PD8-150 ProtEX-MAX Explosion-Proof Alarm Annunciators

The ProtEX-MAX PD8-150 series offers easy-to-use explosion-proof annunciators that can be set up to respond to alarm conditions based on 8 field selectable alarm sequences, including first-out indication.

With either 4 or 8 switch inputs, the alarm channels accept normally open, normally closed, NPN open collector transistor, and logic level inputs.

The annunciator is housed in a field-mountable, NEMA 4X/IP68 rated enclosure available in either aluminum or stainless steel for convenient indoor and outdoor installation.

Three front panel pushbuttons are used during sequence operation to silence the audible alarm, acknowledge the first out alarm, and reset cleared channels as required by the sequences.

These functions can also be operated from hazardous-area remote devices using the remote control signal connectors, or in hazardous areas using the SafeTouch through-glass buttons.

The ProtEX-MAX PD8-150 series has two SPDT relays that can be used for additional external alarm indication, additional audible devices, or for process control.
