AM2000EX Isolated Safety Barrier

About AM2000EX Isolated Safety Barrier

HollySys AM2000EX isolated safety barriers is used to connect intrinsically safe equipment in hazardous areas. It consists of plug-in modules and a backplane, with each module containing either 1 analog or 2 digital isolated channels. Each module has 2 connectors for plugging into the backplane-one for the intrinsically safe circuit and the other for the non-intrinsically safe circuit. The backplane is housed in a plastic enclosure, which can be mounted on a DIN rail. The backplane provides power and hazardous area wiring terminals, as well as connectors for the non-hazardous area. Each backplane can accommodate up to 8 plug-in AM2000EX modules.

Product Features

Modular & Scalable Design

Plug-in modules with 1 analog or 2 digital isolated channels per module
Each backplane supports up to 8 modules, enabling flexible system expansion
Safe & Reliable Isolation

Clear separation of intrinsically safe (hazardous area) and non-intrinsically safe (control side) circuits via dedicated connectors
Ensures compliance with explosion-proof (Ex) standards for hazardous environments
Easy Installation & DIN Rail Mounting

Compact plastic enclosure with DIN rail mounting for quick integration into control panels
Backplane provides pre-wired terminals for power and hazardous/non-hazardous area connections
Versatile Signal Support

Accommodates both analog (e.g., 4-20mA) and digital signals in a single system
Ideal for diverse industrial applications (oil & gas, chemical, mining)
