The galvanically insulated interface is an associated intrinsic safety item of equipment that is installed in a safe zone or in zone 2 in an IP 54 housing, thanks to the Ex nA protection mode. Its mission is to limit the level of energy that may appear in an electric circuit routed through a potentially explosive area, whatever the connection established upstream.
In addition to its energy-limiting function, its facilitates the use of signals in safe areas (e.g., relays), converts signals (e.g., 4/20 mA to 0-10V) or duplicates signals. Other functions are also available, such as the threshold relay or powering intrinsic safety.
Programmable converter BPX Universal input (TC, RTD, mA, mV,V, Potentiometer) Output : 2 trips and 4/20 mA Power supply : 110 to 230 Vac Mounting : Din rail
