2.1 Environment Conditions
(Note 1) "Short term" means within one month.
(Note 2) For the current value of the I/O circuit, calculate with the number of points used and load.
(Note 3) For the heating value of the I/O circuit, calculate with the number of points used.
(Note 4) Allows only the amount to be consumed by control circuit.
(Note 5) Differs according to the number of machine input operation points and the load and number of points
connected to the machine output. The maximum value applies when all points are ON.
(Note 6) These units, which are open equipments, must be installed within a sealed metal control panel.
(Note 7) FCU7-KB926 does not need 24VDC power supply input.
