*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.
*3 An Interrupt Input Unit can be connected only in a CJ-series CPU Rack. When using the CJ2H-CPU@@-EIP,
connect the Interrupt Input Units in slots 0 to 3 in the CPU Rack. An I/O setting error will occur if the Unit is con-
nected in other positions in the CPU Rack or to any position in an Expansion Rack. Up to two Interrupt Input
Units can be connected.
