Eaton Zener Barrier, ATEX, 1 Channel, 28V DC Supply, 93mA Max Safety Current MTL7706+/RS

Eaton MTL7706+/RS Zener Barrier is a single channel intrinsically safe barrier designed for industrial and hazardous area applications requiring ATEX certification. It operates on a 28V DC supply voltage and supports a maximum safety current of 93mA, ensuring energy efficient field device protection.

In hazardous environments, the MTL7706+/RS safely regulates electrical energy supply by employing Zener diodes, an output resistor, and fuse components that redirect excess voltage to ground and prevent overloads. This intrinsic safety barrier features built-in overvoltage protection to prevent damage from wiring faults and allows usage with unregulated power sources.

The device is engineered for ease of installation with angled wire entries and screw terminals that are colour coded to simplify wiring and maintenance. Its DIN rail mounting compatibility allows secure, tool-free attachment to standard T-section DIN rails common in industrial electrical panels.

With a wide operating temperature range of -20°C to 65°C, this Zener barrier withstands demanding environmental conditions commonly found in industrial, manufacturing, chemical, and process control applications. The compact dimensions (105 x 90 x 12.6 mm) facilitate easy integration into control systems.

Eaton's MTL 7700 series Zener barriers provide quick installation and reliable protection for intrinsically safe circuits. Their rugged construction ensures safe operation, minimizing risks of sparking or overheating in hazardous atmospheres.
