JH Tech JH240
The JH240 is a loop-powered device. The JH240 does not provide input/output isolation. Its small 1-3/4 inch diameter allows the transmitter to fit most standard thermocouple-type connection heads.| Part No. | JH240 |

DESCRIPTION
The Model JH240 2-wire transmitter provides a 4/20mA current loop output proportional to temperature as measured by a 100 ohm platinum RTD (resistance thermometer). A fixed-range device, it is precisely calibrated to your specified input range at the factory. (For a rangeable 2-wire RTD transmitter see Model JH245.) RTD linearization is provided. Three-wire input circuitry eliminates errors due to lead wire resistance. Conformal coating protects the circuitry against condensation and corrosion in industrial atmospheres. The JH240 is a loop-powered device. Connected in series between a 24Vdc supply and readout instruments, it receives its power from the 4/20mA output loop. A built-in LED indicates loop current: dim at 4mA, bright at 20. It also may be surface mounted.
