The I/O power supply current to be supplied to the V and G terminals of each Digital I/O Slave Unit is provided
by the following equation.
The points to which I/O power must be supplied are divided into small blocks. The I/O power supply currents
supplied to these points are calculated in block units.
For example, in a CRT1-ID16TA Slave Unit, the points are divided into two blocks. One includes 8 points on the
left: Inputs 0 to 7. The other contains 8 points on the right: Inputs 8 to 15. Currents are calculated for each
block.
Input Unit
The I/O power supply current supplied to V and G terminals = input current (for number of points used) + cur-
rent supplied to input devices (for number of points used) * + I/O power supply current consumption
Output Unit
The I/O power supply current supplied to V and G terminals = rated output current (for number of points used)
* + current supplied to input devices (for number of points used) + I/O power supply current consumption
(Example)
Case of having seven 30-mA sensors connected to the CRT1-ID08TA
I/O power supply current supplied to V and G terminals = (6 mA x 7 points) + (30 mA x 7 points) + 5 mA =
257 mA
* This value does not apply to 2-tier terminal block type slaves.
* Compare with the restricted value for common and apply whichever value is the smallest.
Calculate using I/O power supply current supplied to V and G terminals = input current (for number of
points used) + I/O power supply current consumption.
