Introduction
With Siemens S7-200 PLC as a matster controller, XY600 batch controller is a presetting precision control equipment used in petroleum, chemical food industry and others. This controller is suitable for the batch control system comprising of a flow meter with pulse output, or a weighbridge with RS485 output, thermometer 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 users can choose options that suitable for their needs to form various functions, therefore completing precision batch loading/filling control of the materials.

Basic features
1. Real-time mass/volume, flow, temperature, density and time display;
2. Operating mode: online or offline;
3. Password verification function: including the password of the operators and the password of the system administrator;
4. Has the function of protection of data upon loss of power and continuing the original working point once the power supply is resumed;
5. Accurate control electromagnetic valves, two-stages valves, and regulating valves, etc.;
6. Interlock control function of the pump and valve;
7. Mixing control: control online proportional mixing of the fluids accurately;
8. Temperature compensation function (linear, GB/T 1885-1998 or API standard);
9. Automatic conversion function of mass/volume delivered;
10. Flow coefficient/overshoot setting;
11. Self-diagnosis test;
12. Anti-surge protection.
