The One Series Safety Transmitter was designed to simplify installation, improve productivity, and eliminate nuisance trips. The One Series Safety Transmitter is certified for use in SIL 2 functional safety applications (HFT=0), and is capable of SIL 3 applications when augmented by redundancy and voting logic.
These new combination transmitter/switches feature "I Am Working" sensor diagnostics with redundant data processing detect open, shorted, and plugged sensing elements. Their analog output conforms to the NAMUR NE 43 standard and provides process variable and detected-fault information. Discrete outputs provide a fail-safe (open) emergency shutdown when a fault is detected. Setpoint and deadband are 100% programmable. And its programmable high-capacity solid-state safety relay output enables the fastest emergency shutdowns.
