Eaton Zener Barrier, 28V Supply Voltage, 300Ω Safety Current Resistance - CROUSE-HINDS Series - MTL7728+/RS

Keep your equipment safe and sound with this ISB-type Zener barrier from Eaton. It uses diodes, fuses and resistors to divert excess energy to earth, creating an intrinsically safe environment that prevents system damage caused by sparking or overheating. Link it up to a bussed power feed or solid state relay switch for additional protection and peace of mind. Removable terminals make maintenance and repair of this unit a cinch.

Features & Benefits

• Angled wire entry for ease of connection in tight spaces

• DIN-rail mounting for hassle-free installation

• Wide operating temperature range between -20°C and +65°C, so it's suitable for use industrial use

How does a Zener barrier work?

A Zener barrier works in two stages. If there's an electrical fault, the diodes restrict the voltage that would otherwise reach the hazardous area, while the resistor curbs the current. This design ensures a seamless safety net even if one of the stages malfunctions.

What does ISB mean?

ISB stands for Intrinsic Safety Barrier. ISB devices like this one limit the energy that can be brought from a safe source to a hazardous area, preventing explosive results.
