Terminal Block Arrangement
SSI Input Units use screwless clamping terminal blocks.
This section describes the terminal block arrangements of the Units.
This section provides diagrams of the terminal block arrangement and internal power supply wiring of
the One-input Unit. It also provides a wiring example.
A 12-terminal terminal block is used.
Note The SSI power supply output (24 V and 0 V) is provided power from the I/O power supply connected to the
Communications Coupler Unit or an Additional I/O Power Supply Unit.
