3482 Triconex Analog Output Module High-Current TMR

Overview

The 3501T is a high-integrity Triconex Digital Input Module designed for Triple Modular Redundant (TMR) safety architectures. Operating at 115 VAC/VDC, this 3501T module features 32 non-commoned, opto-isolated points that provide galvanic separation between field sensing and logic processing. With 100% triplication of signal paths, the unit ensures maximum availability and failsafe operation for critical industrial processes.

Oiltech Controls’s Insight

• The 3501T excels in electrical noise rejection due to its 32 VAC/VDC hysteresis.
• Independent microprocessors per channel facilitate high-speed voting at the main processor level.
• Fault indicators distinguish between channel anomalies and total module failures to prevent nuisance trips.
• The module is guaranteed to operate properly even in the presence of a single channel fault.

Buying Guide & FAQ

How does the 3501T handle a single channel fault?

• The module uses 2-out-of-3 voting; a single fault activates the Fault LED but does not stop module operation.

What is the difference between commoned and non-commoned panels?

• Non-commoned panels (9561-110) maintain total isolation for each point, whereas commoned panels share return lines.

Can the 3501T be used for 125VDC battery monitoring?

• Yes, its 90-155 VDC range makes it ideal for utility-grade 125VDC digital feedback signals.

Is a stuck-test diagnostic available for the 3501T?

• No, the 3501T relies on triplicated channel comparisons for fault detection rather than active pulsing.

How do I confirm the module is active in the Tricon chassis?

• The “ACTIVE” LED will be illuminated, indicating the module is currently processing field data. Reach us at +86 158 8020 0923 for setup help.
