Mighty Module Model SR2800
Potentiometer Position Input Two Wire Transmitter
The SR2800 is a low-cost, reliable, potentiometer input two-wire transmitter for field or panel mounting in various industrial housings and enclosures. It provides a DC output current (4/20 mA) proportional to the wiper position of a potentiometer.
The module utilizes a stable 2.5 VDC power supply to excite the potentiometer. Any value potentiometer from 1 kilohm to 50 kilohms may be used. The output ZERO and SPAN controls are accessible through the top of the case. Zero is adjustable ±20% and span ±15%. Terminations are made to screw terminal connectors on the top of the case.
Test points located on the SR2800 front panel allow verification of loop current value, with a milliameter, without breaking the loop current.
Remote tank level, valve or actuator position data acquisition.
The SR2800 can be mounted in a connection head (TSH-A6L), explosion-proof housing (XJAY), or on a flat surface using the two 4.5 mm diameter mounting holes provided. Standard 33 mm hole center spacing allows for mounting in most connection heads. The 5.08 mm center hole allows clearance for input wiring. An optional DIN-Rail mounting kit is available (DMP2000).
