exercised in ensuring that the power supplied by these barriers does not exceed
the maximum safety values permissible for the field device. These values are
shown on the certificate accompanying the field device and the safety values for
These barriers often transfer the analogue output from a PLC
or DCS System to the hazardous area. Products listed are part of huge range
available. Typical applications include powering I/P converters,
Positioners or Digital
Indicators in the hazardous area. All devices shown are certified: Ex II (1) GD [EEx ia] IIC
