Example selection

1. customers need WRe325 thermocouple signal input, output is 4-20MA transmit signal, relay as a newspaper.

For alarm purposes, the lower limit alarm temperature is 750 degrees, the upper alarm temperature is 1850 degrees, and the hand-held programmer is used.

The selection is as follows:

DK1000-WRE325-4MA20-A-Y-AL:750-AH:1850

2. customers need PT100 thermal resistance signal input, output is 0-10V voltage signal, output as communication DA to

The relay is used as a communication for a given switch quantity to output IO contacts. Other parameters are defaults.

The selection is as follows:

DK1000-PT100-0V10-D
