The MSA Safety A-ULTX-PCB-E-4-1-0-0-0 is a factory-specified replacement main printed circuit board (PCB) assembly designed for the industry-leading Ultima X series of fixed gas detectors (including Ultima XE and Ultima XIR models). Configured specifically as a four-wire unit with a standard 4-20mA analog output, this core electronics module provides critical signal processing, sensor-channel management, and advanced detection logic. The 4-wire design provides isolated power and signal loops for enhanced noise immunity and flexible power wiring options in complex industrial grids. It combines vital diagnostic hardware with display interface capabilities into a single field-replaceable component. Engineered to restore complete monitoring functionality without requiring full transmitter enclosure replacement, it ensures continuous, high-reliability life-safety telemetry in demanding environments.

Key Features
- Serves as the central computing and interface assembly, handling raw gas concentration signals and converting them into calibrated telemetry data.
- Utilizes a 4-wire system configuration to separate the power supply lines from the 4-20mA signal loops, eliminating ground loops and reducing electrical noise in long-distance runs.
- Integrates seamlessly with MSA’s smart sensor technology, enabling plug-and-play recognition, historical log tracking, and auto-configuration upon connection.
- Features a modular, direct-fit design that allows certified plant technicians to swap out damaged circuitry efficiently, minimizing system down-time.
- Built using industrial-grade electronic components to withstand high ambient vibration, extreme temperatures, and heavy RFI/EMI plant interference.
Applications
- Field servicing, repair, and loop-testing of failed electronics inside certified 4-wire MSA Ultima XE and XIR gas monitors.
- Maintaining critical safety infrastructure in oil & gas facilities, chemical plants, and heavy manufacturing refineries where isolated, high-reliability toxic or combustible gas telemetry is mandatory.
- Stocked as an essential critical spare module for facility instrumentation groups managing fixed-gas detector grids across classified industrial zones.
