overview
One Series Dual Electronic Pressure, Differential Pressure & TemperatureSwitches are designed for critical alarm and shutdown applications in harsh hazardous environments. A local indicator provides continuous notifi cation that the device is powered, healthy and whether the switch has tripped. The patented I Am Working (IAW? self diagnostics assure theoperator that the One Series will perform when called upon.Low level DC outputs (confi gurations D2A and D2B) may be used to trigger control circuits or as a discrete input to a process computer (DCS or PLC).
Models confi gured with 115 VAC and 230 VAC input/output enable the One Series to be powered by an AC source and switch AC or DC loads. The switch output modes may be confi gured by the user in the fi eld without rewiring.
An optional 4 to 20 mA analog output allows remote monitoring and trending of the process variable.
The self-contained, compact package allows for easy retrofi t of mechanical switches or transmitters.
Approved for Division 2 hazardous locations and harsh environmental conditions,this rugged design will stand up to your most demanding applications.
