Description
Product Overview
The ICS Triplex T8461 is a TMR digital output module with 40 channels, designed for high‑integrity actuation in safety‑critical systems. It delivers 0.75 A per channel across 5 isolated power groups (8 outputs each). The fully triplicated architecture ensures fail‑safe operation, making it ideal for emergency shutdown (ESD), fire & gas, and burner management applications requiring SIL 3 compliance.
Core Advantages
Triple Modular Redundancy
Fully triplicated with 2‑out‑of‑3 voting. Any single fault is automatically masked, guaranteeing continuous, safe output actuation without spurious trips.
Flexible Field Voltage Range
Accepts field voltages from 18 to 60 Vdc, accommodating diverse actuator and solenoid requirements. The 5 independent power groups allow segregated loads for enhanced diagnostics.
High Capacitive Load Capability
Release 3.5 supports up to 3500 µF at 0.75 A, making it suitable for driving large solenoids and valves with high inrush currents.

Installation Tips
Power Group Segregation
Distribute loads across the 5 independent power groups (8 outputs each) to isolate faults and simplify troubleshooting. Each group has its own field supply return.
Output Wiring
Use shielded cables for field wiring, especially in high‑EMI environments. Keep cable lengths under 30 m to minimise voltage drop and crosstalk.
Capacitive Loads
For loads >55 µF, ensure the module is Release 3.5 or later. It supports up to 3500 µF at 0.75 A, ideal for large solenoids with high inrush.
Hazardous Area
For intrinsic safety, use external barriers as specified. Follow ATEX/IECEx installation rules: certified glands, proper segregation, and observe temperature class.
Why Choose T8461?
Delivers 40 high‑current outputs in a compact 31 mm wide package. The TMR architecture eliminates single points of failure, while the 0.5 ms turn‑on/off delay ensures fast response for critical trips. Withstands harsh industrial environments and integrates seamlessly with ICS Triplex Trusted systems. The high capacitive load capability (3500 µF) reduces the need for external interposing relays, saving panel space and cost.
FAQs
Q1: What is the difference between Release 3.5 and earlier versions?
A1: Release 3.5 increases capacitive load support from 55 µF to 3500 µF at 0.75 A. Recommended for large solenoids or long cable runs.
Q2: Can I use the T8461 with a 48 Vdc field supply?
A2: Yes. The operational field voltage range is 18–60 Vdc, fully compatible with 48 Vdc systems. Ensure total group current stays under 6 A.
Q3: What does the 33 kΩ off‑state leakage mean?
A3: This is the effective leakage resistance when output is off. At 48 Vdc, leakage is below 1.5 mA, preventing false actuation of sensitive loads.
