* SIL3 is the maximum achievable for a single channel. Selected CPU, input and output voting
configurations may increase or decrease the actual SIL achieved. Refer to the Safety Manual

T9851/2 Termination Assemblies for Digital Outputs
There are two termination assemblies for use with digital output modules - for simplex
and dual applications. A T9851 termination assembly (pictured) is for a simplex
application and provides terminations for 8 digital outputs. It supports one T9451
digital output module. A T9852 termination assembly is a dual assembly, again for 8
outputs, which supports two T9451 digital output modules.
The termination assembly routes the output channels for final elements from the
digital output module to terminal blocks for field connections. The terminal blocks also
accept two 24V dc power sources for field power. The termination assembly
incorporates two replaceable 10A fuses, one for each power source. These fuses can
protect the output module against some field faults.
