The 946X and the 947X product range provides cost-effective Intrinsically Safe (IS) Ethernet equipment and also the new Gigabit range launched in 2021 that can be installed and maintained easily in hazardous areas.
The intrinsically safe hazardous area certification permits the components to be mounted in a Zone 1 hazardous area with connectivity into Zone 0 and the associated apparatus certification of the 9468-ET IS Ethernet isolator and 9492-PS-PLUS power supply allow this equipment to be mounted in a Zone 1 hazardous area and connected to intrinsically safe equipment in a Zone 0 hazardous area.
In Process Automation it is also preferable to use a single cable to provide both power and communications to the end device. The 9470-ET/ETG range can deliver Intrinsically Safe Power over Ethernet (PoEx™) with a single Cat 5e or Cat 6 cable, allowing live connection and disconnection of the end device in Zone 0 and 1 hazardous areas.
Also the new Gigabit range is suitable for bandwidth intensive applications and the 9476-ETG switch comes with advanced managed features.
Intrinsically Safe Managed Switch
Intrinsically Safe Ethernet Wireless access point/bridge
Intrinsically Safe Serial to Ethernet Gateway
In addition, the module’s front panel screw terminals (T6 – T15) provide two RS485/RS422, 2- or 4- wire ports, giving a total of four serial ports. All ports can operate at speeds up to 115K baud.
IS Ethernet Isolator
The 9468-ET 10/100Mbps, Isolating Ethernet Barrier allows the interconnection of a Zone 2 or un-certified safe area device to the intrinsically safe 9400-ET series of Ethernet networking products, operating in the hazardous area. The isolating barrier provides a compact alternative solution to fibre optic cable and media converters and for when it is desirable to use Cat5e cables in preference to fibre.
9476-ETG IS Gigabit Managed Switch
The 6x RJ45 (LAN) ports support 10/100/1000 IS Ethernet connections.
Available in 6 Port Gigabit and also Mixed Gigabit and 10/100 + PoEx
versions to suit various applications.
over Ethernet (PoEx) for the connected devices where required.
Module suitable for Zone 1 / Zone 21 mounting, (Zone 0 / Zone 20 with a suitable Ex ia Power Supply).
The use of 1310nm optics (instead of 850nm) allows a longer fibre-optic
link length, typically 10Km at (Gigabit) 1000Mbps using Single Mode
fibre or 500m when using multi-mode fibre.
There are 2x RJ45 (LAN) ports that support 10/100/1000 IS Ethernet
connections – these can allow ‘daisy-chaining’ of units together.
9479-ETG-CSL IS Gigabit Ethernet WLAN AP / Bridge

It may be configured as either an AP or Client/Bridge. Also supporting either 2.4GHz or 5GHz operation further extends its range of
There are 2x RJ45 (LAN) ports that support 10/100/1000 IS Ethernet connections – these can allow ‘daisy-chaining’ of units together.
9471-ETG IS Gigabit Ethernet 4 Port Serial Gateway
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.
