The JH4410/4420 Series offers DC outputs representing the product
or quotient of two DC inputs. Input and output ranges need not be
the same; for example, the inputs could be 0/10Vdc while the output
could be 4/20mA. These are fixed-range devices, precisely calibrated
to your specified ranges at the factory.
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.
Input/output isolation is standard. (The inputs are not isolated
from each other.) Available options include, AC or DC power choices
and reverse-action Option RT (decreasing output with increasing
input).
Standard calibration calculates the inputs and output on a
percent-of-span basis. For example, for Output = AxB with a 4/20mA
input range and 0/10V output range, if both inputs are at 50% (12mA)
the output will be 25% (0.5 x 0.5 = 0.25), or 2.5 volts.
Nonstandard calibrations are available, including dissimilar
input ranges and input-to-output offsets. We also are able to
provide Output = (AxB)/C in one unit. Please contact us with your
special requirements.

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: "B" Input Signal plus
(+).
Pin 5: "A" Input Signal plus
(+)
Pin 6: Input Signal Common (-).
Pin 7: Output Signal plus (+).
Pin 8: Output Signal minus (-).
