2 CH AI/P 4-20MA S/END

2-channel analog input - 4-20 mA, Single-ended, light gray


This analog input module powers field-side signal conditioners and transmits electrically isolated analog signals to the bus system. The 24 V field supply is derived from the module's power jumper contacts.

The shield directly connects to the DIN-rail. This module powers 2-wire signal conditioners without dedicated power supply.
