JH5140/JH5150 Multiply/Divide Transmitters respond to the product
or ratio of 2 DC inputs and provide a proportional, isolated DC
output.
Standard calibration calculates the inputs and outputs on a
percent-of-span basis. For example, in a JH5140 multiplying
transmitter with 4/20mA inputs and a 0/10V output, when both inputs
are at 12mA (50%) the output will be 2.5V (25%). The equation is:
0.5 x 0.5 = 0.25.
Nonstandard calibrations are available, including dissimilar
input ranges and input-to-output offsets. We also can, as a special,
create the function, Output = (A x B)/C. Contact us with your
requirements.
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.
Voltage or current inputs and outputs may be chosen: the input
and output ranges need not be the same. Available options include AC
and DC power choices and reverse-acting transmitter (decreasing
output with increasing input).
ORDERING INFORMATION

Range: |
Specify any
DC voltage or current range allowed by the "Input
Capabilities" spec, below. |
| Output
Range: |
Specify any DC voltage or current range allowed by the
"Output Capabilities" spec, below.
|
| Power:
|
Specify 115Vac, 230Vac, 12Vdc or 24Vdc.
|
Reverse-Acting
Transmitter
(decreasing output with increasing input): |
Change the last digit of the model number to 1 (for
example, JH5141A).
|
| Loop-Powered
Output: |
4/20mA "current sink" output stage for
connection to devices whose inputs provide 24Vdc loop
excitation. Change the last digit of the model number to 2
(for example, JH5142A).

INSTALLATION AND CONNECTIONS
JH5000 Series transmitters snap onto 35mm DIN
rail. Connections are made to the front-panel terminals. The
terminal strip unplugs to facilitate calibrating or replacing the
transmitter.
Connections to the 8 terminals (top to bottom)
are:
1: Input A (Positive).
2: Input Common (Negative).
3: Input B (Positive).
4: No connection.
5: Output plus.
6: Output minus.
7: Power (AC or, if DC power option, DC
plus).
8: Power (AC or, if DC power option, DC
minus).
