The Model JH5200 Thermocouple Input Transmitter provides an
isolated DC output proportional to a thermocouple input. Output is
linear with millivolt input. Automatic cold junction compensation
and a low-drift input amplifier maintain accuracy under varying
ambient conditions.
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.
Available options include AC and DC power choices, reverse-acting
transmitter (decreasing output with increasing input) and downscale
burnout indication (upscale is standard).
ORDERING INFORMATION
| Model
Number: |
Specify Model
JH5200A for AC power, JH5200D for DC power. |
| Thermocouple
Type: |
Specify any
standard thermocouple type (E, J, K, T, R, S, B or N), or
contact factory for others. |
| Input
Range: |
Specify range
required in deg. C or deg. F. (See Specifications for input
capabilities.) |
| Output
Range: |
Specify any DC voltage or current range allowed by the
"Output Capabilities" spec, below.
|
| Burnout
Indication: |
Upscale burnout
indication is standard. (Output goes high if thermocouple
input opens.)
If downscale indication is required, specify "Downscale
Burnout" on your order. |
| Power:
|
Specify 115Vac, 230Vac, 12Vdc or 24Vdc.
|
Reverse-Acting
Transmitter
(decreasing output with increasing input): |
Change last digit of the model number to 1 (for example,
JH5201A).
|
| 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, JH5202A).
|
| Urethane
Coating: |
Specify Option U.
|
INSTALLATION AND CONNECTIONS
JH5200 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: Thermocouple plus.
2: Thermocouple minus.
3: No connection
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).
