Introduction

Moxa’s ioLogik E1261W-T is designed for Ethernet-based remote condition monitoring systems. With 3 RTD, 5 AI, and 12 DIO channels, the ioLogik E1261W-T’s I/O combination is ideal for monitoring wind turbines and environmental conditions. Unlike other remote I/O products, which are passive and must poll for data, the ioLogik E1261W-T supports active communication with Moxa’s patented Active OPC Server to seamlessly connect with SCADA systems in real time.This report-by-exception approach, which is new to PC-based monitoring, requires far less bandwidth than traditional polling methods.
