FOXBORO 870ITEC-AYFNZ-7

Description

Specifications
Sensors:
The 870ITEC Transmitter can be used with any 871EC Series Electrodeless
Conductivity Sensor or 871FT Series Flow-Through Sensor. They can also be used with
other electrically compatible sensors by entering the cell factor as part of the configuration
procedure.
Maximum Distance Between Sensor and Transmitter: 30.5 m (100 ft)
Temperature Compensation Inputs:
100 ohm platinum RTD
1000 ohm platinum RTD
100 kilohm thermistor
Ambient Temperature: -25 to +55°C
Relative Humidity: 0 to 95% noncondensing
Electromagnetic Compatibility (EMC): The Model 870ITEC Intelligent Transmitter complies
with the requirements of the European EMC Directive 89/336/EEC when the sensor cable and
I/O cables are enclosed in rigid metal conduit. (See Table 2.)
Power Supply Requirements (for 4 to 20 mA Output): 12.5 to 42 V dc (See Figure 2)
Wiring
Your 870IT is a 2-wire transmitter. As such, it transmits output over the same two wires through
which it receives power. If your transmitter was specified with analog communications
(870ITEC-A), you must supply its power source. If it was specified with digital communications
(870ITEC-F), power can be provided via the I/A Series Fieldbus Module. Connect this
power/output signal and the signal from your measurement sensor as follows:
1. Open the hinged case door.
2. Remove the plastic shipping caps from the openings on the bottom of the case and
replace with proper fittings. You will be running wires through the left and right
openings and capping the middle opening.
