3. PRODUCT OVERVIEW
D ESCRIPTION AND I NTENDED U SE
The IFX-21 is a smart device for re-transmission, monitoring, and break out of EXACTUS
®
pyrometer communications in industrial environments. It continuously buffers pyrometer output
and makes the readings available to various isolated ports and protocols, including a user
defined passive 4-20mA analog signal.
C ERTIFICATIONS AND A PPROVALS

The IFX-21 is a DIN rail mountable plastic enclosure with a number of ports on its top, bottom,
and front. The top has two sets of 4 spring terminals and one RJ45 port. The bottom has one
set of 4 spring terminals and two RJ45 ports. The front has a clear polycarbonate door which
covers a 5 character display, 2 indicating LED’s, and a USB service port.

M OUNTING
The IFX-21 is intended to mount on a 35mm top hat style DIN rail (IEC 60715 TH35). To
ensure optimal performance the IFX-21 should be mounted on a grounded rail inside an
enclosure with the appropriate NEMA rating for the environment. Where appropriate cooling
air and/or radiation shielding should be installed to ensure ambient temperatures remain within
device operational limits (see Section 7.1).
In choosing a mounting location note should be taken that the device power, analog output,
and pyrometer ports are located on the top of the device while communications, both Ethernet
and Modbus, are on the bottom.

D EVICE W IRING
4.4.1. W IRE G AUGE
BASF recommends wire gauges of not less than 18AWG and no more than 12AWG. For
best results stranded wire should be tinned or crimped into an appropriately sized ferrule.
Ethernet connections may utilize either CAT5 or CAT5e cables, CAT5e is preferred
where available.
4.4.2. T ERMINAL BLOCKS
The power, analog output, and Modbus terminals use detachable spring-cage connector
blocks. To insert or release a wire, push in the tab as shown in Figure 5. Pin out
numbering listed below for all terminal blocks, see section 7.2 for related input/outputs.
F IGURE 5: W IRE RELEASE TAB
In some situations, it may be necessary to remove the entire plug assembly. This can be
done by pulling the connector down and away from the device. If a tool is used care must
be taken not to crush or pierce the plastic.

*The IFX-21 is natively a passive analog device, it will modulate incoming current but it
provides no voltage. If required the incoming power may be routed to also provide power
to the analog loop, though doing so will compromise the isolation of the analog loop.

5. DEVICE OPERATION AND SETUP
O VERVIEW OF C ONNECTION M ETHODS
An important feature of the IFX-21 is its support for daisy chaining multiple units together. In
Figure 8 examples are shown of the minimum connections necessary to receive temperature
readings over various protocols. In these examples 4 units are shown, however the
methodology would be the same for any number of units.
BASF recommends that only communication connections necessary to the application be
implemented. Redundant connections, such as utilizing both Modbus and Ethernet, should be
avoided unless they are for periodic service purposes only.

5.1.1. USB S ERVICE C ONNECTION
The USB port is intended for setup and maintenance of the IFX-21. It may be utilized for
the short term collection of readings from a connected pyrometer. Long term data
collection is not recommended. Windows 10 is recommended for all USB service port
connections.

Pyrometer. While the TemperaSure pyrometer management software is running this display
will switch to either the user entered channel identification text or the pyrometer serial number.
For complete alphabet mapping and standard messages see Appendix 7 Segment Display
Alphabet.
Note: Last Segment decimal point flashes when data is received from pyrometer.

Configuration of the IFX-21 allows a user to change the device IP address, set custom
ambient temperature alarms, and adjust the pyrometer supply voltage.
Analog output settings and advanced operation modes, such as peak picking or variance
mode, must be configured within the Pyrometer. Please see the EXACTUS Optical
Thermometer User Manual for more information.

 Analog output is enabled.
 Instrument Ambient Alarm will trigger when internal IFX-21 electronics
temperature goes above 70ºC (158ºF). [NOT ENABLED]
 Instrument Ambient Alarm will trigger when Pyrometer internal electronics goes
above 60ºC (140ºF). [NOT ENABLED]
 The Pyrometer Supply Voltage is set to 6.2V – adequate for standard pyrometer
power/communication cables up to 15 meters (50 ft).

Failure to follow the instructions and specifications contained in this user manual may result in
impaired device function.
Use of an EXACTUS
®
pyrometer without an EXACTUS
®
retransmission device, such as the
IFX-21 or IMF8, may degrade measurement quality.
