Allen Bradley 1756-IF8H Analog Input Module
This module features Eight differential voltage or current input channels and One Highway Addressable Remote Transducer (HART) modem. Each channel is configurable for 0-20 mA and 4-20 mA input signals while configurable voltage input signals are +/-10 VDC; 0-5 VDC; 1-5 VDC and 0-10 VDC. This module has a resolution of 16 - 21bits.The RPI parameter governs when an analog output module receives data from the owner controller and when the output module echoes data. An owner controller sends data to an analog output module once per RPI. Data isn’t sent to the module at the end of the controller program scan.
