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 audible horn. Additional audible devices may be triggered through the use of relays. 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 by completing this form.

Fuse: Required external fuse: UL Recognized, 5 A max, slow blow. Up to 6 annunciators may share one 5 A fuse
Isolated Power Supply: 24 VDC ± 10% @ 200 mA max Standard on 85-265 VAC powered units only.
Isolation: 4 kV input/output-to-power line.
Overvoltage Category: Installation Overvoltage Category II: Local level with smaller transient overvoltages than Installation Overvoltage Category III.
Environmental: T6 Class operating temperature range Ta = -40 to 60°C
T5 Class operating temperature range Ta = -40 to 65°C
Connections: Removable screw terminal blocks accept 12 to 22 AWG wire.
Enclosure: Explosion-proof die cast aluminum with glass window, corrosion resistant epoxy coating, color: blue. NEMA 4X, 7, & 9, IP68. Default conduit connections: Four ¾" NPT threaded conduit openings and two ¾" NPT metal conduit plugs with 12 mm hex key fitting installed. Additional conduit opening configurations may be available; verify quantity and sizes on specific device labeling during installation.
Mounting: Four slotted flanges for wall mounting or NPS 1½" to 2½" or DN 40 to 65 mm pipe mounting.
Overall Dimensions: 6.42" x 7.97" x 8.47" (W x H x D) (163 mm x 202 mm x 215 mm)
Weight: 16.0 lbs (7.26 kg)
Warranty: 3 years parts & labor

Inputs

Input Types: NO or NC switches: No external excitation required.
Open collector transistor: Open circuit voltage approx. 3.3 VDC.
Logic Levels: LOW = 0 to 0.9 VDC, HIGH = 2.4 to 28 VDC
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.
