*1 The cable-side connector is not provided with Units equipped with cables. Purchase the cable separately
(Refer to 5-3-3 Wiring Basic I/O Units with Connectors.), or use an OMRON Connector- Terminal Block Con-
version Unit or I/O Terminal (Refer to 5-3-4 Connecting to Connector-Terminal Block Conversion Units or I/O
Relay Terminals.).
*2 Although 16 I/O bits are allocated, only 8 of these can be used for external I/O. This Unit is also treated as a
16-point I/O Unit in the I/O tables.
