WEG PLC500 Programmable Logic Controller

Introduction

The WEG PLC500 is a well featured industrial Programmable Logic Controller (PLC) designed for medium to large-scaled automation applications. It incorporates onboard digital I/O, with additional I/O available through expansion modules where required. The PLC500 is programmed and configured using WEG’s WPS programming platform and includes Ethernet, RS485 and USB-C communication interfaces.
