1. Chemical Processing Plant Hazardous Area Monitoring
The Z787 Zener Barrier enables safe interfacing of 2-wire DC sensors, such as pressure or temperature transmitters, located in potentially explosive atmospheres (Zone 0/1/2) within chemical processing plants. It connects these field devices to control systems in the safe area without transferring ignition-capable energy.
Problem SolvedPrevents explosions in hazardous chemical environments by intrinsically limiting electrical energy, ensuring safe and compliant monitoring of critical process parameters. The 26.5V working voltage and 50mA fuse rating precisely manage energy transfer.

2. Oil & Gas Offshore Platform Signal Isolation
This Zener Barrier protects sensitive communication and sensor lines from intrinsically safe field devices, such as flow meters or level sensors, on offshore oil rigs or in refineries. It ensures that electrical faults in the safe area do not generate sparks in explosive gas mixtures present in the hazardous environment. Its DIN rail mounting simplifies integration into industrial control cabinets.
Problem SolvedSafeguards critical data acquisition and control loops in highly combustible oil and gas environments, enhancing operational safety, minimizing downtime, and ensuring regulatory compliance with its intrinsic safety design and IP20 protection for enclosed installations.

3. Pharmaceutical Manufacturing Solvent Vapor Protection
The Z787 provides a secure interface for 2-channel DC control signals to actuators or sensors within pharmaceutical cleanrooms where flammable solvents may be present. Its IP20 rating is suitable for installation within protective enclosures, while its intrinsic safety is paramount for preventing the ignition of solvent vapors during critical manufacturing processes.
Problem SolvedEnsures electrical safety in pharmaceutical production areas containing flammable materials, protecting both sensitive processes and personnel. The 2-channel capability allows for simultaneous safe control or monitoring of two independent signals, critical for complex operations.
