3. Purpose of the product
HART transparent, galvanic isolation and repetition of passive and active 4...20
mA current signals from hazardous area to non-classified area.
The module can be mounted in non-classified area or in zone 2 / Div. 2 and
receive current signals from zone 0, 1, 2, 20, 21, 22 and mines or Class I/II/III,
Div. 1, Group. A-G.
Error events, including cable breakage, are monitored and signalled via the
individual status relay and/or a collective electronic signal via the power rail.
The display and programming module 4501 can be used to show the actual
process values, and alter the set point for high and low limit.
The 9106 has been designed, developed and certified for use in SIL applications
according to the requirements of IEC 61508

4.3
analogue output
The connected safety PLC shall be able to detect and handle the fault
indications from the analogue output of the 9106 Repeater by having a
NAMUR NE43-compliant input circuit.
4.4. failure rates
The basic failure rates from the Siemens standard SN 29500 are used
as the failure rate database.
Failure rates are constant, wear-out mechanisms are not included.
External power supply failure rates are not included.
