Pressure or Temperature Safety Transmitter Switches

Manufacturer's part number :


Manufacturer United Electric

United Electric Controls

Description :

The One Series Safety Transmitter provides an explosion-proof type 4X/IP66, weather-tight enclosure suitable for harsh environments and hazardous (Class I, Division 1, Zone 1) locations and allowing the One Series Safety Transmitter to be mounted outside. Repeatability of 0.1% of maximum range rivals transmitters that cost much more than the One Series Safety Transmitter. Combined, these features provide an extremely accurate Safety Relay Output (SRO) set point that will not drift over time.

Model 2SLP is loop-powered and operates in a transmitter loop attached to an analog PLC or DCS input and provides a field-scalable 4-20 mA signal over a 2-wire connection. Model 2SLP contains an auxiliary solid-state relay switch rated for 12 - 250 VAC at 5 amperes.
