SAFT 110 System Integration

The SAFT 110 POW integrates seamlessly within ABB's SAFT 110 safety application field transmitter ecosystem, providing intrinsically safe power to transmitter electronics while maintaining galvanic isolation from hazardous area field wiring. The module mounts in safe area control panels with DIN rail installation, connecting to SAFT 110 transmitters via shielded twisted-pair cables rated for intrinsic safety applications. Integration with safety PLCs and DCS systems enables comprehensive safety loop monitoring and diagnostics.

Engineering Design Excellence

• Global Hazardous Area Certification: ATEX, IECEx, FM, and CSA approvals enable worldwide deployment in Zone 0/1 (IEC) and Division 1 (NEC) classified locations without regional re-certification
• Extended Temperature Range: -40°C to +70°C operation accommodates outdoor installations, unheated enclosures, and extreme climate conditions without derating or environmental protection
• Conformal Coating Protection: Circuit board coating provides resistance to moisture, salt spray, corrosive gases, and chemical vapors in harsh offshore and chemical processing environments
• Hot-Swappable Design: Redundant configurations allow module replacement during system operation without interrupting safety transmitter power or losing measurement continuity
• Compact Form Factor: Space-efficient DIN rail mounting minimizes panel real estate requirements in crowded marshalling cabinets and junction boxes
• Long Service Life: Industrial-grade components and conservative thermal design ensure >15-year operational life matching typical safety system lifecycles with minimal maintenance

Installation & Commissioning

The module installs on standard 35mm DIN rail with spring-loaded retention clips for tool-free mounting. Input power connects via screw terminals accepting 12-22 AWG wire, while intrinsically safe output connections utilize removable terminal blocks with clear labeling for hazardous area wiring. Installation involves verifying input voltage compatibility, connecting output to SAFT 110 transmitter, and confirming proper grounding for isolation integrity. Commissioning includes input voltage verification, output voltage measurement, and functional testing of diagnostic indicators—typically completed in 15-20 minutes per module.
