(1) To comply with UL certification requirements, field power must be supplied from a single Class 2‐compliant power supply
(See Choosing a Power Supply on page 45 ) which limits available field power to 100VA. Therefore, the aggregate current of outputs
per module is limited to a maximum set by the 100VA limit (unless derated further as shown) for applications that require UL
listing.
(2) Maximum power dissipation applies when using 28.8V DC module supply and maximum power dissipated with all eight outputs in
the ON state.
(3) Typical power dissipation applies when using 24V DC module supply and nominal power dissipated with all eight outputs in the ON
state.
(4) Input off-to-on filter time is the time from a valid input signal to recognition by the module. Input on-to-off time is the time from a
valid input signal to recognition by the module.
(5) Use this conductor category information for planning conductor routing. Refer to the Industrial Automation Wiring and Grounding
Guidelines, publication 1770-4.1 .
