Plug-and-Play SIL-3 Temperature Safety for Critical Processes
1. Why 3708E?
When temperature is the last line of defence against a run-away reactor, turbine or heater, the TRICONEX 3708E delivers 16-channel triple-redundant thermocouple acquisition certified to SIL-3. Every channel is galvanically isolated, cold-junction compensated and continuously self-checked—so you meet IEC 61511 without extra wiring or external relays.
