1 GENERAL SPECIFICATIONS AND PRECAUTIONS FOR USE OF I/O
MODULE
POINT
(1) When using the module for the application in which the relay contact is
frequently switched, the relay life span should be considered. Therefore, it is
recommended to use a triac output module.
(2) The relay life curve shows the value based on actual use, which is not
guaranteed. Therefore, make sure to allow for a margin of error.
The relay life span differs according to the specifications as follows:
• Rated switching voltage, current load 100 thousand times
• 200VAC 1.5A, 240VAC 1A (COS
=0.7) 100 thousand times
• 200VAC 0.4A, 240VAC 0.3A (COS
=0.7) 300 thousand times
• 200VAC 1A, 240VAC 0.5A (COS
=0.35) 100 thousand times
• 200VAC 0.3A, 240VAC 0.15A (COS
=0.35) 300 thousand times
• 24VDC 1A, 100VDC 0.1A (L/R=7ms) 100 thousand times
• 24VDC 0.3A, 100VDC 0.03A (L/R=7ms) 300 thousand times
