These transducers are used in HVAC systems to
provide an accurate signal for positioning damper
and valve actuators based on branch line pressure.
They convert an analog voltage (E) or current (I)
signal into a linear pneumatic (P) output signal for
accurate positioning of damper and valve actuators
used in HVAC systems.
They are not position sensitive devices and can be
mounted vertically or horizontally. They provide
a direct output feedback signal for branch line
They can be powered by either 24 VAC or 24 VDC,
and have three selectable input ranges. The analog
signal may be either 1 to 5 VDC, 2 to 10 VDC, or 4 to
20 mA, which provides a 3 to 15 psi linear pneumatic
output signal. A 1 to 5 VDC output feedback signal,
proportional and linear to the 3 to 15 psi output
signal, is provided. A gauge tap is also provided
for pressure output indication. Standard 3.25" Snap
Track is supplied for mounting.
The XEC-3004 (only) also has a manual override that
