Product Description

 

B.1 Product introduction

The wireless communication terminal of ESI-309 overhead fault indicator is mainly used to realize the communication between overhead fault indicator and remote server. As a communication bridge between fault indicator and remote server, ESI-309 wireless communication terminal is always in working state. On the one hand, it waits for fault indicator to upload data, on the other hand, it maintains real-time communication with remote server, and uploads all data information to remote server. ESI-309 wireless communication terminal uses 6.2 V rechargeable lithium iron phosphate battery as power source. The power comes from external solar panels.
