Product Details

3664 is high‑density TMR triple‑modular‑redundant digital output module for Triconex Tricon Classic safety instrumented system. It receives safety logic commands from main processor and outputs switching signals for field safety actuators.

32‑point commoned solid‑state output design,high channel density saves cabinet space. Adopts 2oo3 hardware voting mechanism,each channel controlled by three independent circuit paths,single‑path fault will not trigger unsafe output. Single‑channel 2A continuous driving capability,suitable for driving solenoid valves and relays directly. Supports field loop fault diagnosis to detect loop abnormal status.

Hot‑swap design allows module replacement without SIS system shutdown. Front‑panel LED indicates module running,fault and channel state. Widely deployed in petrochemical,oil‑gas and thermal‑power SIS safety racks for large‑quantity safety switching output.

Note:This is legacy EOL spare component,widely used for safety system spare‑part replacement.
