4 CH AI/P 4-20MA S/END 12 BIT

4-channel analog input - 4-20 mA, Single-ended, 4 x 24 V


This analog input module processes standard 4–20 V signals. The input signal is electrically isolated and transmitted with a resolution of 12 bits.

The internal system supply powers the module. The input channels of the module have a common ground potential. The module provides a 24 V power supply for a direct connection to 2-wire sensors.
