(Zone 0 / Zone 20 with a suitable Ex ia Power Supply)

The 9471-ET(G) is an Intrinsically Safe (IS) Ethernet to Serial 4 Port

Communication Module suitable for Zone 1 / Zone 21 mounting,

(Zone 0 / Zone 20 with a suitable Ex ia Power Supply).

The Module allows existing Intrinsically Safe equipment with an RS485/

RS422 or RS232/TTL port to become Ethernet Enabled via a Cat5e/6

cable connection into an IS Ethernet Network (LAN). The unit has 4

serial ports, each one supporting either RS485/RS422 or RS232/TTL

depending upon the configuration required. There are 2x RJ45 (LAN)

ports that support 10/100/1000 IS Ethernet connections - these allow

‘daisy-chaining’ of units together.

Power (12V DC) is supplied to the module either locally or using Power

over Ethernet (PoEx) from either LAN port - This requires the PoEx

output to be wired to the Supply Input terminals by the user.

Note: PoEx not available on Gigabit versions

The compact and cost effective design makes it the ideal choice for

many applications:

Petrochem - Process Monitoring, Legacy Systems...

Mining - 

Underground Communication Links, Machine Monitoring, Legacy

Systems….

Electrical connections are via cage-clamp and/or screw type plug/

socket terminals along with RJ45 type connectors for the Ethernet

LAN ports.
