MTL 9122-IS-PS FISCO Fieldbus Power Supply

Product Description

The MTL 9122-IS-PS is a simplex FISCO fieldbus power supply and repeater isolator with screw terminals, designed for Foundation Fieldbus IIB hazardous gas group applications. It transfers fieldbus signals from safe area or Zone 2 to intrinsically safe fieldbus segments for Zone 1 instruments. Certified to ATEX, IECEx and CCC Ex standards, it supports live maintenance on the field side without gas clearance, widely used in process safety automation systems.

Product Functions

• Provides intrinsically safe fieldbus power and signal isolation, max output current up to 256mA
• Acts as fieldbus repeater and galvanic isolator, 250V isolation between host and field side
• Switch-selectable host termination and host side power supply function
• Fixed termination on the intrinsically safe field side
• LED status indicators for fault diagnosis and segment monitoring
• Complies with IEC 60079-27 FISCO intrinsic safety specification

Application Scenarios

• Oil & gas, petrochemical, chemical process hazardous area control
• Foundation Fieldbus segments in Zone 1 / Zone 2 explosive environments (IIB gas group)
• Refineries, pipelines, pharmaceutical plants and mining process automation
• Process safety control systems requiring live hot work on field instruments
