Design features

Terminators are clearly marked with a large ‘T’ making them easy to identify

in the field Provides some differential and common-mode (cable shield) over

voltage protection

The ground connection on the filedbus terminators are used to shunt any surge

currents that may get on the cable shield to a local ground in the junction box.

Although the normal practice is to ground the cable shield in the control room,

this additional ground connection will not cause ground loops.

In the event of an overvoltage on the cable shield, a gas discharge tube fires

and shunts this unwanted current to ground
