MTL 7758+ Field-Mounted Isolator | 4-20mA, RTD/T/C, Loop Power, IP66/68, ATEX/CSA

MTL 7758+ universal isolator specifications. Rugged field-mount, accepts 4-20mA, RTD, thermocouple, provides loop power, IP66/68, hazardous area certified.

Product Overview

The MTL 7758+ is a rugged, field-mountable universal isolator designed for installation in Zone 2/22 or Division 2 hazardous areas. It accepts a wide range of input signals (4-20mA, RTD, thermocouple) from field transmitters and sensors, provides signal conditioning and isolation, and delivers an isolated 4-20mA output. Housed in a robust, weatherproof enclosure, it is designed for direct mounting in harsh outdoor or industrial environments, enabling signal conversion and isolation at the field device location.

Technical Specifications

Key Features

• Universal Input:​ Configurable for 4-20mA, RTD, or thermocouple inputs

• High Accuracy:​ Up to ±0.05% analog signal accuracy

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

• Optical Configuration:​ Infrared optical port for wireless configuration

• Advanced Diagnostics:​ Monitors loop health and signal integrity

• Linearization:​ Built-in for RTD and thermocouple inputs

• Visual Status:​ LEDs for power, operational status, and fault indication

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

Applications

• Signal isolation for field transmitters in Zone 2/Div 2 areas

• Temperature measurement with RTD or thermocouple sensors

• Tank farms and remote pipeline monitoring

• Offshore platforms and oil & gas production sites

• Water and wastewater treatment plants

• Any remote location requiring signal conditioning and isolation

Important Notes

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

2. Input type (4-20mA, RTD, T/C) must be configured via software

3. Configuration is performed via infrared optical port, no physical connection needed

4. The 4-20mA output is active and requires an external 24V DC supply for its loop

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