Eaton MTL MTL7741 Dual Channel 4-20mA Current Loop Zener Intrinsic Safety Barrier Ex ia ATEX DIN Rail Hazardous Area

Product Overview

The MTL7741 is a single-channel Zener barrier from Eaton's Crouse-Hinds series MTL7700 range, specifically designed to interface switch or proximity detector inputs with a changeover relay output in hazardous area installations.

This intrinsically safe passive device safely transfers electrical signals between safe and hazardous areas while limiting voltage and current to prevent ignition of flammable atmospheres. With a 24V DC supply and 26mA switching current, the MTL7741 is the ideal solution for digital input applications requiring relay output isolation in Zone 0, 1, and 2 hazardous locations (gas groups IIC, IIB, IIA).

Key Features & Benefits

Built-in Overvoltage Protection: Integrated overvoltage protection safeguards the circuit from voltage spikes and transients
Single-Channel with Relay Output: One intrinsically safe channel with a changeover relay output (C/O relay) – provides isolated switching for digital input applications
24V DC Operation: Rated supply voltage of 22.9-30 V DC (nominal 24V DC) – compatible with standard industrial control systems
26mA Switching Current: Adequate current handling for proximity sensors and switch inputs
Proximity Sensor or Switch Input: Specifically designed for interfacing with proximity detectors (NAMUR) and mechanical switch inputs
Removable Terminals: Unique removable terminal blocks for easy cabling, maintenance, and loop disconnect by simply unplugging terminals from the side of the module
Bussed Power Capability: Integrated bussed power feed facility reduces cabling requirements when used with the MTL7798 power feed module
Angled Wire Entry: Wire entry is angled to assist wiring within limited space enclosures
Ultra-Slim DIN Rail Mounting: Compact 12.6 mm width for standard 35 mm T-section DIN rail
Dual-Stage Protection: Contains two stages of pulse-tested Zener diodes and an 'infallible' terminating resistor
Direct Replacement for MTL700 Series: Compatible terminal numbering and safety descriptions allow direct replacement of older MTL700 series barriers
Global Approvals: ATEX, IECEx, UL, CSA certifications for international installation flexibility
