Analog I/O Units Section 7-4
Main Analog I/O Unit
Specifications
Analog I/O Units are connected to the CP1L CPU Unit. Up to seven Units can
be connected, including any other Expansion Units and Expansion I/O Units
that are also connected.
Note (1) The conversion time is the total time for 2 analog inputs and 1 analog out-
put.
(2) With analog outputs it is possible to use both voltage outputs and current
outputs at the same time. In this case however, the total output current
must not exceed 21 mA.
