High-density I/O Unit Limitations
Limitations on the switching capacity of C200H-OD215/MD115/MD215 Transistor Output Units and the usable
number of I/O points in the C200H-ID215 and C200H-MD215 are shown below.
Switching Capacity
The switching capacity of C200H-OD215/MD115/MD215 Transistor Output Units depends on the power supply
voltage, as shown below.
Usable I/O Points (C200H-MD215)
To prevent overheating in the C200H-MD215 and prevent early failure of internal components, limit the number of
input points ON simultaneously. The number of points that can be on simultaneously depends on both the temper-
ature and the input voltage. (There is no limit to the number of output points that can be ON simultaneously.)
Note If the Unit is at room temperature it takes about 10 minutes for excessive heat to build up when all inputs are
turned ON, so all inputs can be turned ON simultaneously for testing.
