EPC2LG ACI Pneumatic Transducer
$216.20
The ACI EPC2LG is an electronic-to-pneumatic transducer that converts analog input signals (0–5 VDC, 0–10 VDC, or 4–20 mA) into proportional pneumatic outputs (0–10 psi, 0–15 psi, or 0–20 psi). Featuring a dual-valve design and built-in pressure gauge, it delivers fast, stable, and accurate control for HVAC and building automation systems.
Overview
The ACI EPC2LG is a high-performance electronic-to-pneumatic transducer that converts analog input signals into proportional branch line pressure for HVAC control applications. Designed for precision airflow and pressure control, the EPC2LG features a dual valve configuration that ensures stable operation and fast response times.
This transducer is ideal for use in modern building automation systems requiring accurate and responsive control of pneumatic actuators, dampers, and valves. It comes with an integrated pressure gauge for easy monitoring and field adjustment.
