Description
The Mercury Switch (PR0018) is a device that allows up to 10 RDM Mercury controllers to be connected to an IP network, without the
need for individual IP Futura modules. There are 10 RS232 connections for linking to 10 Mercury controllers. There are 3 standard
Ethernet Switch (10/100baseT) connections for other network devices. The Ethernet ports are self configuring for uplinks and standard
10/100 Base T device connections.
As well as the Switch function there is the option for Island EEV control. This control can be achieved by using a transducer connected to
the Mercury Switch 4-20mA input or from a remote Suction pressure reading sent across an IP network from a Mercury Plant Pack
controller. Island trim heater control can also be achieved through the display port using a humidity temperature display (PR0445). To
utilise either of these features then the PR0018-PHI build option would be required.
