ED700A


The latest ED700A system provides, in one enclosure, all necessary facilities for Gas and Level Detection. Fail safe operation. Gas and Level modules continue to function after major system failure. Loop communication or microprocessor failure still allow any ED Gas detector to provide alarm indication. Approvals - American Bureau of Shipping BASEEFA EEx ia IIC T6 or EEx d IIC T6 The ED700A panel can accommodate up to eight loop modules in any combination of ED722 or ED726 Gas and/or Level Detection giving a total of 1008 addressable devices per system.

Completely isolated loops means zero cross talk and increased immunity to radio frequency interference whilst maintaining continued operation with multiple earth faults. Additionally the very long cable run, due to the very low loop driver impedance, allows economy besides reaching far off detector heads without additional control units.
