NI204AI is an analog module tension designed to connect analog inputs to a Modbus system. The analog module incorporates a 3-way galvanic isolation and RS485 circuits.

Category: SKU: 5NIZ4AI

NI204AI, the analog module, is designed for interfacing analog inputs, specifically voltage or current (including bipolar range), with a Modbus system. These modules have the capability to supply all 4 current loops simultaneously, making them particularly convenient for 2-wire sensors that do not require an external power supply.

NI204AI acts as a Modbus Slave and can be easily paired with any Modbus Master device. Additionally, users can benefit from the 3-way galvanic isolation provided among the power supply, input, and RS485 circuits, ensuring the integrity of their data. In summary, NI204AI serves as an analog module for tension, an analogic module, specifically designed for connecting analog inputs to a Modbus system.
