FT5200 FIELD MOUNT TRANSMITTER THERMOCOUPLE INPUT
- NEMA 4X Splashproof Enclosure
- Optional 3-1/2 Digit Display
- Available for All Thermocouple Types
- Automatic Cold-Junction Compensation
- Input/Output Isolated
- Urethane-Coated Circuit Boards
- AC or DC Power Options
The Model FT5200 Thermocouple Input Transmitter provides an isolated DC output proportional to a thermocouple input. Output and optional display are linear with millivolt input. Automatic cold junction compensation and a low-drift input amplifier maintain accuracy under varying ambient conditions.
A rugged NEMA 4X splashproof, corrosion-resistant housing protects the transmitter in outdoor and industrial environments. The circuit boards are urethane coated for protection against condensation and contaminants. FDT5000 Series transmitters include a 3-1/2 digit user-rangeable display to provide local process indication in degrees or other engineering units.
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 Numbers:
FT5200: Transmitter only. FDT5200: Transmitter with display.
Power:
Add suffix A (Model FT/FDT5200A) for AC power, D for DC power. Specify 115Vac, 230Vac, 12Vdc or 24Vdc.
Thermocouple Type:
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 degreed C or degrees F. (See Specifications below 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.
Display Range (optional):
If not otherwise specified, the display will be calibrated in degrees per your input range (1 degree resolution, 1999 maximum display). Other calibrations are possible: see "Display Capabilities" specification, below. Please note that the output and display do not compensate for thermocouple nonlinearity. Maximum accuracy will be at low end and full scale
Reverse-Acting Transmitter (decreasing output with increasing input):
Change last digit of the model number to 1 (for example, FT5201A).
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, FDT5202A).
Urethane Coating:
Specify Option U.
Conduit Connection:
Standard: A single 1/2 inch NPT conduit fitting (glass-fiber reinforced nylon) is provided at the bottom of the housing. Other options are possible, including no fitting at all. Contact factory
ELECTRICAL CONNECTIONS
Connections are made to 8 terminals within the enclosure:
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).BURNOUT INDICATION
Upscale burnout indication (standard) drives the output offscale high if the thermocouple breaks or burns out. Downscale (optional) drives it low. Upscale is provided unless otherwise specified on your order.
DETAILED SPECIFICATIONS
Input Thermocouple:
Available for types E, J, K, T, R, S, B or N. Contact factory for others.
Input Capabilities:
Any span 4mV or higher. (4mV equals 100 degrees C for type K thermocouple.) Offset ranges are allowed.
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).
Display Capabilities:
Low end and full scale readings may be anywhere between -1999 and +1999 counts. A fixed decimal point may be added in any position. Minimum span (full scale minus low end) is 10 counts. Reverse-acting display is possible (full scale reading downscale from low end). Display may be re-ranged by user. (Display is normally calibrated in degrees per the input range. If other settings are desired, please specify on your order.)
Endpoint Accuracy (factory calibration):
+/-0.1% of span or better (or, on narrow spans, +/-0.2OC or 20 microvolts, whichever is greater). The output and display are linear with millivolt input and do not compensate for thermocouple nonlinearity. Adjustability:
Zero and span each are adjustable approx. +/-15% of span.
Response Time:
Under 100 milliseconds.
Isolation:
3-way (Power/Input/Output) 1,500Vac rms (2,100V peak).
Guaranteed Operating Temperature:
-10 to +60oC (14 to 140oF).
Temperature Stability:
+/-(0.02% of span plus 1.3 microvolts) per oC, or better.
Power Requirements:
AC, 115 or 230Vrms, 50/60Hz, 2.5V-A. DC, 12 or 24V, 2.5W.
