OMRON E5EK-PRR2-500 Digital Temperature Controller – E5EK Series
Imagine a critical thermal process running unattended — a plastic injection mold, a pharmaceutical drying oven, or a food-processing line — with no reliable temperature regulation. Without a precision controller like the OMRON E5EK-PRR2-500, temperature deviations go uncorrected, product quality collapses, equipment overheats, and costly production shutdowns follow. The E5EK-PRR2-500 eliminates that risk, delivering tight closed-loop PID control that keeps your process within specification around the clock.
Within OMRON’s E5EK series — a benchmark platform for DIN-rail-mounted digital temperature controllers — the E5EK-PRR2-500 occupies the relay-output, 100–240 VAC tier, making it the go-to choice for engineers who need robust switching capability without the added complexity of analog or SSR-drive outputs. Trusted by OEMs and system integrators across Asia, Europe, and the Americas, the E5EK series has earned its place as one of the most widely deployed temperature controllers in global industrial automation.

Frequently Asked Questions
- Q: What does “PRR2” mean in the model number E5EK-PRR2-500?
- A: “PRR2” denotes the output configuration — P indicates PID control capability, and RR2 specifies dual relay outputs (control relay + alarm relay). “500” refers to the 100–240 VAC power supply version.
- Q: Is the E5EK-PRR2-500 compatible with both thermocouple and RTD sensors?
- A: Yes. The E5EK-PRR2-500 accepts a wide range of thermocouple types (K, J, T, E, L, U, N, R, S, B, W) and platinum RTD inputs (Pt100, JPt100), selectable via front-panel or communication settings.
- Q: Can this controller communicate with an OMRON PLC?
- A: Yes. The built-in RS-485 port supports OMRON’s CompoWay/F protocol, enabling direct integration with OMRON CJ, NX, and CP series PLCs for remote parameter read/write and process monitoring.
