Appendix 4: 4-20mA Analog Input Module (420IB)
The Analog Input Module has 8 identical channels for loop powered
IS sensors with a 4-20 mA interface. The T5 series can support up
to 24 inputs (3 modules with 8 inputs each) depending on available
space in your console. The Analog Input Module will most likely be
used with: line leak pressure transducers, tank pressure sensors
and vacuum sensors.
