Safety Rating |
SIL 3 (IEC 61508/61511) |
The T8431 is a SIL 3‑certified 40‑channel analog output module from ICS Triplex‘s Trusted TMR platform. It converts digital safety commands into 4‑20 mA signals for critical actuators. The T8431 uses hardware‑level 2‑out‑of‑3 voting on every channel, ensuring fail‑safe operation. With HART support and hot‑swap capability, the T8431 is ideal for safety instrumented systems in oil, gas, and power industries.
True TMR with 2oo3 hardware voting – no single point of failure
Triple independent D/A paths per channel for maximum integrity
Hot‑swappable without process interruption
Comprehensive self‑diagnostics with online fault reporting
SIL 3 certified for demanding safety applications
40 outputs in 5 isolated power groups of 8 channels each
4‑20 mA or 1–22 mA configurable range
HART pass‑through for remote diagnostics and calibration
Short‑circuit and over‑current protection
<50 ms step response for fast loop control
Internal temperature monitoring and compensation
Front panel LEDs for channel status and fault indication
Compatible with T8100 and T8300 chassis
IEC 61508 / IEC 61511 – SIL 3 capable
TÜV certified for functional safety
ATEX / IECEx for hazardous area installations (depending on system)
CE marked for EMC and Low Voltage Directives
UL / CSA recognized components (per system integration)
Q1: What is the TMR architecture of the T8431?
A1: Triple Modular Redundant means three independent processing paths per channel; 2‑out‑of‑3 voting ensures the output is correct even if one path fails.
Q2: Can the T8431 be replaced while the system is running?
A2: Yes, it supports hot‑swapping; replacement does not interrupt process control.
Q3: What is the maximum current output per channel?
A3: Each channel can output up to 22 mA, with a nominal range of 4‑20 mA for standard applications.
Q4: Does the T8431 support HART communication?
A4: Yes, HART pass‑through allows remote configuration and diagnostics of connected field devices.
Q5: What safety integrity level does the T8431 achieve?
A5: It is certified for SIL 3 (IEC 61508/61511) for use in safety instrumented systems (SIS).
