Mighty Modules Model SR2400
Thermocouple Input Field Rangeable Two Wire Transmitter
The SR2400 is a low-cost, reliable, thermocouple 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 a thermocouple input.
The SR2400 includes filtering and conditioning to reduce susceptibility to transients and noisy operations.
Ranging is accomplished via a plug-in range card which characterizes the input to the desired thermocouple type and sets the temperature range and burnout protection (upscale or downscale). Cold junction compensation is provided by a solid state temperature sensor embedded in the thermocouple input terminal strip. 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 transmitter's front panel allow verification of loop current value, using a milliammeter, without breaking the loop current.
Remote temperature data acquisition.
The SR2400 can be mounted in a thermocouple 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 or for a 3/16 inch diameter temperature probe. An optional DIN-Rail mounting kit is available (DMP2000).
