Triconex 3708E Thermocouple Analogue Input

Thermocouple Input Modules
Thermocouple Input (TC) modules
include three independent input chan-
nels. Each input channel receives vari-
able voltage signals from each point,
performs thermocouple linearization
and cold-junction compensation, and
converts the result to degrees Celsius or
Fahrenheit. Each channel then trans-
mits 16-bit signed integers representing
0.125 degrees per count to the three
Main Processors on demand. In TMR
mode, a value is then selected using a
mid-value selection algorithm to ensure
correct data for every scan.
Each Thermocouple Input Module is
programmable to support one thermo-
couple type, selected from J, K and T
for standard Thermocouple Input
Modules and from J, K, T and E for isolated Thermocouple Input Modules.
The isolated module allows users to
select upscale or downscale burnout
detection with TriStation 1131. For
non-isolated modules, upscale or
downscale burnout detection depends
on the field termination selected.
Triplicated temperature transducers
residing on the field termination panel
support cold-junction compensation.
Each channel of a Thermocouple Input
Module performs auto-calibration
using internal precision voltage refer-
ences. On the isolated module, a
faulting cold-junction transducer is
annunciated by a cold-junction indi-
cator on the front panel.
Each module performs complete
ongoing diagnostics on each channel.
Failure of any diagnostic on any channel activates the Fault indicator,
which in turn activates the chassis
alarm signal. The module Fault indi-
cator merely reports a channel fault, not
a module failure. The module continues
to operate properly with as many as two
faulty channels.
Thermocouple Input Modules support
hot-spare capability, which allows
online replacement of a faulty module.
Thermocouple Input Modules require a
separate external termination panel
(ETP) with a cable interface to the
Tricon backplane.
Each module is mechanically keyed to
prevent improper installation in a
configured chassis.
