Dwyer 285ER-S5SS | Rotary Smart Positioner | HART, single acting, stainless steel
In a stainless steel enclosure, the Dwyer 285ER-S5SS Series 285 smart positioner provides single-acting control of rotary valves with HART communication. A 4-20 mA input drives the 0 to 90° stroke, and an LCD on the housing gives quick field checks.
- 285ER-S5SS auto calibration and analog feedback output
- 285ER-S5SS enclosure rated NEMA 4X (IP66)
- 285ER-S5SS rotary stroke 0 to 90°
- Air supply for the 285ER-S5SS: 20-101 psig (1.4-7.0 bar)
- 285ER-S5SS connections: 1/4" NPT air, 1/8" NPT gauge, 1/2" NPT, screw-terminal electrical
