HART transparent repeater

9106B

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 9106BxB can be used as a splitter with the following output configuration:
· When using 9106BxB 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), 9106BxB 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).

The PR 4501 detachable display and the green and red front LEDs indicate operation status for each channel.
Monitoring of error events and cable breakage on input via the individual status relay and/or a collective electronic signal via the power rail.

The devices can be mounted vertically or horizontally without distance between neighboring units.
