The JH6010I/6020I series provides an isolated DC output
proportional to an AC voltage or current input. Applications range
from power monitoring to millivolt-level AC signals from sensors.
Input/output isolation is standard to guard against shock hazards in
power measurements and against ground loop errors.
Accuracy is better than 0.5% of span. True-RMS models maintain
accuracy even with non-sinusoidal waveforms. (Standard models are
average-responding, calibrated for RMS sine wave response.)
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
off scale low while green-only indicates off scale high.
Available options include AC or DC power choices and
reverse-action Option RT (decreasing output with increasing input).

INSTALLATION AND CONNECTIONS
These transmitters plug into any standard 8-pin
circular ("octal") relay socket. JH Technology offers two
sockets: DS008 for DIN-rail or surface mounting and ST008 for
Snap-Track mounting.
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: AC signal input.
Pin 6: AC signal input.
Pin 7: Output plus.
Pin 8: Output minus.
APPLICATION NOTE – CURRENT TRANSFORMER INPUTS
When monitoring the output of a current transformer never use
current-input Model JH6020I. Unplugging the module will remove the
transformer’s secondary load, resulting in potentially damaging or
dangerous voltage spikes (up to several hundred volts).
Instead, use voltage-input Model JH6010I with an appropriate
precision external shunt resistor. For 0/5 amps we recommend
specifying a 0/250mVac input range with a 0.05 ohm, 0.1% 3 watt
external shunt. We offer Part No. R0.05/DS008, a precision shunt
resistor assembly pre-assembled to socket DS008. The socket snaps
onto DIN rail or may be surface mounted using screws.
