  • Page 8: System Design For Hazardous Area

    In addition to the EC-Type Examination Certificate, ITS issued two System Certificates for the BA454D batch controller. One defines how the BA454D may be used with Zener barriers and the other with galvanic isolators. Both are divided into two sections to cover input signal sources in the hazardous and the safe area.

    4.3.2 Inputs When the batch controller is powered from a galvanic isolator, the pulse and analogue inputs remain the same as described in sections 4.2.2 and 4.2.3. Only when the input transducer or source is in the safe area, as shown in Fig 7, are galvanic isolators required in the input circuit.
