Eaton MTL5511 Intrinsically Safe Analog Input Isolator
The Eaton MTL5511 is an intrinsically safe analog input isolator designed as associated apparatus for hazardous-area applications. It enables the safe transfer of 4–20 mA signals from field-mounted transmitters installed in Zone 0, Zone 1, or Class I Division 1 hazardous locations to safe-area control systems, while maintaining galvanic isolation and intrinsic safety integrity.
Part of the trusted Eaton MTL5000 Series, the MTL5511 provides high signal accuracy, excellent noise immunity, and reliable galvanic isolation between hazardous and safe areas. Its DIN-rail mounted, loop-powered design simplifies installation in control panels and marshalling cabinets, making it ideal for demanding industrial environments where safety, performance, and long-term reliability are critical.
