Electronics & automation systems provides programmable measuring transducers manufactured by lumel of poland. These transducers can be compatible with various input designed for continuous conversion into digital or analog standard signals for ac current and ac voltage, dc current and dc voltage, temperature, resistance, power, energy, power factor, angle, rpm, impulses, frequency, period, rotational speed, working hours, etc. They give outputs like two relay, analog and digital rs-485 modbus protocol programming output. The measured quantity by these transducers are displayed along with programmed unit symbol on the lcd display, 2 x 8 characters. They can be programmed, for 82 engineering units. The transducers have mathematical functions, like rising of power and extraction of roots. The advantages of these transducers is the possibility to program measuring inputs and outputs and alarms by means of the keyboard, through the programmer or through the rs-485 interface. Its specification includes that the programmable measuring transducers operate on 85 to 253 v ac / v dc or 20 to 50 v ac / v dc. They are housed in compact 35 mm din rail mounted design of size 45 mm [w] x 120 mm [h] x 100 mm [d].
