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.
