The Standard Nine-Slot Rack for the IC697 programmable controller isused for all CPU and I/O configurations. Each rack has provision for one power supply at the leftmost module position; and either nine additional slot locations (nine-slot rack). Overall rack dimensions are 11.15H x 19W x 7.5D (283mm x 483mm x 190mm). Slots are 1.6 wide except the power supply slot which is 2.4 wide. Two racks can be interconnected to share a single power supply for applications having extended I/O requirements. A Power Supply Extension Cable kit (IC697CBL700) is available for such applications. Each rack provides slot sensing for rack-type I/O modules designed for the IC697 PLC. No jumpers or DIP switches on the I/O modules are required for module addressing.
