1794-IE8H HART Enabled Analog 8 Input Module
The 1794-IE8H is a HART enabled analog input module that works with
HART enabled input sensors with input current in the 0…20 mA range. Use the
1794-IE8H with 2 or 3 wire transmitters. This module provides wire-off
detection on a per-channel basis. The HART analog module can only be used on
ControlNet or EtherNet/IP networks with one HART field device per channel.
1794-IE12 Analog 12 Input Module
The 1794-IE12 is a voltage or current measurement module that measures input
voltage in a ±10V range or current in the 0…20 mA range. Each channel is
individually configurable and the out-of-range notification is by channel.
