The T3480 is a high‑integrity guarded analog output module from ICS Triplex, engineered for safety‑critical applications in oil & gas, chemical, power generation, and turbomachinery control. The T3480 converts digital safety logic commands into precision 4‑20 mA or 0‑10 V signals to drive field devices such as control valves, actuators, and variable speed drives. Available in both Trusted TMR (8‑channel) and Regent (6‑channel) variants, the T3480 employs triple‑modular or dual‑redundant architectures with hardware‑level voting and comparison of drive/reference signals. With 12‑bit resolution, ±0.5% accuracy, 2 kV isolation, and SIL 3 certification, the T3480 delivers fail‑safe analog output for demanding safety instrumented systems (SIS).
Hardware‑Level Redundancy – TMR architecture with 2oo3 voting; any single channel failure does not affect the output, and a second fault defaults to a safe state.
Drive‑Reference Comparison – Dual D/A converters per channel; output is only enabled when the drive and reference signals match, ensuring fail‑safe operation.
Hot‑Swappable – Modules can be replaced without system shutdown, minimizing downtime.
Parallel Redundancy – Two modules can be connected in parallel; standby module takes over in <5 ms with bumpless transfer.
SIL 3 Certified – TÜV‑certified per IEC 61508 for use in safety instrumented systems.
Comprehensive Self‑Diagnostics – Continuous monitoring of D/A converters, voter logic, and output loops; detects open/short circuits.
8 (Trusted) or 6 (Regent) isolated analog output channels
4‑20 mA or 0‑10 V output (software‑configurable)
12‑bit resolution with ±0.5% FS accuracy
2 kV RMS galvanic isolation (channel‑to‑system)
1 ms update cycle for fast loop response
1 ms SOE recording with ±10 ms timestamp
Front‑panel LED indicators (active/fault, shutdown, per‑channel status)
Hot‑swappable; supports parallel redundant configuration
Built‑in loop integrity monitoring and self‑diagnostics
Wide operating temperature: -40°C to +85°C (extended variant)
TÜV SIL 3 certified (IEC 61508)
Modbus RTU communication via Trusted backplane
The T3480 receives triplicated write data commands from the processor over the I/O Safetybus. Onboard, the triplicated data are routed to two independent voter and logic sections. Each section independently votes the data and drives one 12‑bit D/A converter per output channel.
For each channel, one D/A converter generates the drive signal (actual output), while the other generates a reference signal. The module continuously compares these two signals; they must match for the output to be enabled. If they disagree, the module enters a fail‑safe state, shunting the output.
In parallel redundant configurations, two T3480 modules are cross‑strapped via STATUS OUT/IN signals. One module actively controls the load while the standby module tests its circuits with outputs shunted to AGND. If the active module fails, the standby takes over in <5 ms with bumpless transfer.
Comprehensive self‑testing covers D/A converters, voter logic, Safetybus interfaces, and output loops. Faults are annunciated via front‑panel LEDs and communicated to the system for predictive maintenance.
Q1: What is the difference between the Trusted TMR and Regent versions of the T3480?
A1: The Trusted TMR T3480 features 8 output channels with triple‑modular redundancy (3 independent processing paths). The Regent T3480 has 6 channels with dual‑redundant design.
Q2: What output signals does the T3480 support?
A2: The T3480 supports both 4‑20 mA current loops and 0‑10 V voltage outputs, software‑selectable per channel.
Q3: Can the T3480 be replaced without shutting down the system?
A3: Yes. The T3480 is hot‑swappable. In parallel redundant configurations, either module can be removed while the other continues controlling the load without interruption.
Q4: What safety integrity level does the T3480 achieve?
A4: The T3480 is TÜV‑certified for SIL 3 per IEC 61508, suitable for use in safety instrumented systems (SIS).
Q5: How does the T3480 ensure fail‑safe operation?
A5: Each channel uses dual D/A converters—one for the drive signal and one for a reference. The output is only enabled when both signals match. If they differ, the module defaults to a safe state.
