Features & Benefits
- Cost-competitive, value-based alternative to the Logix 3800 digital positioner but with the same levels of quality, reliability and simplicity
- Facilitates asset heath monitoring when connected to the RedRaven platform to collect critical asset health data
- Plant operators are empowered to make data-driven decisions and implement preventive actions to minimize unplanned downtime
- Three robust housing options (explosion-proof, intrinsically safe and economical, plastic housing for general purposes) along with a rugged modular design provide protection from dirt and water ingress (IP-66), impact and vibration
- Trouble-free performance in demanding applications is ensured by the shielded, dual-element, non-contact, magneto-resistive position sensor and temperature-compensated, dual-poppet pneumatic relay
- An innovative quick-calibration feature greatly simplifies commissioning. One-button setup automatically configures the zero, span and gain of the positioner for most valves in less than 60 seconds.
- Broad application versatility with industry-leading communication technologies, including analog, HART, 4-20 mA or discrete I/O signals.
- Optional module to remotely locate the positioner from the control valve
- Intrinsically safe, non-incendive and explosion-proof design from -52°C to 85°C (-62°F to 185°F) ensures safe, reliable operation in hazardous conditions
- Up to 80% more air capacity with minimal air consumption is made possible by the double-poppet technology
