## Description

2-channel analog acquisition module for measuring 0-20mA and 4-20mA current signals, ideal for automation and instrumentation. Communicates via RS485 with Modbus RTU support for quick integration into PLC or SCADA. Operates at 8-25V DC, offers good resolution and typical 1% accuracy, in a compact, easy-to-mount format.
Analog current acquisition module 4-20mA and 0-20mA, N46IB02, with RS485 communication and Modbus RTU support, designed for simple and efficient integration in automation, instrumentation and measurement systems. The module is specially optimized for the standard 0-20mA and 4-20mA signals frequently used in automation and instrumentation.
In the DOWNLOAD section you can find more information about how to use this product.
It supports MODBUS RTU commands such as function codes 03 and 06, facilitating integration in control and automation systems.
The ID of the slave device can be set by commands, with a maximum number of 247, facilitating addressing and management in Modbus networks.
The MODBUS Command Module requires the correct configuration of the slave ID for efficient communications.
The specific limitations of this module are the fact that O1 has a minimum output voltage of 0.05V and O2 of 0.1V, as well as the presence of a high pulse of 10-20ms at the time of power supply
