The ETP-9500 Series transmitters 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 21 – 103 kPa (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 21 – 103 kPa (3 – 15 psig) pneumatic output.
The ETP-9510/20 are 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.
