(1) To comply with UL certification requirements, power must be supplied from SELV compliant power supply (See Choosing a Power
Supply on page 47) which limits available field power to 150 VA. Therefore, the aggregate current of outputs per module is limited
to a maximum set by the 150 VA 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 four outputs in
the ON state.
(3) Typical power dissipation applies when using 24V DC module supply and nominal power dissipated with all four outputs in the ON
state.
(4) Use this conductor category information for planning conductor routing. See the Industrial Automation Wiring and Grounding
Guidelines, publication 1770-4.1
