2 Certified / SIL 3 Capable
Safety Transmitters
The
One Series Safety Transmitter used in Safety Instrumented Systems
delivers the ultimate state-of-the-art diversity and redundancy
required in these systems. It provides both affordable and highly
reliable diversity along side either process transmitters or switches.
The One Series Safety Transmitter is the first
SIL 2 Certified / SIL 3 Capable transmitter designed solely for
safety system applications. Only the One Series Safety Transmitter
comes with an internal high-speed relay for the fastest emergency
shutdown. That simple design means fewer nuisance trips —
for greater safety, productivity, and throughput.
The
One Series Safety Transmitter was designed with features that simplify
installation, improve productivity, and eliminate nuisance trips.
“I Am Working” sensor diagnostics with redundant data
processing detect open, shorted, and plugged sensing elements.
The
transmitter’s analog output conforms to the NAMUR NE 43 standard
and provides process variable (PV) and detected-fault information.
Discrete outputs provide a fail-safe (open) emergency shutdown when
a fault is detected. Set point and deadband (reset point) are 100%
programmable.
The
instrument is password protected to prevent unwanted parameter changes;
eliminating the risk of tampering. In addition, LED backlighting enhances
viewing of process variables, parameters, and status in dimly lit
areas.
