The Type 3111 Compact Analog Circuit Card HVAC Pressure Regulator is an economical version of the Type 3100 series, expressly designed for use within these industry applications.

With overall product dimensions that are identical to the Type 3100, the 3111 has no remote feedback or logic output capabilities. Output pressure is limited to 150 psig maximum. Jumper selections include AC/DC power and several control signal ranges. Manual differential control signals are available upon request.

The Type 3111 is occupies a small footprint. It is designed to mount onto a panel, DIN rail, or directly to multi-station manifold. A manual override feature for output span adjustments is also available upon request.

This compact analog circuit card pressure regulator is ideal for Heating, Ventilating, and Air Conditioning (HVAC), OEM pressure regulation, space constrained applications, or any OEM application where high-performance air pressure monitoring is a required without sacrificing the high-end capabilities associated with full size I/P’s.
