Detailed data
T8403 ICS Triplex Trusted TMR 24 Vdc Digital Input Module
The T8403 is a module in the ICS Triplex series of programmable logic controllers (PLCs). The T8403 is an I/O module that is typically used for input and output operations in industrial control systems. It is integrated with the Triplex control system and can communicate with other controllers and modules in the system.
The T8403 can work with other modules in the ICS Triplex T8400 series, such as the T8401, T8402, etc., and they can be used for control, monitoring or other I/O functions.
The Trusted TMR 24 Vdc digital input module interfaces with 40 field input devices. Fault tolerance is achieved through a triple modular redundant (TMR) architecture within the module for the 40 input channels.
Each field input is replicated three times and the input voltage is measured using a sigma-delta input circuit. The resulting field voltage measurement is compared to a user-configurable threshold voltage to determine the reported field input state. The module can detect open and shorted field cables when a line monitoring device is installed at the field switch. The line monitoring function is independently configured for each input channel. The triple voltage measurement combined with the onboard diagnostic tests provides comprehensive fault detection and fault tolerance.
The module provides onboard sequence of events (SOE) reporting with a resolution of 1 millisecond. A state change triggers an SOE entry. The state is determined by a voltage threshold that can be configured on each channel.
Frequently asked questions about the product are as follows:
-What is T8403 ICS Triplex?
T8403 is a Trusted TMR 24V dc Digital Input Module produced by ICS Triplex. It is a triple module redundant 24V DC digital input module.
-What is the Sequence of Events (SOE) function of T8403?
The module has onboard Sequence of Events (SOE) reporting function with a resolution of 1ms. Any state change will trigger an SOE entry, and the state is defined according to the specific value of the configurable voltage of each channel.
-Can T8403 modules be hot-swapped?
Online hot-swappable can be configured using dedicated adjacent slots or smart slots to minimize downtime during maintenance.
