Brand New ICS Triplex T8403 Trusted Digital Input Module

The ICS Triplex T8403 is a Trusted TMR 24Vdc Digital Input Module with 40 channels. It is a highly reliable and versatile module that is suitable for a wide range of applications, including safety systems, process control, and automation.

Here are some of the key technical features of the T8403:

• Trusted TMR technology: The T8403 uses Triple Modular Redundancy (TMR) technology to ensure the highest level of reliability. This means that each input channel is monitored by three independent sensors, and any errors are automatically detected and corrected.

• Comprehensive diagnostics: The T8403 provides comprehensive diagnostics to help you identify and troubleshoot problems. This includes self-test, line monitoring, and on-board Sequence of Events (SOE) reporting.

• Opto/galvanic isolation: The T8403 features 2500 V impulse withstand opto/galvanic isolation to protect your system from electrical noise and interference.

• Hot-swappable: The T8403 can be hot-swapped on-line, which means that it can be replaced without shutting down your system. This is a valuable feature for applications where downtime is not acceptable.

Here are some of the key technical specifications of the ICS Triplex T8403:

• Number of channels: 40

• Input voltage: 24Vdc

• Input current: 20mA per channel

Description

The Field Termination Unit (FTU) is the section of the I/O Module that connects all three FIUs to a single field device. The FTU primarily contains passive components necessary for front-end signal conditioning, field signal overvoltage protection, and EMI/RFI filtering. When installed in a Trusted Controller or Expander Chassis, the FTU field connector interconnects to the I/O cable assembly attached at the rear of the Chassis. The SmartSlot link is passed from the HIU to the field connections via the FTU. These signals go directly to the I/O cable assembly and maintain isolation from the I/O signals on the FTU. The SmartSlot link is the intelligent connection between Active and Standby Modules for coordination during Module replacement. The Field Interface Unit (FIU) is the section of the Module that contains the specific circuits necessary to interface to the particular types of field I/O signals. Each Module has three FIUs, one per slice. For the TMR 24 Vdc Digital Input Module, the FIU contains an individual analog to digital (A/D) converter for each of the 40 field inputs. The FIU receives isolated power from the HIU for logic. The FIU provides additional power conditioning for the operational voltages required by the FIU circuitry. An isolated 6.25 Mbit/s serial link connects each FIU to one of the HIU slices.
