JH5400: 100 Ohm Platinum RTD, Linearized

  • Available for all RTD Types

  • Linearizes Platinum RTDs

  • 3-Wire Lead Compensation Standard
    (4-wire available)

  • DIN-Rail Mount, 1 Inch Wide

  • Unpluggable Terminal Strip

  • AC or DC Power Options

JH Technology DIN Rail Mount Signal Conditioners

JH5400 Series RTD Input Transmitters provide an isolated DC output proportional to temperature as measured by a resistance thermometer (RTD). Model JH5400 specifically designates 100 ohm platinum RTD input: additional model numbers are reserved for other RTD types.

Standard three-wire input circuitry compensates for lead wire resistance. A 4-wire input option is available. Platinum RTDs are linearized to provide true temperature indication. (Other types may or may not be: contact us to discuss your specific requirements.) A low-drift input amplifier helps assure accurate readings 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 and reverse-acting transmitter (decreasing output with increasing input).
 
ORDERING INFORMATION

Model Number:   Specify Model JH5400 for use with 100 ohm platinum RTDs. Other model numbers will be assigned for other RTD types. Add suffix A (for example, JH5400A) for AC power, D for DC power.
RTD Type: Determined by model number
Input Range: Specify any input range allowed by the "Input Capabilities" spec, below.
Output Range:  

Specify any DC voltage or current range allowed by the "Output Capabilities" spec, below.

4-Wire RTD Input: Specify Option 4W
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, JH5401A).

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, JH5402A).

Urethane Coating:  

Specify Option U.

INSTALLATION AND CONNECTIONS

JH5400 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: 
RTD.
    2: 
RTD compensation (same end of RTD as terminal 1).
    3: 
RTD (opposite end)
    4: 
No connection - Standard or 4th RTD wire w/option 4W.
    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

RTD Type:

Any RTD from 10 to 2,000 ohms. (Model JH5400 for 100 ohm platinum, other models JH54x0 for other types. Contact factory. Specify RTD type, resistance & slope.)
Input Capabilities:   Minimum span 10 deg. C (18 deg. F) or 1 ohm, whichever is greater. Maximum range will cover any RTD's full temperature range.

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:

+/-0.1% of span or 0.02 ohms, whichever is greater.

Adjustability: Zero and span each are adjustable approx. +/-15% of span.

Linearity:

Platinum RTDs are linearized. Copper is inherently linear. Contact factory for information on others.

Response Time:  

Under 100 milliseconds.

Isolation:  

3-way (Power/Input/Output) 1,500Vac rms (2,100V peak).

Guaranteed Operating Temperature:  

-10 to +60 deg. C (14 to 140 deg. F).

Temperature Stability:  

+/-(0.02% of span) per deg. C, or better.

Power Requirements:  

AC, 115 or 230Vrms, 50/60Hz, 2.5V-A. DC, 12 or 24V, 2.5W.
