JH5400 RTD INPUT TRANSMITTER
DIN-RAIL MOUNT, FIXED RANGE
JH5400: 100 Ohm Platinum RTD, Linearized
Model numbers JH54x0 reserved for other RTD styles. Contact factory with your requirements.
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.
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 and reverse-acting transmitter (decreasing output with increasing input).
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.
Determined by model number.
Specify any input range allowed by the "Input Capabilities" spec, below.
Specify any DC voltage or current range allowed by the "Output Capabilities" spec, below.
Specify 115Vac, 230Vac, 12Vdc or 24Vdc.
Specify Option 4W.
Change last digit of the model number to 1 (for example, JH5401A).
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).
Approximately 1 msec (See Specifications). Specify Option HS.
Specify Option U.
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:
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).
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.)
3-wire connection is standard. Specify Option 4W for 4-wire RTD.
Minimum span 10 deg. C (18 deg. F) or 1 ohm, whichever is greater. Maximum range will cover any RTD's full temperature range.
1 volt minimum output span, -10 to +15V absolute limit. Offset ranges are allowed. Maximum output load, 10mA (1Kohm at 10V output).
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).
+/-0.1% of span or 0.02 ohms, whichever is greater.
Zero and span each are adjustable approx. +/-15% of span.
Platinum RTDs are linearized. Copper is inherently linear. Contact factory for information on others.
Standard: Under 100 milliseconds. Option HS: Approximately 95% complete in 1 msec. Frequency response 3dB down at approx. 600Hz.
3-way (Power/Input/Output) 1,500Vac rms (2,100V peak).
-10 to +60 deg. C (14 to 140 deg. F).
+/-(0.02% of span plus 0.002 deg C) per deg. C, or better.
AC, 115 or 230Vrms, 50/60Hz, 2.5V-A. DC, 12 or 24V, 2.5W.
