TRICONEX 3502E Dual Digital Output Module

The dual digital output (DDO) modules

receive output signals from the main

processors along a single parallel or

TRICONEX 3502E series path, and applies a 2-out-of-3

voting process individually to each

switch. The switches produce one

output signal which is then passed to

the field termination. While the quadru

plicated output circuitry on TMR

modules provides multiple redundancy

for all critical signal paths, dual

circuitry provides just enough redun

dancy to ensure safe operation. The

dual module is optimized for those

safety-critical control programs where

TRICONEX 3502E low cost is more important than

maximum availability.

The dual digital output modules have a

voltage-loopback circuit which verifies

the operation of each output switch

independently of the presence of a load

TRICONEX 3502E and determines whether latent faults

exist. Failure of the detected field

voltage to match the commanded state

of the output point activates the

LOAD/FUSE alarm indicator.

In addition, ongoing diagnostics are

performed on each channel and circuit

of a dual digital output module. Failure

of any diagnostic on any channel acti

vates the Fault indicator, which in turn

activates the chassis alarm signal. A

dual module operates properly in the

presence of most single faults and may

operate properly with some kinds of

multiple faults, but stuck-OFF faults are

an exception. If one of the output

switches has a stuck-OFF fault, the

output goes to the OFF state and a

glitch may occur during switch-over to

a hot-spare module.

The dual digital output modules

support hot-spare capability which

allows online replacement of a faulty

module. Each module is mechanically

keyed to prevent improper installation

in a configured chassis.

The dual digital output modules require

a separate external termination panel

(ETP) with a cable interface to the

Tricon backplane. Digital outputs are

designed to source the current to field

devices, so field power must be wired to

each output point on the field termina

tion.
