Analog Input Signal Connection

Analog signal input types are divided into single-ended input and differential input. This product uses
single-ended input fixed. The following examples show how to connect analog input signals using a

flat cable and a shielded cable.

Single-ended Input

The following figure shows an example of flat cable connection.

Connect separate signal and ground wires for each analog input channel on CN2.

Figure 3.5. Single-ended Input Connection (Flat Cable)

The following figure shows an example of shield cable connection. Use shielded cable if the distance
between the signal source and product is long or if you want to provide better protection from noise.
For each analog input channel, connect the core wire to the signal line and connect the shielding to

ground.

Figure 3.6. Single-ended Input Connection (Shielded Cable)

- If the signal source contains over 1MHz signals, the signal may effect the cross-talk noise between

channels.

- If the product and the signal source receive noise or the distance between the product and the

signal source is too long, data may not be input properly.

- An input analog signal should not exceed the maximum input voltage (relate to the product analog

ground). If it exceeds the maximum voltage, the product may be damaged.

- Connect all the unused analog input channels to analog ground.
- The signal connected to an input channel may fluctuate after switching of the multiplexer. In this

case, the cable between this product and the signal source can be shortened or a buffer with a

high-speed amplifier can be placed between the product and the signal source in order to reduce
the fluctuation.
