■
Input derating: The PLC can operate with full load at ambient
temperature of 45℃. Derate the number of ON input points to 75%
(lower than or equal to six ON input points) at ambient
temperature of 55℃. Derate the number of ON input points by
2.5% for every additional 1℃ above 45℃.
■
Output derating: The PLC can operate with full load (total current
of eight output points not exceeding 2 A) at ambient temperature
of 45℃. Derate the total output current of ON output points to 50%
(total current of eight output points not exceeding 1 A) at ambient
temperature of 55℃. Derate the total output current of ON output
points by 5% for every additional 1℃ above 45℃.
● When installed non‑horizontally: The maximum number of input points
connected cannot exceed six, the maximum output current cannot
exceed 1 A, and the number of modules cannot exceed six.
