MTL 7796- HART Isolator | Loop-Powered, 4-20mA+HART, IP66/68, ATEX/CSA

MTL 7796- HART Isolator | Loop-Powered, 4-20mA+HART, IP66/68, ATEX/CSA

MTL 7796- HART isolator specifications. Loop-powered, 4-20mA+HART, galvanic isolation, IP66/68, hazardous area, no external power required.

Product Overview

The MTL 7796- is a rugged, field-mountable, loop-powered HART isolator designed for installation in Zone 2/22 or Division 2 hazardous areas. It operates entirely from the 4-20mA control loop power, requiring no separate power supply. It provides galvanic isolation for 2-wire HART transmitters, accepts the 4-20mA signal with HART digital communication, and delivers an isolated 4-20mA+HART output to the safe area. Housed in a robust, weatherproof enclosure, it is ideal for remote locations where external power is unavailable. The hyphen suffix "-" denotes a standard variant within the 7796 product family.

Technical Specifications

Key Features

• Loop-Powered Operation:​ Requires no external power supply; powered from the 4-20mA loop

• Integrated Loop Power:​ Supplies 24V DC to power the connected 2-wire HART transmitter

• Rugged Field-Mount Design:​ IP66/IP68 rated enclosure for harsh environments

• HART Protocol Support:​ Full bidirectional HART communication

• Galvanic Isolation:​ 500V isolation between field and safe areas

• Wide Temperature Range:​ Operates from -40°C to +70°C

• Optical Configuration:​ Infrared optical port for wireless configuration

• Simplified Installation:​ No local power wiring required

• Weatherproof:​ Suitable for outdoor, wet, and dusty locations

• Cost-Effective:​ Eliminates cost and complexity of running separate power cables

Applications

• Remote HART transmitter installations where AC/DC power is unavailable

• Tank farms and pipeline monitoring

• Offshore platforms and wellhead monitoring

• Solar-powered or battery-operated remote sites

• Water and wastewater treatment plants

• Adding isolation to existing loops without modifying power infrastructure

Important Notes

1. Certified for Zone 2/Div 2; for Zone 1/Div 1, an IS barrier is required upstream

2. Derives operating power from the safe-side 4-20mA loop supply (12-45V DC)

3. Provides loop power to the field transmitter

4. Configuration is performed via infrared optical port

5. Ensure proper sealing of cable glands for maintained IP rating
