Detailed data
Invensys Triconex 3503E Digital Input Module
The Invensys Triconex 3503E is a fault-tolerant digital input module designed for integration in safety instrumented systems (SIS). As part of the Triconex Trident safety system family, it is certified for SIL 8 applications, ensuring robust functionality and reliability in critical industrial environments.
Product Features:
-Triple Modular Redundancy (TMR) architecture: Provides fault tolerance through redundant hardware, maintaining system integrity during component failures.
-Built-in diagnostics: Continuously monitors module health, supporting proactive maintenance and operational reliability.
-Hot-swappable: Allows module replacement without shutting down the system, minimizing maintenance-related downtime
-Wide range of input signal types: Supports dry contact, pulse, and analog signals, providing versatility for a variety of applications
-IEC 61508 compliant: Meets international standards for functional safety, adhering to strict safety requirements.
Technical Specifications
• Input voltage: 24 VDC or 24 VAC
• Input current: Up to 2 A.
• Input signal type: Dry contact, pulse and analog
• Response time: Less than 20 milliseconds.
• Operating temperature: -40 to 70°C.
• Humidity: 5% to 95% non-condensing.
Tricon is a programmable and process control technology with high fault tolerance.
Provides triple modular redundant structure (TMR), three identical sub-circuits each perform independent degrees of control. There is also a dedicated hardware/software structure for "voting" on inputs and outputs.
Able to withstand harsh industrial environments.
Field installable, can be installed and repaired on-site at the module level without disturbing field wiring.
Supports up to 118 I/O modules (analog and digital) and optional communication modules. Communication modules can connect to Modbus master and slave devices, or to Foxboro and Honeywell distributed control systems (DCS), other Tricons in peer-to-peer networks, and external hosts on TCP/IP networks.
Supports remote I/O modules up to 12 kilometers away from the host.
Develop and debug control programs using Windows NT system-based programming software.
Intelligent functions in input and output modules to reduce the burden on the main processor. Each I/O module has three microprocessors. The microprocessor of the input module filters and repairs the inputs and diagnoses hardware faults on the module.
