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. ACCESSORIES
