3 × T9110 Processor Module, T9100 Processor Base Unit,

O/P A

2 × T9451 Digital Output Module, 24V dc, 8 Channel +

9852 Digital Output TA, 24V dc 8 Channel, Dual

Note: All configurations that use dual or triplicate processor modules are suitable for

SIL3 architectures with de-energize to trip outputs. Dual outputs are also required for

SIL3 energize to action outputs.

Safety-related and can be used for safety-critical

applications in SIL2 with 1 module fitted and SIL3

applications with 2 or 3 modules fitted.

Note: For High Demand applications you must use

a minimum of two processors.

Within a specified safety accuracy limit of 1.0V dc.

De-energized to action (normally energized): SIL3

with 1, 2 or 3 modules fitted.

Energize to action (normally de-energized): with 1, 2

or 3 modules fitted

Note: when the integrity level is at 1oo1D then the

faulty module must be replaced to restore the

integrity level back to 1oo2D.

Within the manufactures specified safety accuracy

limits of 200µA. The safety state of the analogue

input has to be set to a safe value which is a

calculated value based on a count value of 0mA.

SIL3 with 1, 2 or 3 modules fitted.

Note: when the integrity level is at 1oo1D then the

faulty module must be replaced within the MTTR

assumed for the PFD calculations to restore the

integrity level back to 1oo2D.
