The 9661-ETW is an MTL Intrinsically Safe (IS) Ethernet to Serial

4 Port Communication Module suitable for Zone 1 mounting with a

suitable Ex ib power supply, Zone 0 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

either Wi-Fi (WLAN) or a Cat5/6 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 2 RJ45 (LAN) ports that support 10/100 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 the LAN port - This requires the PoEx

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

The compact and cost effective design makes it the ideal choice

for many applications such as Petrochemical - Process Monitoring,

Legacy Systems and Mining - Underground Communication Links,

Machine Monitoring and Legacy Systems.

Electrical connections are made via cage-clamp plug/socket terminals

along with a dual RJ45 type connector for the Ethernet LAN ports.

Twin SMA Style RF connectors allow one or two antenna to be

connected as required.
