Technical Specifications Table

Target Equipment & Application Scenarios

• Offshore Production Platforms: Protects wellhead towers and hydrocarbon processing decks from explosive gas leaks.
• Gas Turbine Enclosures: Monitors fuel lines inside turbine acoustic enclosures for rapid leak detection.
• Petrochemical Storage Vaults: Triggers localized horns and ventilation fans directly via internal relay contacts.

Self-Diagnostics & System Reliability

Continuous internal routines check optical path integrity, microprocessor state, and relay contact health.

The backlit LCD displays clear fault codes and warning indicators during sensor obstruction or low supply voltage.

Model Selection & Technical Comparison

Engineering Advice: Select the XNX-AMAI-RNIV1 when your site requires physical relay contacts for direct local alarm tripping.

Global PLC Spare HUB's Insight & Field Experience

During a gas compressor station overhaul, an engineering client required localized emergency fan tripping.

The control room DCS had limited spare digital input cards for immediate auxiliary wiring expansion.

Our team recommended deploying the Honeywell XNX-AMAI-RNIV1 with its internal SPDT relay board.

Technicians wired the relay contacts directly to the local exhaust fan starters for immediate activation.

This design eliminated additional cabinet wiring costs while fulfilling strict safety shutdown response times.

Packaging, Delivery & Warranty Terms

We test and pack every XNX-AMAI-RNIV1 transmitter securely for global dispatch.

Orders ship within 24 to 48 hours using express couriers including FedEx, UPS, and DHL.

Every unit includes standard 12-month warranty coverage against manufacturing defects.

Frequently Asked Questions (FAQ)

Q1: How do the internal relays operate on the XNX-AMAI-RNIV1 transmitter?

A1: The internal relay card provides three programmable SPDT contacts for Low Alarm, High Alarm, and Fault conditions.

Q2: Can field teams configure alarm thresholds without opening the transmitter enclosure?

A2: Yes, technicians use non-intrusive magnetic switches to navigate menus through the front glass window.

Q3: How does this unit differ from model XNX-AMAI-NHIV1 during field maintenance?

A3: The XNX-AMAI-RNIV1 includes internal relays, while model XNX-AMAI-NHIV1 adds an external local HART port.

Q4: Is an additional transmitter module required to connect Searchpoint Optima sensors?

A4: No, the "I" personality module natively processes digital inputs from Searchpoint Optima and Searchline Excel detectors.

Q5: What cable gland type fits the M25 entry ports on this enclosure?

A5: Install certified M25 x 1.5 explosion-proof cable glands to maintain ATEX/IECEx compliance and IP66 sealing.
