JH4051I
PLUG-N-PLAY STRAIN GAUGE TRANSMITTER
FEATURES
• Input Spans as low as 0.4mV/V (at 10V excitation)
• Offset and Nonstandard Ranges Available
• Excitation Adjustable from 4 to 12V
• Input/Output Isolation is Standard
• Quick-Check Red/Green Output LEDs
• Industry Standard Pinouts (11-Pin Socket)
• AC or DC Power Options
DESCRIPTION
Model JH4051I supplies DC excitation to a strain gauge or other resistance bridge, amplifies the bridge output and
provides a proportional DC voltage or current. A fixed-range device, it is precisely calibrated to your specified range
at the factory.
Fully adjustable excitation permits use with bridge resistances as low as 120 ohms while staying within the transmitter’s
40mA excitation supply capability. A low-drift input amplifier maintains accuracy under varying ambient condi-
tions.
Input/output isolation is standard. Available options include AC or DC power choices and reverse-action Option RT
(decreasing output with increasing input). Bridge applications other than strain gauges are possible: contact the
factory with your requirements.
HOW TO ORDER
Model Number: JH4051I
Power:
Add suffix –AC (JH4051I-AC)
for AC power or –DC for DC
power. Specify 115Vac, 230Vac,
12Vdc or 24Vdc.
Input Range:
Specify range required in milli-
volts (mV), volts (V) or millivolts
per volt (mV/V). For example,
with 10V bridge excitation a
range of 0/20mV is the same as
0/2 mV/V. See Specifications (on
www.DataSheet4U.com
back) for input capabilities. Off-
set input ranges are allowed.
Bridge Excitation:
User-adjustable. Normally fac-
tory-set to 10V. For other settings
specify any voltage between 4
and 12Vdc. (Note: 40mA maxi-
mum load. For 120ohm bridges,
specify 4.8V or less.)
Output Range:
Specify any DC voltage or cur-
rent range allowed by the “Out-
put Capabilities” spec (see back).
Reverse-Acting Transmitter:
Decreasing output with increas-
ing input. Specify Option RT.
Loop-Powered Output:
4/20mA “current sink” output
stage for connection to devices
whose inputs provide 24Vdc loop
excitation. Specify Option LPO.
Urethane Coating:
Specify Option U.
