I/O in the flow computer comes from the integrated multivariable sensor and RTD connector, the
CPU board, as well as from the optional 6-channel expansion I/O board.
Note
When using a digital output to drive an inductive load (such as a relay coil), place a suppression diode
across the load. This protects the DO from the reverse Electro-Motive Force (EMF) spike generated
when the inductive load is switched off.
