This expansion I/O module adds an analog input interface to the CPU unit of the CONPROSYS nano series. The CPSN-AI features a 12-bit or 24-bit resolution analog input. One module can be used as single-ended voltage input with 8 channels, differential voltage input with 4 channels, or differential current input with 4 channels. The functions can be switched.
Bus Isolated Analog Input
This module offers bus isolated analog voltage input and analog current input. As the analog input supports differential input, accurate measurement can be performed even when potential differences with the signal source occur.
Capable of supporting multiple input range and types.
It can support several input ranges. The input type can be switched between single ended input and differential input. Also, the range can be switched to current input of ±20mA, 0 -+20mA with the switch on the I/O module.
Easy installation and removal
This module can be installed in and removed from the CPU unit without any tools.
Adaptable to a wide temperature range between -20 and +60°C
The module works with temperatures between -20 and + 60°C. It can be installed in various environments.
No electrolytic capacitor
Without an electrolytic capacitor, which has a limited life, we are creating the product with a long-life cycle.
Digital Filter for 24-bit resolution
Slowing the speed of switching channels with software command removes high-frequency noises. Moreover, 50/60Hz noises can be removed by configuring the power noise removal mode.
