SM815 Isolated Thermocouple Transmitter with Field Selectable Ranges

Fully Isolated 0.1% Accuracy Thermocouple Input Type J/K/T/E/R/S Dip Switch Calibration Thermo-Head Installation Field Rangeable Via Dip Switch (No Soldering) SM815 isolated two wire TC transmitter receives signals from thermocouples and provides a proportional 4 to 20 mA output signal which is completely  isolated from the input. Because the SM815 is a two wire device, a single pair of twisted copper wires are all that is required to provide power to the unit as well as to carry the output current. The SM815 is field calibratable, accepting inputs from type J, K, E, R, S & T thermocouples, with millivolt spans ranging from 4 to 64 millivolts. Thermocouple types and ranges are selected using a 6 position DIP switch and final calibration is accomplished by means of multiturn zero and span potentiometers. The zero pot provides an offset adjustment of ± 25% of the span. The SM815 is provided with upscale thermocouple break indication.  To Order the model below scroll to the top o
