Crouse-Hinds series MTL 9661-ETW is an intrinsically safe (IS) ethernet to serial 4 Port communication module suitable for Zone 1 mounting with a suitable Ex ib power supply, and suitable for Zone 0 with a suitable Ex ia power supply.
The MTL 9661-ETW 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 Ôdaisy-chainingÕ of units together.
The compact and cost effective design makes it an ideal choice for many industrial applications such Process Monitoring & Legacy Systems (Petrochemical), as well as Underground Communication Links, Machine Monitoring and Legacy Systems (Mining).
