SCHNEIDER ELECTRIC A9XMWD20 PowerTag Link Wireless Concentrator

OverviewSCHNEIDER ELECTRIC A9XMWD20 is the Acti9 PowerTag Link wireless to Modbus TCP/IP concentrator gateway from Schneider Electric, designed for collecting measurement data from PowerTag wireless energy sensors. It supports up to 20 wireless PowerTag sensors, receiving RF data of voltage, current, power, energy and power factor, then converting and forwarding data via Ethernet Modbus TCP/IP to BMS, SCADA or power monitoring systems. It is equipped with an embedded web server for local parameter configuration and real-time data viewing. DIN rail modular installation fits inside Acti9 distribution boards for branch circuit energy monitoring and load alarm. This model is discontinued, with PAS400 as the recommended replacement, and it is supplied as spare stock for existing low-voltage monitoring retrofits.

FeaturesSCHNEIDER ELECTRIC A9XMWD20 adopts 2.4 GHz radio frequency communication to pair with PowerTag wireless sensors. The PowerTag Link Wireless Concentrator integrates one Ethernet port for Modbus TCP/IP server function and built-in web page commissioning; it supports basic energy metering and advanced load monitoring with alarm trigger. It has status LED indicators for power, link and wireless signal, and a reset button for factory restoration. It features 10 ms short power interruption immunity, low power consumption and compact modular housing. It complies with IEC 61131-2, RoHS and relevant low-voltage standards. Wireless pairing simplifies wiring and reduces engineering cost for multi-circuit monitoring. SCHNEIDER ELECTRIC A9XMWD20 is matched with Acti9 miniature circuit breakers fitted with PowerTag sensors for granular branch power monitoring.

Operating ParametersSCHNEIDER ELECTRIC A9XMWD20 ambient operating temperature: -25℃ ~ +60℃. The PowerTag Link Wireless Concentrator relative humidity: 5%~95% non-condensing. Pollution degree: 2. EMC: comply with low-voltage distribution IEC standards.

PrincipleSCHNEIDER ELECTRIC A9XMWD20 continuously receives wireless measurement frames transmitted by PowerTag sensors. The PowerTag Link Wireless Concentrator decodes electrical data, stores and organizes the data into Modbus register mapping, and responds to polling requests from upper monitoring hosts through Ethernet. Users can access the built-in web page to check readings, configure wireless pairing and set alarm thresholds. RF signal loss, Ethernet cable failure or internal circuit damage will cause SCHNEIDER ELECTRIC A9XMWD20 to stop uploading sensor data.

ApplicationsSCHNEIDER ELECTRIC A9XMWD20 is widely deployed in commercial buildings, data center branch distribution cabinets, factory workshop power panels and marine low-voltage distribution systems. The PowerTag Link Wireless Concentrator undertakes wireless data collection and protocol conversion for branch circuit energy monitoring, cooperating with PowerTag sensors and upper management platforms to realize load tracking, energy statistics and fault alarm. SCHNEIDER ELECTRIC A9XMWD20 is a preferred spare for legacy Acti9 wireless power monitoring system maintenance and replacement.
