JH4051I Datasheet, PDF (2/2 Pages) List of Unclassifed Manufacturers – PLUG-N-PLAY STRAIN GAUGE TRANSMITTER

INSTALLATION
The JH4051I plugs into any standard
11-pin circular (“octal”) relay
socket. JH Technology offers two
sockets: DS011 for DIN-rail or sur-
face mounting and ST011 for Snap-
Track mounting (see the Accesso-
ries page).
CONNECTIONS
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: Input plus (bridge output).
Pin 5: Input minus (bridge output).
Pin 6: No connection.
Pin 7: Bridge excitation plus.
Pin 8: Bridge excitation minus.
Pin 9: Output plus.
Pin 10: Output minus.
Pin 11: No connection.
QUICK-CHECK LEDS
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.
SPECIFICATIONS
Input Capabilities:
4mV minimum span (0.4mV/V at
10V excitation). 10V maximum
span (1V/V at 10V excitation).
Offset ranges are allowed. (Input
Impedance: 200kohms.)
Excitation Voltage:
Adjustable from 4 to 12Vdc.
40mA maximum load. Factory
set to 10Vdc unless otherwise
specified. (Note: 120 ohm
bridges limited to 4.8V or less.
350 ohm bridges are ok to 12V.)
Voltage Output Capabilities:
1 volt minimum output span, -10
to +15V absolute limit. Offset
ranges are allowed. Maximum
output load, 10mA (1Kohm at
10V output).
Current Output Capabilities:
1mA minimum output span, 0 to
+25mA absolute limit. Positive
offsets are allowed, negative out-
puts are not. Output drive capa-
bility, 24V (1,200 ohms max. at
20mA output).
Accuracy:
+/-0.1% of span or 10 microvolts,
whichever is greater.
Adjustability:
Zero and span each are adjustable
approx. +/-15% of span.
Linearity:
+/-0.05% of span or better.
Response Time:
Under 100 milliseconds.
Isolation:
Power, 1,500Vac rms (2,100V
peak). Input/Output, 1,000Vac
rms (1,400V peak).
Operating Temperature:
-10 to +60^OC (14 to 140^OF).
Temperature Stability:
+/-(0.02% of span plus 1.3 micro-
volts) per ^OC, or better.
Power Requirements:
AC, 115 or 230Vrms, 50/60Hz,
2.5V-A. DC, 12 or 24V, 2.5W.
