Invensys TRICONEX 3706A 3708E THERMOCOUPLE ANALOG INPUT MODULE
3706A 3708E THERMOCOUPLE ANALOG INPUT MODULE Function
A thermocouple input (TC) module includes three independent input channels. Each input channel receives variable voltage signals from each point, performs thermocouple linearization and cold-junction compensation, and converts the result to degrees Celsius or Fahrenheit. Each channel then transmits 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 thermocouple type, selected from J, K and T for standard thermocouple input modules and from J, K, T and E for Failure of any diagnostic on any channel activates the Fault indicator, which in turn activates the chassis alarm signal. The module Fault indicator merely reports a channel fault, not a module failure. The module continues to operate properly with as many as two faulty channels. The thermocouple input module supports hot-spare capability which allows online replacement of a faulty module.The thermocouple input module requires 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. isolated thermocouple input modules. The isolated module allows users to select upscale or downscale burnout detection with the TriStation software. For non-isolated modules, upscale or downscale burnout detection depends on the field termination selected
