There are a wide variety of Analog I/O modules available for use with the DL405
family of automation products. These modules are well suited for monitoring and
controlling various types of analog signals such as pressure, temperature, and so
forth. No complex programming or module setup software is required. Simply install
the module, add a few lines to your RLL program, and you're ready!

Analog input, temperature input and analog output modules are available. Most of
these modules are designed and manufactured by FACTS Engineering. FACTS has
been producing feature-packed products for the DirectLOGIC families (and
compatible products) for years! These modules are readily identifiable by their F4–
prefix in the part number.
The DL405 Analog Modules use an on-board microcontroller that automatically
monitors module diagnostics. You can easily detect missing field-side supply 24
VDC voltage or a loose terminal block.
