3564 TRICONEX Digital Input Module
The 3564 TRICONEX Digital Input Module is a component designed for the Triconex safety instrumented system (SIS), which is widely used in critical industrial applications like oil & gas, petrochemicals, power generation, and nuclear facilities. Here’s a detailed breakdown of its key features and specifications:
Key Features of the 3564 TRICONEX Digital Input Module:
- Voltage Rating:
- Operates on 24 VDC (Direct Current), a common standard for industrial control systems due to its reliability and safety in hazardous environments.
- Channel Configuration:
- Typically provides 16 digital input channels, allowing it to monitor multiple binary signals (e.g., on/off, high/low, presence/absence).
- Each channel can detect whether a voltage is present (logic “1”) or absent (logic “0”).
- Triplicated Architecture (TMR):
- As part of the Triconex Triple Modular Redundant (TMR) system, the 3564 module includes three independent channels for each input.
- This redundancy ensures fault tolerance—if one channel fails, the other two can still provide accurate data, maintaining system safety and reliability.
- High Reliability & Safety:
- Designed for SIL 3 (Safety Integrity Level 3) applications, meeting stringent safety standards (IEC 61508, IEC 61511).
- Features self-diagnostics to detect faults in the module or wiring, triggering alarms or safe shutdowns if necessary.
- Field-Side Connectivity:
- Supports isolated inputs, preventing electrical interference between channels or external systems.
- Compatible with dry contacts (switch closures) or wet contacts (voltage sources like sensors or solenoids).
- Hot Swapping & Redundancy:
- Modules can be replaced without powering down the system, minimizing downtime.
- Works in conjunction with redundant power supplies and controllers for uninterrupted operation.
- Environmental Robustness:
- Rated for industrial temperatures (typically -20°C to +70°C).
- Resistant to vibration, shock, and electromagnetic interference (EMI/RFI).
Typical Applications:
- Emergency Shutdown (ESD) Systems
- Burner Management Systems (BMS)
- Fire & Gas Detection
- High-Integrity Pressure Protection Systems (HIPPS)
- Turbomachine Control

Integration with Triconex Systems:
- The 3564 module connects to a Triconex controller (e.g., Tricon, Trident, or Tri-GP) via a TriBus backplane.
- Configured using TriStation 1131 software, which allows logic programming, diagnostics, and HMI integration.
Maintenance & Support:
- LED Indicators: Provide status for power, channel health, and diagnostics.
- Firmware Updates: Can be applied in the field to add features or patch vulnerabilities.
- Spare Parts: Critical for minimizing downtime in safety-critical systems.
Where to Buy/Source:
- Authorized Distributors: Schneider Electric (owner of Triconex), MRO suppliers, or industrial automation resellers.
- Second-Hand/Refurbished: Available from specialized vendors, but ensure certification and warranty for safety-critical use.
If you need pricing, datasheets, or replacement parts, contacting Schneider Electric directly or an authorized partner is recommended. For troubleshooting, refer to the module’s manual or Triconex technical support.
