Bulletin 837E Solid-State Switches

Allen-Bradley 837E temperature switches are solid-state condition sensing switches that are microprocessor based and designed with no moving parts, providing a longer service life and reducing downtime. Their rugged, corrosion-resistant 316 stainless steel construction offers an IP66 enclosure rating and allows these compact new condition sensors to withstand harsh industrial conditions, and the laser-etched label is more durable than the standard adhesive labels commonly found on similar products.

Switches are available in PNP switching output or analog output versions. The PNP switching output version features dual independently programmable PNP outputs, which can be set for either normally open or normally closed operation. The analog output version features a fully programmable 4 - 20mA analog output with a single independently programmable PNP output (NO or NC). Plus, the industry-leading 4-character, 14-segment digital display shows condition indication and the unit of measure selected as well as detailed menu options during programming.
