This document provides introductory information on the electrical specifications, functions, and wiring of DVP-EH2-L/DVP-EH3-L. The program and instructions for DVP-EH2-L/DVP-EH3-L are compatible with the DVP-EH2/DVP-EH3 series. The document also includes guidelines for purchasing peripheral devices. DVP-EH2-L/DVP-EH3-L is an open type device that should be installed in an enclosure free of airborne dust, humidity, electric shock, and vibration. The enclosure should prevent non-maintenance staff from operating the device, and proper grounding is necessary to prevent electromagnetic interference.
This guide provides the necessary information to install and wire the AELTA DVP‑EH3‑L programmable logic controller. It includes safety warnings, power‑input requirements, and detailed specifications for input and output points.
The manual describes DIN‑rail mounting, terminal torque values, wiring recommendations, and protection circuits. It also outlines the PLC’s electrical ratings, such as supply voltage, fuse capacity, and current limits, to ensure reliable operation in industrial control applications.
| Fuse capacity | 2A 250VAC |
|---|---|
| Power consumption | 60VA |
| DC24V current supply | 500mA |
| Withstand voltage | 1500VAC primary‑secondary, 500VAC secondary‑PE |
The terminal screws should be tightened to 5 – 8 kg‑cm (4.3 – 6.9 in‑lb).
Do not leave terminals empty, do not run input signal cables and output power cables in the same circuit, and use 1.6 mm copper conductors.
