in protection type intrinsic safety Ex ia IIC
For connection of an OPTIBAR * 5060 with integrated
electronics S or T for differential pressure measurement.
The rules for interconnecting intrinsically safe circuits
between OPTIBAR * 5060 VGK5/6/D*A/W C/U/0/H/T and
OPTIBAR * 5060 with electronics S or T are observed when the
overall inductance and overall capacity of the connecting
cable between
