Limited Edition T8461 | Ics Triplex | Tmr 24/48 Vdc Digital Output Module Pro Version [vb1ti0AC]

DESCRIPTION

The T8461 is a high-performance TMR (Triple Modular Redundant) digital output module designed by ICS Triplex. It is used in safety-critical applications where reliability and fault tolerance are essential. The module operates at 24/48 Vdc and provides precise and robust output control.

Key Features

• Output Channels: 40 TMR output channels per module
• Isolation Groups: Five isolated groups of eight outputs each
• Output Array: Six-element voted output array for fault tolerance
• Diagnostics and Self-Test: Comprehensive internal diagnostics and self-testing capabilities
• Safety Compliance: Meets IEC 61508 SIL-3 standards for safety-critical applications
• Line Monitoring: Per-channel line monitoring to detect field wiring and load failures
• Automatic Over-current Protection: Each output circuit has built-in over-current protection, eliminating the need for external fuses
• Opto-Isolation: 2500V dc for enhanced safety and signal integrity
• Hot Replaceable: Modules can be replaced without interrupting operation
• Status Indicators: Front panel LEDs provide status for each channel, along with module fault and status indicators

Fault Detection and Replacement

• Fault Indication: Module faults are flagged by the TrustedTM TMR Processor, signaling the need for replacement
• Continued Operation: System continues to operate until a replacement module is installed
• Replacement Modules: Can be located in a standby slot or a designated SmartSlot with a temporary connection to the TrustedTM Termination Assembly

Configuration and Installation

• Configuration Tool: Configured using the TrustedTM Toolset on an Engineering Workstation
• Mechanical Keying: Prevents incorrect insertion of modules into slots
• Line Monitoring: Configurable per channel to ensure detection of field wiring and load failures
