HONEYWELL
ASSY: 51306177-100
ANALOG INPUT MODULE
REV: B
The Honeywell Analog Input Module (assembly 51306177-100, Rev B) is a signal processing component designed to receive and condition analogue inputs from gas detection sensors. As a core element within a marine gas detection system, this module converts field-level sensor signals into data that the control panel or central processing unit can interpret, enabling real-time gas concentration monitoring, threshold evaluation, and alarm activation. Reliable signal acquisition at the module level is fundamental to the integrity of the overall detection system and the safety of personnel and vessel operations.
Key Features
✓ Processes analogue input signals from gas detection sensors, supporting accurate concentration readings and system response — exact input ranges subject to confirmation against system configuration.
✓ Manufactured by Honeywell to industrial-grade standards; specific electrical ratings, certifications, and approvals are not stated in available data and should be verified against the original system documentation.
✓ Compatible with Honeywell gas detection control architectures typical of this assembly series; compatibility with specific panels or controllers should be confirmed using system model, version, and drawing references.
✓ Designed for installation within a control cabinet or dedicated enclosure as part of a structured gas detection system; mounting and environmental requirements depend on the installation context and should be confirmed prior to fitment.
✓ Replacement or retrofit of this module should be carried out by qualified personnel with reference to the original system documentation, ensuring calibration and signal mapping are validated after installation.
Marine Applications
✓ Fixed gas detection systems aboard LNG carriers, LPG tankers, and chemical tankers where continuous analogue sensor monitoring is required in cargo and machinery spaces.
✓ Engine room and pump room gas detection networks on tankers and offshore support vessels requiring reliable signal input processing at the control system level.
✓ Offshore platforms and FPSOs where Honeywell gas detection infrastructure is integrated into safety and shutdown systems.
✓ Passenger vessels and ro-ro ferries utilising centralised gas detection panels that rely on modular analogue input cards for multi-zone sensor management.
✓ Naval auxiliaries and industrial marine vessels where Honeywell detection systems require component-level maintenance or module replacement to restore system functionality.
Why Marine Engineers Choose
Honeywell’s gas detection modules are recognised for their integration within structured safety architectures. The 51306177-100 Rev B offers a direct replacement path for vessels already operating Honeywell systems, minimising reconfiguration effort and supporting system continuity during maintenance or repair cycles.
Ideal For
Tankers, LNG & LPG carriers, chemical tankers, offshore platforms, FPSOs, passenger vessels, ro-ro ferries, and any vessel type operating Honeywell gas detection systems requiring analogue input module servicing or replacement.
Technical Support & Compliance
Technical assistance is available to support troubleshooting, commissioning verification, retrofit assessment, and system integration queries related to this module. Guidance on compatibility with existing Honeywell gas detection panels and controllers can be provided subject to confirmation. To confirm suitability, buyers are encouraged to share nameplate photographs, the full assembly and revision details, relevant system drawings or wiring diagrams, the panel or controller model and software version, and vessel name or IMO number where applicable. All compatibility and compliance assessments are subject to confirmation based on the information provided.
