Description

The 3674 is a dual digital output (DDO) module designed for safety-critical control programs where low cost is prioritized over maximum availability. It receives output signals from the main processors via a single parallel or series path and applies a 2-out-of-3 voting process to each switch, ensuring safe operation with just enough redundancy. The module is optimized for de-energize-to-trip control programs, providing reliable operation in the presence of most single faults.

Features

2-out-of-3 voting process for each switch
Voltage-loopback circuit for independent verification of output switch operation
Ongoing diagnostics on each channel and circuit
Hot-swap capability for online replacement of faulty modules
Mechanically keyed to prevent improper installation
Self-protecting design with no external fuses required
External termination panel (ETP) required for field connections
