PRODUCT 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 4-20 mA current input
signal and produces a proportional 21 to 103 kPa (3 to
15 PSIG) pneumatic output. The ETP-9500 offers more
flexibility as it is field selectable to accept either a 4-20 mA
or a 0 to 10 Vdc input signal to control the 21 to 103 kPa (3
to15 PSIG) 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 4-20 mA configuration and will accept a
wide range of AC or DC power supply voltages in the 0 to
10 Vdc mode.
