PR electronics 9106B HART transparent repeater. 9106B is a 1- or 2-channel isolated 1:1 repeater barrier for intrinsic safety applications. The device supplies 2-wire SMART transmitters and can also be used for 2-wire SMART current sources. HART & BRAIN protocols are supported and are transferred bi-directionally. 9106B can be mounted in the safe area or in zone 2 / Cl. 1, div. 2 and receive signals from zone 0, 1, 2 and zone 20, 21, 22 including mining / Class I/II/III, Div. 1, Gr. A-G. For duplication/migration purposes, the outputs can be sent to two different DCS/PLC/HMI or any monitoring system. In safety applications (SIL loops), the 9106BxBx can be used as a splitter with the following output configuration:
• When using 9106BxBx in a SIL2 safety function, channel 1 is used for the safety loop. Channel 2 can be used for any non-safety device.
• For higher safety purposes (SIL 3), 9106BxBx can be used as a splitter for SIL 3 loops. Channel 1 and 2 are then connected to the same safety PLC, where channel 2 is used as a redundant diagnostic channel (for more information, consult the FMEDA Report and the Safety Manual).
