Schneider Electric AS-P890-000 PLC Product Details
Product Overview
Schneider Electric AS-P890-000 is a Modicon series remote I/O adapter and power supply module.It is mainly used to expand the I/O points of the PLC system and place the I/O module away from the PLC controller.The module provides power to the remote I/O module and communicates with the PLC through a single cable.
Main Features
Remote I/O Adaptation:Supports Modicon Modbus communication protocol and can connect a variety of Modicon remote I/O modules.
Power Supply:Provides 24VDC power supply for the connected remote I/O module.
Single Cable Communication:Communication and power supply with PLC are achieved through one cable,simplifying wiring.
LED Indicator:Provides status indication for easy fault diagnosis.
DIP Switch Configuration:The module address can be configured through the DIP switch to facilitate system integration.
Application Scenarios
Distributed I/O:In situations where I/O modules need to be distributed,such as large production lines and distributed control systems.
Harsh environment:Place the I/O module in a harsh environment close to the site to improve system reliability.
Expand I/O points:When the PLC’s I/O points are insufficient,the I/O points can be expanded by adding AS-P890-000 modules.
Technical parameters
Communication protocol:Modicon Modbus
Power input:120/220VAC
Power output:24VDC,0.5/0.25A
Operating temperature:-20℃to+60℃
