ATEX ECS-R Monitoring System

The system monitors that connection to earth is obtained with a resistance lower than 10Ω, according to the ATEX Directive 2014/34/EU.

The device can be equipped with two Ex i outputs for remote LEDs installed directly on the clamp (consensus green LED and non consensus red LED).

General Features:

– Compact and rugged Ex-d enclosure suitable for ATEX Zone 1/21 installation
– Equipped with high efficiency redundant green and red LEDs for connection monitoring
