E5CN/E5CN-U is a digital temperature controller from Hitachi that has enhanced functions and performance, improved indication accuracy and preventive maintenance function.
The E5CN and E5CN-U are 48 × 48 mm basic‑type digital temperature controllers offering improved indication accuracy and preventive‑maintenance functions. They support universal thermocouple or platinum‑resistance inputs as well as analog current/voltage inputs, and can be equipped with various control and auxiliary outputs.
The handbook includes ordering information, accessory part numbers, detailed specifications such as power‑supply ranges, output types, sampling period, and alarm settings, plus wiring diagrams for terminal blocks and plug‑in sockets. Warranty and safety notes are also provided.
| Indication Accuracy (Thermocouple) | +0.3% of PV |
|---|---|
| Power Supply Voltage | 100 to 240 VAC, 50/60 Hz (or 24 VAC/VDC for D models) |
| Control Output Type (Relay) | SPST‑NO, 250 VAC, 3 A (resistive load) |
| Sampling Period | 250 ms |
| Ambient Operating Temperature | -10 °C to 55 °C |
| Number of Auxiliary Outputs | 1 or 2 (model‑dependent) |
They accept universal thermocouple or platinum‑resistance thermometer inputs and, for analog models, current (4‑20 mA) or voltage (0‑10 V) inputs.
Depending on the model, the controller can have up to two auxiliary outputs.
The controller samples the process variable every 250 ms.
Models without a “D” in the part number use 100‑240 VAC (50/60 Hz); models with “D” use 24 VAC or 24 VDC.
