What is the difference between C200H-ID216 Programmable Controllers’ input Units and C200H-ID218 Programmable Controllers’ input Units?


The C200H-ID216 and C200H-ID218 have different input impedances. The input impedance of each Unit follows.

C200H-ID218: 3.9 kΩ

C200H-ID216: 5.6 kΩ

Therefore, their input currents are also different.

C200H-ID218: 6 mA

C200H-ID216: 4.1 mA

Choose Units based on the leakage current of the connected devices.
