FLEXIBLE COMMUNICATIONS
The 870ITPH is available in two different
communications platforms. For users who need only
transmit a 4 to 20 mA analog output without the
requirement for remote digital communication, a
transmitter with analog output only (Model Code
Selection “–A”) is available. Complete configuration,
calibration, status checking, and fault identification is
through the local human interface only.
For applications where remote communication is
required, a digital platform is available (Model Code
Selection “–F”). Within this digital environment, two
kinds of communications are selectable. First, the
transmitter may operate in a low speed (600 baud)
digital mode with the digital signal superimposed
over an analog 4 to 20 mA signal. Second, the
transmitter may operate in a high speed (4800 baud)
digital only mode. Communications with this digital
version may be via one of three methods - local
human interface, Foxboro PC-based configurator
interface, or I/A Series System Workstation. Any of
these methods allows complete configuration,
calibration, status checking, and fault identification.
When operating in either of the two digital modes,
the transmitter continuously delivers three
measurement values, namely temperature
compensated measurement, uncompensated
(absolute) measurement, and temperature.
The 4 to 20 mA output is scalable and
programmable as either normal or reverse acting.
The user can assign the output to one of three
parameters – temperature compensated
measurement, uncompensated (absolute)
measurement, or temperature.
Several selections of output damping are available
ranging from 1 to 120 seconds. An output HOLD
feature, easily accessible from the user interface,
allows the output(s) to be frozen at user-defined
value(s) to facilitate calibrations or sensor
maintenance while not disturbing the control loop.
SENSOR AND TRANSMITTER DIAGNOSTICS
When used with Foxboro DolpHin Series, and
applicable 871PH and 871A pH/ORP, and EP460
Series sensors, the 870ITPH delivers a multitude of
sensor diagnostics. These include:
Broken Glass Electrode
Aging Glass Electrode
Liquid Leakage into Sensor Body
Failure of High Impedance Preamplifier in Sensor
Failure of Temperature Compensation Element
Excessive Coating of the Reference Electrode
In addition to sensor diagnostics, the transmitter
continuously performs health checks on its own
circuits. In the event of a fault in the system, one of
three messages appears on the local display:
“PROBE ER”, “XMTR ER”, or “CONFIG ER”. This top
level message reporting allows the user to quickly
isolate the problem to either the sensor or the
transmitter. For additional information about the
specific fault or faults, the user need only access the
“DIAG” key and follow the prompts. Not only does
this procedure identify the specific faults, but it also
guides the user to a corrective action without
referring to an instruction book.
PSS 6-1B1 B

LOCAL, HUMAN INTERFACE
second line of the display. A secondary measurement
(temperature, absolute mV, or output in mA) which is
user-configurable, is shown on the third line of the
display. The display characters are 15 mm (0.60 in)
high, and allow easy reading from a distance.
The local human interface allows full configuration,
calibration, and fault location without the need of a
hand-held configurator. The interface consists of a
3-line LCD display and a keypad with eleven tactile
keys. Refer to Figure 1.
The 3-line display provides a digital bar graph (which
is activated while in the MEASURE mode) at the top
and two lines of alphanumerics. The bar graph
comprises twenty segments and indicates %-ofrange of the 4 to 20 mA output. When in the CAL,
CONFIG, STATUS, or DIAG mode, two segments are
lit to indicate the present mode of operation. The bar
graph also “zips” to confirm that a configuration entry
has been accepted.
The second and third lines of the display are the
alphanumerics relating to measurement values,
measurement error indications, message reporting,
and configuration and calibration prompts. These
prompts simplify programming the transmitter and
greatly reduce the need for instruction manuals. The
primary measurement (e.g., pH) is shown on the
20-SEGMENT BARGRAPH
FOR OUTPUT % OF SPAN.
