ICS Triplex | T8402| Trusted Dual 24 Vdc Digital Input Module
Product Overview
The T8402 Trusted Dual 24 Vdc Digital Input Module by Rockwell Automation interfaces with 60 field input devices. It utilizes a 'One-Out-Of-Two D' (1oo2D) voting architecture for fault tolerance, ensuring reliable operation in critical applications. Each of the 60 input channels is duplicated, and input voltages are measured using sigma-delta circuits. The module supports line monitoring to detect open and short circuit faults, which can be configured per channel. It also features on-board diagnostics, automatic self-test, and Sequence of Events (SOE) reporting with 1 ms resolution.
Key Features
- Channels: 60 duplicated input channels.
- Fault Detection: Comprehensive fault detection and tolerance via dual voltage measurement and diagnostics.
- Isolation: 2500 V impulse withstand opto/galvanic isolation.
- SOE Reporting: On-board SOE reporting at 1 ms resolution.
- Filtering: Configurable 50/60 Hz digital filtering to reduce noise.
- Hot Replacement: Supports hot-replacement using Companion or SmartSlot configurations.
- Safety Certification: TÜV Certified IEC 61508 SIL 3.
- Status Indicators: Front panel LEDs indicate module health and operational mode (Active, Standby, Educated).
Technical Specifications
- Input Voltage Range: 24 Vdc ± 10%.
- Input Current: 0 to 65535 mA (FIU internal supply current).
- Unregulated Input Voltage: -32768 to 32767 mV.
- Board Temperature: Measured in °C = input value / 256, range -32768 to 32767.
- Reference Voltages: DAC_X1, DAC_X2, DAC_X3, range -32768 to 32767 mV.
- Diagnostic Error Codes: Reported as integers for fault finding.
- Module Status: Active and Standby module chassis numbers, slot numbers, health status, and state.
- Fault Containment Region (FCR) Status: Monitored and reported.
- Primary Module Activation: Indicator for primary module activity.
- Simulation Mode: Option to simulate the active module.
