CIRCUITRY
Two choices of switching speed vs. leakage cur-
rent are offered. In applications where both AC
and DC must be switched with the
same module, use 70-ODC5R, 70M-ODC5R or
70G-ODC5R. These parts are dry contact relays
in an I/O module shell. All other part numbers
provide solid state switching.
DIMENSIONS
For complete dimensional drawings, see pages
29-30.
