The Triconex 3664 Dual Digital Output Module is designed to support safety-critical control programs with robust diagnostics and redundancy mechanisms while maintaining cost efficiency. Below is a detailed overview of its specifications and operational features.
Key Features
- Dual Redundancy Design:
- Implements 2-out-of-3 voting on each switch for safe and reliable output generation.
- Optimized for safety-critical applications where cost efficiency is prioritized over maximum availability.
- Voltage Loopback Circuit:
- Verifies the operation of output switches, ensuring functionality even without load presence.
- Triggers the LOAD/FUSE alarm when field voltage mismatches the commanded output state.
- Comprehensive Diagnostics:
- Continuously monitors each channel and circuit.
- Activates the Fault Indicator and chassis alarm signal upon diagnostic failure.
- Hot-Spare Capability:
- Allows online replacement of faulty modules without system downtime.
- Mechanical Keying:
- Prevents improper installation into the chassis.
