Q
Limitation on the number of simultaneous ONs
(1) Use the same power supply for the external power supply (to the +V terminal) and for
the load power supply. Use of different power supplies could result in the module
malfunctioning.
(2) The operating ambient temperature and the load current pose the limitation, shown
below, on the number of simultaneous ONs for this module. Attempted use past this
limitation will degrade the product life.

Load condition: 1.6 A/common
(*) The number of simultaneous ONs is the sum total of the number of ON inputs and
outputs.
With simultaneous ONs limited to 32, for example, the following combinations are
possible:
①
All inputs ON + All outputs OFF
②
All inputs OFF + All outputs ON
③
16 inputs ON + 16 outputs ON
④
20 inputs ON + 12 outputs ON
and so on
