TMR Safety Control and Galvanic Isolation

The T3420A operates as an analog acquisition component within the ICS Triplex safety-control architecture. Its 16 input channels support voltage and current signals, while the 16-bit ADC converts field measurements into digital values for system processing.

The specified 1500 V AC isolation separates the analog input circuitry from associated electrical domains. In addition, the 24 VDC supply uses redundant inputs to support the power arrangement specified for the module.

For safety-system integration, engineers should verify the actual system configuration, I/O allocation, and application-specific safety requirements before commissioning. Do not infer SIL3 or TMR 2oo3 certification for this individual module solely from the supplied specifications.

Frequently Asked Questions (FAQ)

Q: What analog signals does the ICS Triplex T3420A accept?

Q: What ADC resolution does the T3420A provide?
A: The T3420A uses a 16-bit ADC for analog signal conversion. Its sampling rate is configurable.

Q: What isolation and power characteristics does the T3420A specify?
A: The module specifies 1500 V AC isolation and a 24 VDC +/-10% redundant supply input. Typical power consumption is <= 5 W.

Field Installation Guidelines

• Install the T3420A in the designated ICS Triplex system carrier or chassis according to the applicable hardware installation documentation.
• Confirm module orientation and mechanical engagement before applying system power.
• Verify the field signal type before wiring each analog channel.
• Separate low-level analog wiring from high-voltage power conductors and high-noise switching circuits.
• Use appropriate shielded instrumentation cable where the application requires improved noise immunity.
• Terminate cable shields according to the plant grounding and control-system grounding scheme. Avoid unintended ground loops.
• Confirm the redundant 24 VDC supply connections and polarity before energizing the module.
• Check field wiring continuity and signal polarity before commissioning each channel.
• Verify the configured input range against the connected field transmitter or voltage source.
• Do not exceed the specified input signal ranges or isolation limits.
• Record channel assignments and signal types during commissioning to support subsequent maintenance.
