Multifunctional transducer MFU

(PresseBox) (Güglingen, ) If control projects involve both analogue measured values for detecting and controlling pressure, temperature and level and limit values for signalling, monitoring and controlling, multifunction transducers (MFUs) are the ideal solution. They are used in many industrial processes as well in applications such as plant engineering, well measurement, dosing and pressure control, filling systems, level and temperature monitoring, heating systems and air conditioning, laboratories, test facilities and control cabinet/switch rooms.

The new digital multipurpose transducers MFU 12 and MFU 14 from AFRISO are freely programmable digital transducers with two analogue outputs and 2 or 4 voltage-free relays, depending on the version. The standard version of the transducers and additional options allow you to implement solutions for almost all tasks involved in modern evaluation systems. The parameters are set either directly at the transducer or via the optional configuration software MFU 03-S, which is available with interface cable and USB adapter. The inputs are bipolar current and voltage inputs and a potentiometer input (3-wire technology). In addition, a 2-/3-wire transmitter supply is integrated. All inputs are galvanically isolated from the voltage and the current / voltage outputs. The two analogue outputs can be scaled separately and used simultaneously. For switching tasks, MFU 12 features 2 relay outputs; MFU 14 has 4 relay outputs (voltage-free changeover contacts, max. switch rating 250 V AC, 2 A and 50 V DC, 2 A). Selectable functions include energising/de-energising, hysteresis, window or trend as well as delays for energising/de-energising. The transducer MFU 12/14 has a DIN rail housing with integrated multicolour (R/G/B) lit LC display for the various operating modes. The lighting can be switched off. The values to be measured can be selected from a list including specification of range and unit or they can be configured and scaled as a user-defined unit with ranges from 0 to 9999 digits. The input resolution is 13 bits, the output resolution 10 bits. In addition, linearisations are possible via 24 free X/Y points and the modes "table, cylinder, sphere". Available user interface languages are English, French and German. The following additional functions are available: Error alarm in the case of missing or defective sensor, zoom function, spread, inverted mode, trend indication, learning mode measuring range, automatic or manual simulation, configuration lock, measurement signal monitoring with up to 4 freely adjustable limit values and programming interface. The new MFU 12/14 operates reliably in all supply voltage ranges AC (DC) 20-253 V, features plug-in, codeable terminal blocks and responds to numerous challenges in universal, safe measured value acquisition.
