Intrinsic Safety Barriers - Eaton MTL 7700 Series
The MTL7700 Series of intrinsically safe passive network devices use zener diodes, resistors and fuses to safely divert excess electrical energy to ground and prevent sparking or overheating of equipment in hazardous areas.
The MTL7700 intrinsic safety device provides quick and easy installation and maintenance with removable terminals, the loop can be disconnect by simply unplugging the terminals from the side of the module. Wire entry is also angled to assist wiring within limited space enclosures.
DIN-rail mountable the MTL7700 intrinsic safety devices clamp simply and securely onto standard T-section DIN rail, simultaneously making a reliable intrinsically safe earth connection.
For applications where field device power is required for switch inputs or 2-wire transmitters, the MTL7700 barrier range provides a bussed power feed facility. When used in conjunction with the MTL7798 power feed module the user has a fully protected, electronically fused supply to many barriers with no additional wiring required.
All MTL7700 range zener barriers are based on the same simple principle. Each channel contains two stages of pulse-tested Zener or forward-connected diodes and an infallible terminating resistor. In the event of an electrical fault in the safe area, the diodes limit the voltage that can reach the hazardous area and the resistor limits the current. A fuse protects the diodes, and the two stages of voltage limitation ensure continued safety if either stage should fail. No active output current limiting circuits are employed. All models are certified ia for all zones and IIC for all explosive atmospheres (except MTL7707P+ and MTL7729P+, 'ia' 'IIB').

Eaton MTL Zener Barrier, 300mA Maximum Current, 2.7V DC Maximum Voltage - MTL7700 Series - MTL7756AC/RS
Looking for a reliable solution to prevent your equipment overheating or sparking in hazardous areas? This Eaton MTL zener barrier is an intrinsic safety solution that effectively diverts excess energy and mitigates risks to people and instruments. The unit's diodes and resistors limit the voltage and current passing to equipment when electrical faults occur. It's suitable for use with field devices that have switch inputs or 2-wire transmitters.
Features & Benefits
Removable terminals make installation and maintenance quick and simple
Angled wire entry makes it easy to wire in confined spaces
T-section DIN rail mounting capability lets you reliably secure the device and establish a safe earth connection
Operating temperature range between -20°C and +65°C for reliable use in harsh conditions
