ICS Triplex T9432

ICS Triplex  T9432  Analogue Input Module, 8/16 Channel

The T9431/2 analogue input module monitors eight (T9431) or sixteen (T9432) isolated analogue input channels and notifies the processor module of the field device value and channel condition. Each channel provides digital state and analogue process value data to the processor for process monitoring, line monitoring and field fault detection.

The input module provides local module and channel status indications through its front panel LEDs, the same indications can be connected to application variables and viewed at the Workbench. Comprehensive diagnostics at both system and module levels provide clear indications which help rapid maintenance and repair.

The module incorporates signal and power isolation circuits,which separate each input channel from the rest of the system,protecting the controller from field faults. An independent watchdog arrangement monitors the module operation and provides additional fault containment by a shutdown mechanism should a fault occur.

When a controller uses an analogue input module in a dual or TMR configuration, plant operations personnel can fit a new input module without interrupting the input signals. 

Analogue Input Line Monitoring

Each analogue input module is set up through the AADvance Workbench. Monitoring levels for each analogue input channel are configurable at the module and the channel level. The default parameters are

• Fault: 0 to 3.8m

• Normal: 3.8 to 22.0mA

• Fault: > 22.0mA

Each input has five configurable voltage bands (there are eight distinct switching thresholds to allow hysteresis), each of which can be adjusted to provide line monitoring and field device diagnostics. 

The unit is mounted inside a secure protective box. The box is portable and when it is placed on a flat surface the lid can be lifted and secured in the open position with two bolts. It fully self contained and comes supplied with a set of modules and internal wiring to a display and control panel.
