In your specific case, I would suggest a two-stage amplification. With the 1st amplifier to bring the signal (4-20mA) at 0-1000 units. With the 2nd amplifier (gain 1.47 (1000 x 1.47 = 1470)) came the sensor singal to the desired range. If you were from the start trying to reinforce the area with one amplifier to 0-1470, the amplifier block would spend a warning and it came out not exact values. Attachmentrpm.zip (321 Downloads) |

In attachment is an excerpt from the manual of Logo 0BA8. Perhaps this is understandable. AttachmentLOGO! 8 Soft manual 0BA8 2014_06_sides_130+131.pdf (268 Downloads) |
