Models T16.x-AI
The intrinsically safe sensor circuit (optional 2-wire, 3-wire or 4-wire configuration) for both
versions is intended for the supply of equipment in areas with 1G or 1D requirements.
The version T16.H-AI has been designed for installation in cases or connection heads in
areas with 1G, 2G or 1D, 2D requirements.
The version T16.R-AI is intended for installation in a case which guarantees at least IP20
ingress protection (2G application or installation outside the hazardous area) or IP6X
(2D application).
