Explosion Proof Batch Controller, Volume Controller for Industry Automation

Introduction

With Siemens S7-200 PLC as a mastercontroller, XY600 batch controller is presetting precision control equipmentused in petroleum, chemical and food industry, etc. This controller is suitablefor the batch control system comprising of a flow meter with pulse output, or aweighbridge with RS485 output, thermometer transmitted under 4-20mA, controlvalves(including the solenoid valves, multi-stages control valves or regulatingvalves), as well as the oil spillage electrostatic protection device. Utilizingadvanced PLC technology, the device provides flexible and easy-to-learnprogramming methods so that the users may choose options suitable for theirneeds to form various functions, therefore completing precision batchloading/filling control of the materials.

Features

* Real-time mass/volume, flow, temperature,density and time display
