This DIN rail mount programmable two-wire transmitter is designed for the widest range of signal conditioning applications in a single off-the-shelf product, using state-of-the-art digital measurement and filtering techniques.


Use the OMNITERM TWT for all your DIN rail mount two-wire signal conditioning needs.  The TWT is powered from the output current loop, and converts the dc signal input type and range of your choice to 4-20mA.

The OMNITERM TWT Universal Two-Wire Transmitter is designed for the widest range of signal conditioning applications in a single off-the-shelf product. Configuration to any input range can be done in minutes without the need any any special test equipment other than a personal computer.

Input types that can be configured by the user include thermocouple, resistance bulb, millivolts, volts and millamps.

This product 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.

Full isolation (input to output) to 1500Vac ensures trouble-free accurate measurement.


Using advanced sigma-Delta A/D technology combined with sophisticated digital filtering techniques, the TWT offers 16 bit measurement resolution with increased dynamic range, tailored for noisy plant environments, in a"surprisingly cost effective package".


Omniset, 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.

Calibration can also be checked while units are installed, without touching the wiring.


This product has been designed with high reliability applications in mind. The output stage has a unique built in overload indicator to detect overloaded output circuits - whether from a wire break or just excess resistance in the line.  This product has been certified to IEC61508 SIL1 safety standard and undergone Emphasis assessment for use in the UK Nuclear Industry.



The Omniterm TWT is part of the latest Omniterm range of signal conditioning modules.
