Model JH4380P isolates and converts standard process signals. It
is useful for eliminating ground loops and noise problems as well as
for converting between 4/20mA loop currents and standard
instrumentation voltages. Clearly marked slide switches, accessible
through the top of the module, eliminate the need for instructions
and charts.
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.
Isolation to 1,000 Vac RMS is provided, with linearity better
than 0.05%. Low drift circuitry provides high accuracy and
stability. The input is filtered to minimize high-frequency noise
and transients. AC and DC power choices are available.
For a fully-rangeable DC transmitter see Model JH4380W.
For a fixed-range transmitter with additional options see Model JH4300.
For a low-cost 4/20mA isolator see Model JH4300C.

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: Input Signal plus (+).
Pin 6: Input Signal minus (-).
Pin 7: Output Signal plus (+).
Pin 8: Output Signal minus (-).
