Note:
• (*): ITotal_Loops_1_2_3 is the sum of
currents absorbed on Loops 1, 2, 3
• (**): ITotal_Loops_4_5_6 is the sum of
currents absorbed on Loops 4, 5, 6
• (***): ITotal_Outputs is the sum of the
currents drawn by the terminals SC1, SC2,
24A, 24R, 24V-RS485.
• (****): If the FC500IP module is not be
used then the relative amount of current
(100 mA) can be drawn from the SC1,
SC2, 24A, 24R, 24V-RS485 terminals.
