Huawei 210231455 EMUA embedded environment monitoring unit for base station/cabinet sites. Tech-Star (UK-based, shipped worldwide) – enquire for stock.

The Huawei 210231455 is an EMUA (Embedded Environment Monitoring Unit), documented across Huawei’s own EMU user guide and multiple telecom equipment resellers as a monitoring module used in Huawei base station and cabinet installations. The EMUA supports input voltage detection with two protected power input ports, and provides two RS-485 ports used for communication between the EMUA and the host BTS/NodeB or cabinet controller. It also provides an independent +12V/+24V DC current-type (4mA-20mA) port for humidity and temperature sensors, monitoring a temperature range of -20C to 80C, giving site engineers visibility of cabinet environmental conditions such as power status, temperature and humidity. EMUA units are used across a range of Huawei site infrastructure where environmental alarms need to be reported back to the network or site management system. Genuine units are recovered from decommissioned or upgraded sites and tested before resale, since new manufacture of this legacy module has ceased. Tech-Star (UK-based, shipped worldwide) stocks EMUA environment monitoring units including the 210231455. Please enquire for current stock and pricing.
