Note 1. Refer to the Unit’s Operation Manual for details on I/O bit allocation.
2. The Unit will have 128 dynamic output points when pin 1 of it’s DIP switch is ON.
3. Each output terminal has an output resistance of 4.7 kΩ.
4. At high temperatures, the number of inputs that can be turned ON simultaneously is limited. Refer to the
graph on page 150 for details.
5. The user is not authorized to change the fuse.
6. When wiring output circuits, be sure to use the correct polarity for the external power supplies. Wiring
with incorrect polarity may result in erroneous operation of the load.
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.
