1. Brief Introduction

LU-905F Multi-loop controller is designed for system which needs 8/16 points measuring display and control. It can loop detect and display signals of multi channels. User can choose at most 18 output of Programmable alarm (with auxiliary. The alarm’s output position can be set as user’s requirements. Besides, user can shield alarm function of one or more channels while the rest channels’ alarm functions are still active.

The controller has 2 display modes. It can automatically loop display each channel’s PV or fixed display one channel’s PV. When itinerantly displaying, the switching time can be set as users’ requirements. The controller adopting standard MODBUS protocol, has strong generality and high Reliability.
