Introduction
With Siemens S7-200 PLC as a master controller, XY600 batch controller is a presetting precision control equipment used in petroleum, chemical and food industry, etc. This controller is suitable for the batch control system comprising of a flow meter with pulse output, or a weighbridge with RS485 output, thermomerter transmitted under 4-20mA, control valves(including the solenoid valves, multi-stages control valves or regulating valves), as well as the oil spillage electrostatic protection device. Utilizing advanced PLC technology, the device provides flexible and easy-to-learn programming methods so that the users may choose options suitable for their needs to form various functions, therefore completing precision batch loading/filling control of the materials.
Features
