Introduction

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.

To enhance the look of your ProtEX-MAX Annunciator, we strongly recommend you order Free custom message labels. These can be ordered at any time, just by filling out a convenient on-line form at Free Custom Message Labels.

General

Update Rate: 41 ms following alarm state; 1 ms for alarm state clear.
Sequences: Input follower, ISA Sequences A, F1A, F2A, F3A, M, F1M, and F3M per ISA Standard ISA-18.1-1979 R2004.
Sequence Options: A, F1A, F2A, F3A, M, F1M, F2M, and input follower with selectable options -1 (silence push button), -4 (no lock-in), and -6 (no horn) per ISA Standard ISA-18.1-1979 R2004

Relays

Rating: 2 SPDT (Form C); rated 3 A @ 30 VDC or 3A @ 250 VAC resistive load; 1/14 HP @ 125/250 VAC for inductive loads.
Electrical Noise Suppression: A suppressor (snubber) should be connected to each relay contact switching inductive loads to prevent disruption to the microprocessor's operation. Recommended suppressor value: 0.01 µF/470 Ω, 250 VAC (PDX6901).
Relay Operation: Relay 1: Alarm state until alarm is acknowledged. Relay 2: Alarm state if any channel indicating alarm condition.
Fail-Safe Operation: Programmable independent for each relay.
Note: In fail-safe mode, relay coil is energized in non-alarm condition. In case of power failure, relay will go to alarm state.

ATEX/IECEx Specific Conditions of Use:
  1. The equipment label and epoxy coating may generate an ignition-capable level of electrostatic charges under certain extreme conditions. The user should ensure that the equipment is not installed in a location where it may be subjected to external conditions (such as high-pressure steam) which might cause a build-up of electrostatic charges on non-conducting surfaces. Additionally, cleaning of the equipment should be done only with a damp cloth.
  2. Flameproof joints are not intended to be repaired.
  3. All entry closure devices shall be suitably certified as “Ex d”, “Ex t” and “IP66/68” as applicable. Suitable thread sealing compound (non-setting, non-insulating, non-corrosive, not solvent based, suitable for the ambient rating) must be used at the NPT conduit entries to achieve the IPx8 rating while maintaining the Ex protection concept.
