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.
| 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. |
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).
