The Ex-Isolating Barrier TV228 separates intrinsically safe and non-intrinsically safe circuits. It supplies galvanically isolated Smart (HART) or conventional positioners. Connection to hand terminal or to personal computer can be made at every location in the signal loop. The bidirectional communication between a DCS, a handheld terminal or a PC is possible.
Bidirectional communication with smart positioners
Full support of HART protocol
Intrinsically safe FM and ATEX [EEx ia] in IIC
Sockets for hand terminal or PC on the front
In industries with Intrinsically Safe protection type and valve positioners
Cabinet mounting (rail or nest mounted)
