Specifically designed for mounting in Zone 1 or Division 1 areas within suitable enclosures, this 5-port module facilitates the interconnection of the MTL 9460-ET networking range. It is indispensable for critical infrastructure in oil and gas refineries, chemical processing plants, and underground mining operations where explosive atmospheres are present. By utilizing a low-latency 'store and forward' mechanism and providing broadcast storm protection, the MTL 9466-ET ensures deterministic communication and high network availability.
