Models JH4010 and JH4300 provide a DC output proportional to a DC
voltage or current input. Both are fixed-range devices, precisely
calibrated to your specified ranges at the factory. (For rangeable
devices see JH4380P Process Signal
Isolator and JH4380W Fully Rangeable
Transmitter.)
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.
Both models now include as standard a low-drift input amplifier
for millivolt-level inputs. This feature was formerly an extra-cost
option designated by Model Numbers JH4015 and JH4310. Available
options include input/output isolation (Model JH4300), 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: Input Signal plus (+).
Pin 6: Input Signal minus (-).
Pin 7: Output Signal plus (+).
Pin 8: Output Signal minus (-).
