The OMNITERM THZ programmable four-wire Frequency Transmitter accepts a periodic or pulse wave-form signal such as from a proximity detector used to detect rotational speed, and provides an analogue or pulse train output signal relative to frequency.
OVERVIEW
The OMNITERM THZ four-wire Frequency Transmitter accepts a periodic or pulse wave-form signal such as from a proximity detector used to detect rotational speed, and provides a analogue output signal relative to frequency. This module uses advanced state-of-the-art digital measurement techniques, combined with extremely user friendly software configurability for best ease of use without factory required setup when ordering.
The input will accommodate pulses from dry contacts, open collector transistor outputs (NPN or PNP) and Namur standard ‘N’ type proximity sensors.
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.
Full isolation (input/output/power supply) to 1500Vac ensures trouble-free accurate measurement.
MINIMUM LIFE CYCLE COST
The OMNITERM THZ 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.
Using advanced digital filtering techniques, the THZ offers up to one hundredth of a Hertz resolution combined with fast response to changing signal frequencies.
MANAGING TRANSMITTER CONFIGURATION - THE EASY WAY
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.
HIGH RELIABILITY
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.
