    MANUAL

Model JH4003I provides a DC output proportional to the position of a potentiometer or slidewire wiper. A fixed-range device, it is factory set, but you may specify 0/100% input travel or any expanded range covering a 10% or wider portion of the travel.

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.

Available options include input/output isolation (Model JH4003I), AC or DC power choices and reverse-action Option RT (decreasing output with increasing input).

ORDERING INFORMATION

Model Number

Select JH4003I -AC for AC power, or JH4003I-DC for DC power.

Input Potentiometer

It is not necessary to specify the potentiometer’s resistance. Just make sure it is no less than 100 ohms nor more than 100Kohms.

Input Range

Specify 0/100%, or any 10% or wider portion of the travel (for example, 60/70%).

Output Range

Specify any DC voltage or current range allowed by the "Output Capabilities" spec, below.

Power

Specify 115Vac, 230Vac, 12Vdc or 24Vdc.

Reverse-Acting Transmitter (decreasing output with increasing input)

Specify Option RT.

Loop-Powered Output

4/20mA "current sink" output stage for connection to devices whose inputs provide 24Vdc loop excitation. Specify Option LPO.

Urethane Coating:  

Specify Option U

INSTALLATION AND CONNECTIONS

These transmitters plug into any standard 8-pin circular ("octal") relay socket. JH Technology offers a socket suitable for DIN-rail or surface mounting (see the Accessories page). Pin connections are:

Pin 1: Power (AC or, if DC power option, DC plus).
Pin 2: No connection.
Pin 3: Power (AC or, if DC power option, DC minus).
Pin 4: Potentiometer ccw (0% travel).
Pin 5: Potentiometer wiper.
Pin 6: Potentiometer cw (100% travel).
Pin 7: Output plus.
Pin 8: Output minus.
