Appendix G: 4-20mA EXP Analog Input Module (420EXP)
The 420EXP has 8 identical channels for loop powered non-IS
sensors with a 4-20 mA interface. The T5 series can support up
to 24 inputs (3 modules total including 420IB models with 8 inputs
each) depending on available space in your console. The 420EXP
will most likely be used with explosion proof version of the line leak
pressure transducers at the sites where IS wiring is not available.
It can also be used with other 4-20 mA sensors located in non-
hazardous area.
Note: Components located in the hazardous area must be an
explosion proof version and wiring must be enclosed in explosion proof conduits.
