The ProtEX-MAX PD8-150 offers all the functionality of the Vigilante II PD150 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It provides alarming and monitoring capabilities for all of your level, pressure, flow, and other process switches. These explosion-proof alarm annunciators are available in two models; the PD8-154 has four (4) inputs and the PD8-158 has eight (8) inputs. Each model accepts inputs from relays, float switches, digital outputs, and many other discrete (on/off) devices. They can be field programmed for all common ISA alarm sequences including first out indication and provide alarm signaling through front panel LEDs and a built in 85 dB horn. The silence, acknowledge, and reset functions can be operated without opening the housing by using the built-in SafeTouch® through-glass buttons. Custom printed message labels can be included with your order at no additional charge.
