The Omniterm TFX special function module is suitable for those special applications where mathematical computations are required on analog signals. The TFX accepts two 1-5 V or 4 to 20 mA inputs and provides one universal output. The device comes equipped with a wide selection of common mathematical functions. A user configurable 32-point linearisation table enables TFX to solve a wide range of signal processing applications such as belt slip monitoring, dual-redundant analog inputs, ratio monitoring, rate-of-change monitoring etc.
* Select from a wide range of computation functions.
* Fully configurable by the user.
* Accepts two 4 to 20 mA or 1 to 5 V d.c. inputs.
* One universal 0 to 20 mA/0 to +10 V/0 to +10 mA.
* Output isolation to 1500 V a.c.
Solutions for:
* Integration (pulse output).
* Square root integration.
* Hi/Lo follower.
* Multiply/divide or ratio.
* Deviation monitoring - absolute value.
* Average value.
* Linearisation (square root, log 10, Ln, Sin, Cos).
* Rate function - ramp limiter and rate of change.
* Track functions - track and hold, peak and valley.
Configuration management
The powerful but intuitive configuration software ensures the maximum instrument flexibility with reliable configuration management to ensure all instruments on the plant are always correctly configured to the design requirements specification.
