9106 - Product version 9106-002
Application
• 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.
• The PR 4511/4501 displays the process value for each channel and can be used to define high and low limits for detection
of loop current level. If these limits are exceeded, the status relay will activate.
• In the 1-channel version the status relay can be used as a simple limit switch.
• 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 9106xxB can be used as a splitter with the following output configuration:
• When using 9106xxB 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), 9106xxB 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).
Advanced features
• The PR 4511/4501 detachable display and the green and red front LEDs indicate operation status for each channel.
• A tag number can be defined 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.
Technical characteristics
• High galvanic isolation of 2.6 kVAC.
• Fast response time <5 msec.
• High accuracy better than 0.1%.
• 2-wire transmitter supply >16 V.
