The MSA Safety A-ULTX-PCB-E-3-3-S-0-0 is a factory-specified replacement main printed circuit board (PCB) transmitter electronics assembly configured for the industry-leading Ultima X series of fixed gas monitors (such as the Ultima XE and XIR). This premium version is engineered as a 3-wire system that generates a standard 4-20mA analog output alongside integrated local LED and alarm relay boards. Programmed with the Spanish language local menu interface (“S” software variant) and supporting an active local LCD display layout, this core processing module serves as the primary intelligence of the instrument. It converts raw smart-sensor feedback into highly reliable plant-safety data without requiring an expensive replacement of the explosion-proof metal enclosure.
