MANUAL

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.

Standard transmitters include filtering to smooth measurements and minimize noise pickup. When fast response is needed, Option HS speeds the response time to approximately 1 millisecond. Other response speeds are available on special order.

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 JH5200 (standard) or JH5210 (linearized).                                                                               Add suffix, "A" (for example, JH5200A) for AC power, or "D" for DC power.
Thermocouple:  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.)
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.
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 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).
High Speed Response:  

Approximately 1 msec (See Specifications). Specify Option HS.
Urethane Coating:  Specify Option U.

Model JH5200/JH5210 snaps 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.
        (Note: On most thermocouples, red is 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).

DETAILED SPECIFICATIONS

Input Thermocouple:  Available for types E, J, K, T, R, S, B or N. Contact factory for others.
Input Capabilities:  Any span 4mV or higher. (4mV equals 100 deg. C for type K thermocouple.) Offset ranges are allowed.
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 outputs are not. Output drive capability, 24V (1,200 ohms max. at 20mA output).
Accuracy (end-point, factory calibration):  +/-0.1% of span. On low input spans, +/-0.25 deg. C or 20 microvolts, whichever is greater.
Adjustability:  Zero and span each are adjustable approx. +/-15% of span.
