Note The residual voltage in the PC is 4.0 V for the following Units:
For standard I/O Units:
The previous calculations are based on the following equations.
When using a two-wire sensor with a 12-VDC or 24-VDC input device, check
that the following conditions have been met. Failure to meet these conditions
may result in operating errors.
The residual voltage is 1.5 V for all other Units.
