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-ID215)
To prevent overheating in the C200H-ID215 that can cause early failure of internal components, limit the number of
input points that are ON simultaneously. As shown below, the number of points that can be on simultaneously
depends on both the temperature and the input voltage.
For example, 22 pts with input voltage of 24.0 VDC can be ON at 55°C, but only 16 pts with input voltage of
26.4 VDC can be ON at 55°C. At 24.0 VDC, all 32 input pts can be ON up to 43°C, but at 26.4 VDC all 32 input pts
can be ON up to 34°C.

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.
