System structure and order numbers



Example1: NEED – 230AC – 01 – 08 – 4R
The NEED programmable relay– rated supply voltage 230V AC – version 01, programming port type A – 8 inputs – 4 relay outputs – without the possibility to add any extensions, an LCD display, inputs without galvanic separation.

Example2: NEED – 24DC – 11 – 08 – 4R
The NEED programmable relay– rated supply voltage 24V DC – version 11, programming port type B – 8 inputs – 4 relay outputs – without the possibility to add any extensions, an LCD display, inputs without galvanic separation


The programmable relay without display requires the use of a cable for programming and software diagnostic PC Need.
