Schneider 140NOM25200 DIO Head-End Adapter

Description

The Schneider 140NOM25200 DIO Head-End Adapter is a fiber optic head-end adapter belonging to the Modicon Quantum series programmable controller (PLC) product line. It is designed to connect digital signals from field devices to PLC systems, enabling reliable data transmission and integration in industrial automation setups. Key technical specifications include a 2mA current draw, 2ms filtering time, and logic states defined as 0V (low level) for logic 0 and 24V (high level) for logic 1. Its 32 digital inputs operate with 24VDC voltage, matching the logic state configuration, while the 32 digital outputs are voltage-type with a 24VDC range, 0.5A current capacity, and identical logic state settings. For communication, it supports the Modbus+RS485 protocol, with selectable baud rates including 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps. The unit runs on a 24VDC power supply, and features a compact, easy-to-install design with an IP20 protection rating, preventing access by solid objects larger than 12mm. It also meets international electromagnetic compatibility standards including IEC 61326-1:2015 (Class A) and IEC 61131-2:2017, ensuring stable performance in industrial environments.
