DATASHEET • Select from a wide range of computation functions • Fully configurable by the user • Accepts two 4-20mA or 1-10Vdc inputs • One universal 0-20mA / 0-±10V / 0-±10mA or pulse output • Output isolation to 1500Vac • Output overload detection • 24Vdc powered Features • • Select from a wide range of functions: Average, Deviation, Difference, Multiplication, Ratio, Minimum, Maximum, Track and Hold, Peak, Valley, Rate of Change, Ramp Limited, Log etc. 1500Vac Isolated Analogue Output Output overload Indicator User friendl y configuration software Wide operating temperature range DIN Rail or surface mountable Narrow 22.5mm module width Designed to meet IEC 61508 SIL1 criteria. 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. Copyright Omniflex ♦ Subject to change without notice
