FDT5040: 4/20mA Input with Loop Excitation Supply
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)
Select from the above list according to your input range. Add suffix A (for example, FDT5000A) for AC power, D for DC power.
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).
Input Capabilities, Model FDT5060:
1mA minimum span, +/-5 Amps maximum input. Offset ranges are allowed. (Input voltage drop typically 0.1V at full scale.)
4mV minimum span, 1V maximum span (specify FDT5000 for spans greater than 1V.) Offset ranges are allowed. (Input Impedance: 200kohms or greater.)
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).
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.
+/-0.1% of span or 10 microvolts, whichever is greater.
Zero and span each are adjustable approx. +/-15% of span.
+/-0.05% of span or better.
Under 100 milliseconds.
3-way (Power/Input/Output) 1,500Vac rms (2,100V peak).
Guaranteed Operating Temperature:
-10 to +60oC (14 to 140oF).
+/-(0.02% of span plus 1.3 microvolts) per oC, or better.
