FDT5000 Series Field Mount Transmitters provide an isolated DC output proportional to a DC voltage or current input. They are useful for amplifying, reducing, scaling or offsetting signals, for eliminating ground loops and noise problems and for converting currents to voltages or vice-versa. The model numbers listed below reflect a variety of input choices but all share the same basic circuitry, features and specifications.

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 engineering units.

Model FDT5070 incorporates a low-drift amplifier for millivolt-level inputs. All models use stable, proven circuitry for accurate measurements under varying ambient conditions. Available options include AC and DC power choices and reverse-acting transmitter (decreasing output with increasing input).

For field mount transmitters without a display, select any plug-in transmitter module plus our ENCL-1 NEMA-4X enclosure.(see Accessories page)

ORDERING INFORMATION

Model Number:  

Select from the above list according to your input range. Add suffix A (for example, FDT5000A) for AC power, D for DC power.
Display: 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.
Input Range: Specify any DC 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.
Power: Specify 115Vac, 230Vac, 12Vdc or 24Vdc.
Reverse-Acting Transmitter(decreasing output with increasing input): Change last digit of the model number to 1 (for example, FDT5001A).
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, FDT5002A).
Conduit Opening: Standard: None. The enclosure has knockouts. Option NPT: Single 1/2 inch NPT fitting (glass-fiber reinforced nylon) at the bottom of the housing.

ELECTRICAL CONNECTIONS

Connections are made to 8 terminals within the enclosure:

1:  Input plus.
2:  Input 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).
