EB.AP-01 Intrinsically safe access point (EB.APG-01 main part and EB.APR-01 radio part)
EB.AP-01 is an intrinsically safe access point for reading data from an intrinsically safe wireless sensor network. EB.AP-01 consists of two parts: EB.APR-01, which is an antenna module that enables communication with each sensor at 2.4 GHz, and a main module EB.APG-01, which collects data from sensors and enables communication with the Ethernet network.
