Notes:
2. JZ20-UN20/ JZ20-J-UN20 and JZ20-UA24/ JZ20-J-UA24 comprise I0-I8; these inputs
are arranged in a single group. Via wiring, the entire group may be set to either pnp or
npn.
3. JZ20-UN20/ JZ20-J-UN20 and JZ20-UA24/ JZ20-J-UA24 comprise I9 & I10. These
may be wired as either digital or analog inputs, as shown in the
JZ20-UA24/ JZ20-J-UA24 and JZ20-UN20/ JZ20-J-UN20 Installation guides.
I9 & I10 may be wired as npn, pnp, or 0-10V analog inputs. one input may be
wired as pnp, while the other is wired as analog. If one input is wired as npn, the
other may not be wired as analog.
