Model FT5600 and FT5610 AC Input Transmitters provide an isolated DC output proportional to an AC voltage or current input. Input/output isolation is standard to guard against shock hazards in power measurements and against ground loop errors. Inputs ranges may be zero based or may be expanded (for example, 50-150Vac).
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. FDT5600 Series transmitters include a 3-1/2 digit user-rangeable display to provide local process indication in engineering units.
Model FT5600 is average responding, calibrated to provide accurate RMS readings with sine wave inputs. Accuracy is better than 0.5% of span, but will be degraded with nonsinusoidal waveforms such as from SCR/Triac speed and power controllers or pulse-modulated motor drives. For accurate readings with nonsinusoidal waveforms use true-RMS responding Model FT5610.
Available options include AC and DC power choices and reverse-acting transmitter (decreasing output with increasing input).
ORDERING INFORMATION
Model Number:
Specify Model FT5600 for standard (average responding) or FT5610 for true-RMS response.
Optional Display:
Change FT to FDT (for example, FDT5600). Specify display reading at low end and at full scale, including decimal point if required. See "Display Capabilities" specification, below. Note that reverse-acting display is possible - full scale reading downscale from low end. Display may be re-ranged by user.
Power:
Add suffix A (for example, FT5600A) for AC power, D for DC power. Specify 115Vac, 230Vac, 12Vdc or 24Vdc.
Input Range:
Specify any AC voltage or current range allowed by the "Input Capabilities" spec, below.
Output Range:
Specify any DC voltage or current range allowed by the "Output Capabilities" spec, below.
Reverse-Acting Transmitter (decreasing output with increasing input):
Change last digit of the model number to 1 (for example, FT5601A).
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, FDT5602A).
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: AC signal input.
2: AC signal input.
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).TRUE-RMS OPTION
Model FT/FDT5600 uses average-responding AC/DC converter circuitry calibrated for RMS sine wave response. Pure AC power and other sine wave inputs will be highly accurate. Nonsinusoidal waveforms, however, such as from SCR/Triac power controllers or variable speed drives (pulsed), will produce appreciable errors.
True-rms response, Model FT/FDT5610, gives correct readings regardless of the waveform's shape.
