2-3 I/O Units
There are two basic types of I/O Units available: Terminal block types and con-
nector types. Most of the I/O Units shown in the following table are terminal block
types. Only CQM1-OD213 DC Input Units (32 pts.) and CQM1-OD213 Transis-
tor Output Units (32 pts.) are connector-type I/O Units.
