The Isolated AC Output modules, utilized in either an I/O
Rack or Model 60 CPU to provide switching capabilities
between user AC power supplies and user loads, are
available in two versions: 115V AC and 230V AC. The
Isolated AC Output module features and benefits are summarized in Table 1.
ON state. All six outputs are updated by the CPU during
an I/O scan.
A pair of indicators, visible through module faceplate, are
associated with each output: one displays the status of the
circuit fuse; the other iights when the circuit coil is
The modules include six optically-isolated outputs; each
output circuit employs a TRIAC as a switching device to
connect the corresponding output terminal to the highside of the user power supply when the output is in the
