With electronic monitoring system

ECS-R series electronic equipment provides earth connection of process equipment (road tankers, drums, IBCs, etc..) with real-time ground connection monitoring. The system monitors that connection to earth is obtained with a resistance lower than 10Ω.

General Features

Compact and rugged Ex-d enclosure

Equipped with high efficiency redundant green
and red LEDs for connection monitoring

1x N.O. contact for safety application up to SIL 2 (ECS-RF only)

N. 1 SPST N.O. contact for clamp state remote monitoring

2x Ex i outputs for remote clamp on-board LEDs driving


Meets the requirements of ATEX Directive 2014/34/UE
and related harmonized standards for Zone 1/21.
