Eight-point Output Units (2-tier Terminal Block with Relay
Outputs)
CRT1-ROS08
Common Specifications
Relay Output Section Specifications (per Output)
Note
(1) With a current of between 2 and 3 A (8 to 10 A per common), either en-
sure that the number of points per common that simultaneously turn ON
does not exceed 4 or ensure that the temperature does not exceed 45
°
C.
There are no restrictions if the current does not exceed 2 A (8 A per com-
mon).
(2) The rated current is the value for assuring normal operation, and not for
assuring durability of the relays. The relay service life depends greatly on
factors such as the operating temperature, the type of load, and switching
