2.7.3 Discrete Input and Output Connectors

The Rackmount Controller is equipped with 4-pin, 8-pin and 9-pin terminal block connectors.
The 4-pin terminal block connector is designated for, but not limited to, interlock purposes. The
8-pin terminal block connector has a series of discrete inputs which can both control the
positioner or the digital discrete outputs from the 9-pin terminal block connector depending on
the position of the Positioner/Auxiliary Switch (see Section 3.6).
