Product Summary
The Triconex 3501T module provides a robust, triple-modular redundant interface for 115 VAC or VDC field signals. This unit features 32 non-commoned isolated points. Its TMR architecture guarantees fault tolerance for critical safety applications. You get high integrity through full signal path triplication.
Theme Option A: Product Procurement & Buyer Guide
Why Choose the 3501T for Your Safety System?
Procurement managers need a module that ensures maximum uptime. The 3501T delivers exactly that with its true TMR design. Each channel processes data independently. This design prevents a single point of failure from stopping your process. You gain both safety and availability.
Critical Technical Specifications for Engineers
The module operates on a voltage range of 90-155 VAC/VDC. It supports a frequency range of DC or 47-63 Hz. The switching level from OFF to ON is > 86 VAC/VDC. The switching level from ON to OFF is < 28 VAC/VDC. This wide hysteresis prevents nuisance trips on noisy signals.
Understanding Point Isolation and Power Load
Each of the 32 input points offers optical isolation. Point isolation is rated at 1500 VDC per point. The nominal field power load per ON point is 1.5 watts. At the maximum field voltage, this load reaches 2.9 watts. The nominal input impedance is greater than 8.5 KΩ.
Selecting Compatible Termination Panels
You must pair this module with the correct panel. For non-commoned termination, use the 9561-110 panel. For basic termination, use the 9551-110 panel. The module also requires a specific fanned-out cable, the 9101-010. Ensure your BOM includes the 9141-010 ERT loopback cable.
Diagnostic Indicators for Immediate Status
The module provides diagnostic indicators for quick troubleshooting. You get one input status LED per point. The module status shows PASS, FAULT, or ACTIVE. A fault indicator points to a specific channel issue. This design allows for rapid identification of problems.
