Control Valves Positioners & Switches 194 EP5 Electro Pneumatic Positioner ISP5 Intrinsically Safe E/P Positioner Description The EP5 is a 2-wire Positioner requiring a 4-20 mA input signal, and is for use with linear pneumatic actuators. The positioner compares the electrical signal from a controller with the valve position feedback, and varies a pneumatic output signal to the actuator accordingly. The valve position is therefore guaranteed for any controller output signal and the effects of varying differential pressure, stem friction and diaphragm hysterisis are overcome. A mounting kit is supplied with each positioner for mounting to either columns or yoke in accordance with IEC60534-6-1 standards. The positioners can be used with the following actuators: PN1000/2000, 3000/4000, 9000. Technical Data Input signal range 4-20 mA Output signal range 0 to 100% supply air pressure Supply air pressure 20 to 90 psig (1.4 to 6 barg) Stroke range .4" to 4" (10 to 100 mm) Sensitivity Less than 0.2% span Linearity 1.0% span Hysterisis Less than 0.5% Input impedence 200 ohms I Max 50 mA Temperature Limitations 0 to 175° F (-15 to +65°C) Enclosure rating IP54 (approximate equivalent of Nema 3 enclosure) ISP4 Intrinsically safe to EEx.ia llc T6.T5.T4 (CESI) (approximate equivalent of FM Class I and II, Div. 1, Groups A, B, C, D) Steady State Air consumption 13.06 ft 3 /h at 90 psi (0.7 m 3 /h at 6 bar) Pneumatic connections 1/4" NPT Electrical connections PG 13.5 How To Specify 1- EP5 Electro pneumatic positioner.
