    DATA SHEET

The Model JH5050 4/20mA Current Isolator uses the same high-accuracy circuitry as our other 5000 Series Transmitters. The popularity of this range allows us to reduce costs by premanufacturing and stocking this version. For other ranges and a complete selection of options, please refer to the rest of our 5000 Series product line.

Red-green Quick-Check LEDs give a quick indication of the relative output. Red is brighter at the low end, green at high, while at mid-scale both are approximately equal. Red-only indicates offscale low while green-only indicates offscale high.

AC and DC power choices are available.

ORDERING INFORMATION

Model Number:  Specify Model JH5050A for AC power, JH5050D for DC power.
Input Range:  4/20mAdc only.
Output Range:  4/20mAdc only.
Power:  Specify 115Vac, 230Vac, 12Vdc or 24Vdc.

INSTALLATION AND CONNECTIONS

Model JH5050 snaps onto 35mm DIN rail. Connections are made to the front-panel terminals. The terminal strip unplugs to facilitate calibrating or replacing the transmitter.

Connections to the 8 terminals (top to bottom) are:
    1:  Input plus.
    2:  Input minus.
    3:  No connection.
    4:  No connection.
    5:  Output plus.
    6:  Output minus.
    7:  Power (AC or, if DC power option, DC plus).
    8:  Power (AC or, if DC power option, DC minus).
