TRICOENX 3624 Digital Output Module | 16-Ch 24VDC TMR Safety I/O
In Stock & Ready to Ship | 12-Month Warranty | SIL 3 Certified
Product Overview
The TRICOENX 3624 is a high-performance, fault-tolerant digital output module engineered specifically for safety-critical industrial applications. Designed with Triple Modular Redundancy (
TMR) architecture and SIL 3 certification per IEC 61508, this module serves as the "last line of defense" in safety instrumented systems (SIS), ensuring fail-safe operation even in the event of component failures or electrical interference. Seamlessly integrating into TRICOENX safety platforms, it delivers reliable digital control for critical processes across multiple industries, minimizing downtime and safeguarding personnel, equipment, and production integrity.

Key Features
- Triple Modular Redundancy (TMR) Architecture: Equipped with three independent circuits and 2oo3 voting logic, the module maintains safe operation even if one component fails, eliminating single-point failures and ensuring maximum reliability for mission-critical systems.
- SIL 3 Certification: Fully compliant with IEC 61508 and IEC 61511 standards, achieving SIL 3 safety integrity level—ideal for high-risk applications where safety compliance is mandatory.
- 16 Supervised Digital Outputs: Provides 16 channels of 24VDC digital output, with 2A per channel and 8A total per module, supporting inductive loads (e.g., solenoid valves) with integrated flyback diode protection.
- Continuous Diagnostic Monitoring: Boasts over 99% diagnostic coverage with real-time self-testing, detecting wiring faults, load failures, and power supply anomalies instantly to prevent system malfunctions.
- Hot-Swappable Design: Supports on-line module replacement without system shutdown, reducing maintenance time and ensuring uninterrupted operation of critical processes.
- Wide Compatibility: Seamlessly integrates with TRICOENX chassis, main processors, analog I/O, and communication modules, supporting protocols like Modbus, RS-485, and Ethernet for flexible system configuration.
