TRICONEX 3501TN2 8-Point Supervised Digital

Output Modules

Designed for the most critical applica

tions, supervised digital output (SDO)

modules meet the needs of systems

TRICONEX 3501TN2 whose outputs remain in a single state

for extended periods of time (in some

applications, for years). An SDO

module receives output signals from the

main processors on each of three chan

nels. Each set of three signals is then

voted upon by a fully fault-tolerant

quadruplicated output switch whose

elements are mechanical power relays,

so that one voted output signal is passed

to the field termination.

Each SDO module has voltage and

current loopback circuitry coupled with

  • A shorted load in the de-energized


TRICONEX 3501TN2 Failure to detect field voltage on any

output point energizes the power alarm

indicator. Failure to detect the presence

of a load energizes the load alarm indi

cator. When an optional secondary

power supply is used, shorted loads in

the OFF state can be detected. (This

feature is not provided on model

3611E, an AC module.)

All SDO modules support hot-spare

capability and require a separate

external termination panel (ETP) with a

cable interface to the Tricon backplane.

sophisticated online diagnostics that

verify the operation of each output

switch, the field circuit and the pres

ence of a load. This design provides

complete fault coverage without the

need to influence the output signal.

The modules are called “supervised”

because fault coverage is extended to

include potential field problems. In

other words, the field circuit is super

vised by the SDO module so that the

following field faults can be detected:

  • Loss of power or blown fuse
  • Open or missing load
  • A field short resulting in the load

being energized in error
