Product Description
The Triconex 3503E is a 32-point TMR Digital Input Module designed for safety and control applications. It utilizes Triple Modular Redundancy (TMR), providing high reliability by processing each input through three independent channels. The module ensures continuous system operation even in case of a fault, with optical isolation between the field and the control system.
Key features include self-test capabilities for stuck-ON conditions, hot-spare functionality, and continuous diagnostics that monitor the health of each channel. The 3503E supports a wide voltage range (20-42.5 VAC/VDC) and provides 1500 VDC isolation between field inputs and the control system.
Key Features
- TMR with Self-Test: Ensures redundancy and fault tolerance.
- Continuous Diagnostics: Monitors channel performance and triggers fault alerts.
- Hot-Spare Capability: Allows seamless module replacement without downtime.
- Wide Voltage Range: Supports 24 VAC/VDC, with a maximum of 42.5 VAC/VDC.
- Point Isolation: 1500 VDC isolation between field inputs and control system.
