Output type and control loop fit
The Omron E5EC-TPR4A5M-000 is a temperature controller with a relay output, per the description field. That means the control signal closes or opens a relay contact rather than sourcing a DC voltage or current loop — a fit for on/off or time-proportional control of heaters, contactors, or solenoid valves where the load current is within the relay's rated switching capacity.
