal zero and span calibration.
8. Integral filter provides initial startup protection against tubing scale or dirt.
Note: the integral filter is not designed to act as a permanent source of clean, dry air.

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.
