Make sure that the power supply from the Communication Unit to the I/O Units is
less than the total rated output current (300 mA). The I/O interface current
consumption for each I/O Unit is shown in the following table.
I/O Unit
I/O interface current consumption
GT1-ID16(-1)
35 mA max.
GT1-ID16MX(-1)
35 mA max.
GT1-ID16ML(-1)
35 mA max.
GT1-ID16DS(-1)
35 mA max.
GT1-ID32ML(-1)
55 mA max.
GT1-OD16(-1)
35 mA max.
GT1-OD16MX(-1)
35 mA max.
GT1-OD16ML(-1)
35 mA max.
GT1-OD16DS(-1)
35 mA max.
GT1-OD32ML(-1)
65 mA max.
GT1-ROP08
40 mA max.
GT1-ROS16
50 mA max.
GT1-AD04
50 mA max.
GT1-AD08MX
50 mA max.
GT1-DA04
50 mA max.
GT1-DA04MX
50 mA max.
GT1-CT01
90 mA max.
Calculation Example
When three GT1-ID32ML Input Units and three GT1-OD16 Output Units are
used, the total current consumption is calculated as follows:
(GT1-ID32ML current consumption) x 3 Units
+ (GT1-OD16 current consumption) x 3 Units
= 55 mA x 3 + 35 mA x 3 = 270 mA
≤
300 mA
The addresses of the I/O Units on the I/O Unit interface are automatically set
when the Communication Unit is started. The addresses are from 0 to 7 in
ascending order from the I/O Units closest to the Communication Unit.
The following two methods are used to check the I/O Unit interface status:
•
Checking the Communication Unit and I/O Unit indicators
•
Checking the status of the Communication Unit
