Notes: 1) In case of connecting DC 2-wire output device to the input, a bleeder resistance R
IN.
2) Pin No.10 to 17 of the SL-VM8 will be the N.C. pins (non-connected pins).
3) Pin No.28 [ADD. (COM.)] is shorted to pin No.19 to 27 [ADD. (256) to ADD. (1)], and sum total of their address numbers will be the
first address.
4) Pin No.34 (0V), pin No.32 (G), pin No.30 (GND), and pin No.28 [ADD. (COM.)] are electrically insulated inside the unit. Do not short
these pins.
