JH5400 PDF DATA SHEET

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.
Power:	Specify 115Vac, 230Vac, 12Vdc or 24Vdc.
4-Wire RTD Input:	Specify Option 4W.
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 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:  Standard - no connection.
        (Option 4W - 4th wire of RTD (same end as terminal 3).
    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 Connection:	3-wire connection is standard. Specify Option 4W for 4-wire RTD.
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 (factory calibration):	+/-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 plus 0.002 deg C) per deg. C, or better.
Power Requirements:	AC, 115 or 230Vrms, 50/60Hz, 2.5V-A. DC, 12 or 24V, 2.5W.
