Discrete I/O
The internal solid state Discrete Input/Output options provide four inputs and six outputs. A harness
connects the main board of the IND560x to the Discrete I/O option board. The Discrete I/O option is
available in three different versions with different active/passive combinations:

•
The installation of the I/O option board is the same for all versions and is shown in detail in the
installation instructions included with the option kit.
In the harsh enclosure, the Discrete I/O option installs into the rear of the enclosure. Three plastic
standoffs are installed onto three fixed studs. The I/O board is then secured with screws onto the
standoffs as shown in Figure 3-34.