CAL
INTELLIGENT CALIBRATIONS
Calibration routines are designed for simplicity and
elimination of errors. All procedures are selfprompting. Two calibration routines are available. A
“manual” calibration is for users who prefer to edit
and enter the pH values of their buffer solutions, and
an “automatic” calibration that provides a bufferrecognition mechanism which locks in on the buffer
value most closely representing the combination of
millivolts and temperature values being reported from
the sensor. User-programmable stability parameters
prevent the transmitter from accepting calibration
data until both the pH and temperature signals from
the probe have stabilized. Three tables of buffer
values are preprogrammed in the transmitter. For
flexibility, a custom buffer table may be userprogrammed for unusual application requirements.

SECURE DATA AND CALIBRATIONS
INTRINSICALLY SAFE DESIGN
Multiple levels of security protect against
unauthorized configuration/calibration changes, loss
of data, and/or invalid measurement signals. Two
levels of passcode protection are provided. The first
level permits access to routine maintenance
functions, including calibration and output hold.
The 870ITPH Transmitter is designed for compliance
to FM, CSA, and ATEX standards for intrinsically safe
and nonincendive apparatus in hazardous locations.
Refer to Electrical Safety Specifications section.
The second level permits changes to configuration
parameters by authorized personnel. Data is stored
in EEPROM, obviating the need for battery backup.
Measurement loop security is enhanced by a user
programmable “fail signal” parameter activated by
any transmitter fault and certain serious sensor faults.
This “fail signal” parameter forces the transmitter
output to any user-defined value between 3.8 and
20.5 mA (or equivalent percentages of full scale when
operating with digital communications).
Housed in a tough, epoxy-painted cast aluminum
housing, the 870ITPH is designed to withstand the
harshest field conditions. The enclosure provides the
environmental and corrosion-resistant protection of
NEMA 4X, CSA Enclosure 4X, and IEC IP65. It also
protects against RFI and EMI. Its efficient DIN panelsize design allows easy mounting for panel, pipe, or
surface applications. A hinged front door provides
easy front access to field connections. Large spade
lug terminals for sensor and communications
connections facilitate quick maintenance and
calibration procedures. The keypad overlay is
constructed of polycarbonate material.
QUICK AND INFORMATIVE STATUS
At the touch of a single key, the user gains access to
all the information necessary to assess the
performance of the pH loop. Among the parameters
this “read only” key accesses are:
Process Temperature
Slope of pH Sensor
Absolute (Uncompensated) Millivolt Value from
pH Sensor
Analog Output Value in Milliamps
Status of Glass Electrode
Asymmetry Potential
Resistance of Reference Electrode
Resistance of Temperature Compensator
Date of Last Calibration
RUGGED FIELD-MOUNTED ENCLOSURE
The transmitter can also be provided with an optional
polycarbonate storm door to prevent accidental
activation of the front panel controls.
APPLICATION FLEXIBILITY
Microprocessor technology, coupled with a simple
user interface, allows rapid customization of the
transmitter to specific application requirements. ORP
or ISE applications can be handled by simply
reconfiguring the basic pH transmitter to the desired
measurement. Temperature compensation is equally
as flexible, as the transmitter offers the standard
Nernst compensation for glass pH electrodes, as well
as optional solution compensation for pure water and
user-defined transforms.
PSS 6-1B1 B
Page 5
COMPATIBLE WITH WIDE RANGE OF
SENSORS
The transmitter contains an integral high impedance
preamplifier, thus permitting it to be used with
virtually any glass pH or noble metal ORP sensor.
Also, the transmitter can be programmed to accept
any of the three common temperature compensator
inputs – 100 Ω platinum RTD, 1000 Ω platinum RTD,
and Balco 3000 Ω RTD. This facilitates the use of the
870ITPH with many common non-Foxboro pH and
ORP sensors. When a nonpreamplified sensor is
used, the Foxboro sensor cable length is limited to
15.2 m (50 ft). Where the distance between the
sensor and transmitter is greater than 15.2 m (50 ft),
the Foxboro 871PH and 871A pH/ORP sensors are
offered with integral preamplifiers, thus allowing the
cable length to extend to 152 m (500 ft). See Figure
2 for Foxboro sensors compatible with the 870ITPH
Transmitter.
