When the output is in standby the NO and C terminals are open. When the
output activates, the relay changes to close the NO and C terminals.
The maximum rating per active output is 2 A at 30 VDC.

Connecting standard supervised outputs
All standard supervised outputs require a 15 kΩ, 5%, 1/4 W end-of-line resistor
as termination for proper detection of wiring problems (open or short circuit). If an
output is not used, the end-of-line resistor must be installed across the unused
terminals.
Figure 6: Control panel standard supervised outputs
Standard supervised outputs provide −11 VDC in standby and +24 VDC when
active (nominal values). Refer to the Outputs section of the Technical
Specifications chapter for the details on the maximum current rating.
