What the 2-Current AC Volt Input Means for Your Loop
The Omron E5EC-TCC4A5M-000 is a temperature controller configured for a 2-current AC volt input — it reads two AC current or voltage signals, not a standard thermocouple or RTD. That makes it the right pick for applications where the process variable comes from a current transformer or a voltage divider, not a direct temperature probe.
