Model JH4380W provides an isolated DC output proportional to a DC voltage or current input. Input and output ranges are fully user-rangeable. Input/output isolation eliminates ground loops and guards against shock hazards when using high-voltage inputs. The input is filtered to minimize high-frequency noise and transients. A low-drift input amplifier provides superior performance with millivolt inputs.
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 or DC power choices are available.
For a fixed-range DC transmitter with additional options see Model JH4300. For a low-cost 4/20mA isolator see Model JH4300C.
Select JH4380W–AC for AC power or JH4380W–DC for DC power.
The JH4380W is normally shipped tested but uncalibrated. If you would like us to calibrate it to specific input and output range settings simply specify on your order. We’ll do it at no extra charge.
Specify 115Vac, 230Vac, 12Vdc or 24Vdc.
The JH4380W plugs 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: No connection.
Pin 5: Input plus.
Pin 6: Input minus.
Pin 7: Output plus.
Pin 8: Output minus.
Any zero-based voltage range from 0/10mV to 0/220V, or current range from 0/1mA to 0/100mA. Range also may be elevated 25% (such as 1/5V or 4/20mA) or suppressed 50% (center-zero such as –10/+10V or –1/+1mA).
Standard output ranges are: 0/5V, 1/5V, 0/10V, 2/10V, 0/1mA, 0.2/1mA, 0/20mA and 4/20mA. Negative outputs are not available.
+/-0.1% of span or 10 microvolts, whichever is greater.
Sufficient to achieve all specified input and output ranges.
+/-0.05% of span or better.
Under 100 milliseconds.
Power, 1,500Vac rms (2,100V peak). Input/Output, 1,000Vac rms (1,400V peak).

+/-(0.02% of span plus 1.3 microvolts) per deg. C, or better.
AC, 115 or 230Vrms, 50/60Hz, 2.5V-A. DC, 12 or 24V, 2.5W.
