OVERVIEW
The OMNITERM TFX Special Function Module is ideal
for those special applications where mathematical
computations are required on your analogue signals. The
TFX accepts two 1-5V (up to 1-10V) or 4-20mA inputs
and provides one universal output.
The output can be configured for unipolar or bipolar
outputs of current or voltage from ±1mA to ±10mA; 0
20mA; or ± 1V to ±10V, as well as pulse outputs for
totaliser and frequency translation applications.

as belt slip monitoring, dual-redundant analogue inputs,
ratio monitoring, rate -of-change monitoring etc. etc..

This module uses advanced state -o f-the-art digital
measurement techniques, combined with extremely user
friendly software configurability for best ease of use
without factory required setup when ordering .

HIGH RELIABILITY

Full output isolation to 1500Vac ensures trouble-free
installations .
MATHEMATICAL FUNCTIONS
The Omniterm TFX comes equipped with a wide
selection of common mathematical functions . When
combined with the user configurable 32 point linearisation
table, this powerful computation module can be used to
solve a wide range of signal processing applications such

LOW LIFE CYCLE COSTS
The OMNITERM TFX provides extremely low life-cycle
costs by reducing spares stock-holding requirements,
and reducing specialist technical expertise required for
field support, module replacement and field configuration.
This new holistic approach to instrumentation asset
management ensures reliable performance and minimal
down-time.
This product has been designed with high reliability
applications in mind. The output stage has built-in
overload indication to detect overloaded output circuits –
eg. from a wire break or excess resistance when
configured as a current loop, or too low a load resistance
when configured as a voltage output.
This product has been designed to meet the criteria of
IEC61508 for SIL1 applications.
