Description

EARTHING CLAMP 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. • 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 • N.1 x N.O. contact for safety application up to SIL 2 (ECS-RF only) • N.1 x SPST N.O. contact for clamp state remote monitoring • N.2 x Ex i outputs for remote clamp on-board LEDs driving Meets the requirements of ATEX Directive 2014/34/UE and related harmonized standards for ATEX Zone 1/21 installation. Technical Characteristics: ATEX Marking II 2(1)G Ex d[ia Ga] IIC T6 Gb -20 °C ≤ Tamb ≤ +40 °C for gases, vapors and mists II 2(1)D Ex tb[ia Da] IIIC T 85°C Db -20 °C ≤ Tamb ≤ +40 °C for dusts Clamp input Ex i Uo=7.2 V, Io=345 mA, Po=621 mW, Co(IIC)=13,5 μF, Lo(IIC)=149 μH LEDs outputs Ex i Uo=7.2 V, Io=23 mA, Po=42 mW, Co(IIC)=13,5 μF, Lo(IIC)=34 mH Monitoring contact 1x SPDT max 230Vac/1A 24Vdc/1A (resistive/inductive load) Interlock contact 1x N.O. max 230Vac/1A 24Vdc/1A (resistive/inductive load) up to SIL2 acc. IEC 61508 (ECS-RF only) Power supply 230 Vac + 5% Max current 150 mA Resistance threshold 10 Ω Dimensions 195 x 195 x 148 mm (W x H x D)
