I will use the analog current input module. Can I input a single input signal to two CHs of the module simultaneously (in parallel) to use them?

Answer
No, you can't.
The relationship between i, which is the sensor output current, and i1 and i2, which are the CH input currents of the PLC, is expressed as i = i1 + i2. The values of i1 and i2 are not the same due to the variation between parts so that it is impossible to input a proper value.
