The Series 9740 Ethernet-APL field switches are intended for the connection of intrinsically safe "2-WISE" field devices to higher-level 4-wire Ethernet networks, and supply the devices with intrinsically safe power. The field switches can be installed in Zone 1. The integrated diagnostics functions of the Ethernet-APL field switches make commissioning or troubleshooting far easier and faster.
- Operation of 16 Ethernet-APL or PROFIBUS PA field devices (PA proxy, only for 9740/12-16-40)
- All spurs intrinsically safe "ia" (2-WISE) with port profile A or A+B (only for 9740/12-16-00)
- Operation with 100BASE-TX (Zones 1, 2) and optionally 100BASE-FX (Zone 2)
- Redundant auxiliary power supply and extensive integrated diagnostics
- Installation in Zone 1
