Description

The ETP-9500 Series transducers convert an electrical input signal to a pneumatic output signal to position pneumatic damper and valve actuators in HVAC systems. The ETP-9520 accepts an industry standard 4-20mA current input signal and produces a proportional 3-15 psig pneumatic output. The ETP-9500 offers more flexibility as it is field selectable to accept either a 4-20mA or a 0-10 VDC input signal to control the 3-15 psig pneumatic output. The ETP-9520-PW accepts a field selectable pulse width signal to control the pneumatic output. The ETP-9520 is powered by the process loop signal and requires no power supply. The ETP-9500 is also loop powered in the 4-20mA configuration and will accept a wide range of AC or DC power supply voltages in the 0-10 VDC mode. The ETP-9520-PW requires a 24 VDC or 22 to 28 VAC power supply.
