Safety-related Digital Outputs
The module has 16 digital outputs (DO1…DO16) whose status is indicated via status indicators.
An output is in a safe state when it is de-energized. If a fault occurs, all outputs are turned off.
Each of the 16 outputs can have a load of 1 A at the ambient temperature of 60 °C (140 °F) or up
to 2 A at a maximum temperature of 40 °C (104 °F). Because of heat dissipation concerns,
Rockwell Automation recommends loading only every other output at 2 A.
When an overload occurs, the overloaded outputs are turned off. When the overload is
eliminated, the outputs are activated again according to the specified value.
Although the external line of an output is not monitored, a short-circuit will be indicated.
Digital Output Terminals
Terminals accommodate wires up to 1.5 mm
2
(16 AWG). See the terminal torque specifications
on page 11 . Digital outputs (DO) are connected to these terminals.
