JH240 Datasheet, PDF (2/2 Pages) List of Unclassifed Manufacturers – 2-WIRE RTD TRANSMITTER

INSTALLATION
The 1-3/4 inch diameter JH240 is
designed to fit many standard
thermocouple-type connection
heads. It may also be mounted to any
surface using two #8 (or smaller)
screws. An optional DIN-rail
mounting clip (specify Model
JH240-DIN) allows the transmitter
to be snapped onto DIN rail. Width
is 1-3/4 inches.
CONNECTIONS
Connections are made to the
transmitter’s terminal strip.
Connections are:
“+” Terminal: Output/Power Loop.
Receives current from (+) DC supply.
“-” Terminal: Output/Power Loop.
Passes on current to the next series
loop device, or to the (-) supply.
Terminal A: RTD (opposite end from
Terminal C).
Terminal B: RTD compensation
(same end of RTD as Terminal C).
When connecting to 2-wire RTD,
jumper terminals B and C.
Terminal C: RTD.
RTD Type:
100 ohm platinum RTD. Factory
calibration is per DIN/IEC
standard unless otherwise
specified.
Output:
4/20mA, 2-wire (loop-powered)
output.
Accuracy:
+/-0.1% of span or 0.05 deg C
(0.09 deg F), whichever is
greater.
Adjustability:
Zero and span each are adjustable
approx. +/-15% of span.
Response Time:
Under 100 milliseconds.
Operating Temperature:
-40 to +80 deg. C (-40 to +176
deg. F).
Temperature Stability:
+/-(0.02% of span plus 0.005 deg
C) per deg. C, or better.
Power Requirements:
DC loop-powered. Requires at
least 12Vdc at the transmitter’s
output terminals. 36Vdc
maximum.
SPECIFICATIONS
Input Capabilities:
Minimum span 10 deg. C (18
deg. F). Maximum range includes
the RTD’s full temperature range.
Low end of range may be zero
degrees, elevated or suppressed.
