JH5200 THERMOCOUPLE INPUT TRANSMITTER
DIN-RAIL MOUNT, FIXED RANGE
|
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: | 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). |
| Urethane Coating: | Specify Option U. |
Model JH5200 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. |
