External Input Signal (Dual use of DIN, RST Input Port)
• General Purpose Input (DIN)’s input level must be 1.5 seconds or longer to
be detected.
• Be sure the voltage value between terminals is controlled via the input volt-
age, so that the PS-B is operated within its recommended range. If the input
voltage exceeds this range, a malfunction or PS-B damage may occur.
• With Sink/Source input, even if DIN(-), and RST(-) are positive, and
DIN(+), RST(+) are negative, no problems are created. Be sure to oper-
ate the unit within the recommended voltage range.

When using No.2 (+5V) and No.3 (+12V) External Power Output, be
sure to use only the designated level of current. Not doing so could
couse a damage or a unit malfunction.
