Overview
SK-6500-8 industrial touch screen host controller is an industrial control device with 7-inch true color display and four-wire resistive touchpad. It is equipped with high-performance Cortex M4 processor, supports large-capacity data storage of U disk, and has multi-channel signal access and alarm output functions.
Features
1. Sign in password function to prevent misoperation;
2. Free channel settings, flexible configuration;
3. Historical data U disk storage;
4. Historical alarm information is stored on a U disk.
5. The historical data recording time interval can be set.
6. Four alarm modes can be set freely.
7. Time display and setting functions.
8. Support up to 32 channels of 485 devices and 16 channels of 4-20mA devices.
9. Default 4-channel passive dry node output, expandable relay module.
Principle
The host reads the real-time data of the external detector as a host through the RS485-1 interface, and communicates with the external DCS or PLC system as a slave through the RS485-2 interface. It receives 4-20mA analog signal or RS485 digital signal from the detector for processing, display and storage. When the detection value reaches the preset alarm condition, the host can drive the built-in buzzer alarm and output the passive dry node signal through the relay.
Applications
Industrial process monitoring, environment safety monitoring, Gas detection system, PLC/DCS Data Transmission Service
Standards
ModbusRTU protocol
Steps
1. Connect the AC220V power supply to power the system.
2. Connect the external detector through the 24V power supply of the external terminal block and the RS485-1 interface.
3. Use the U disk to insert the U disk interface for Data storage;
4. Sign in password, system settings, channel configuration and alarm mode settings through Touchscreen;
5. Configure the slave address of the RS485-2 interface (if required).
6. Connect the relay output or 4-20mA input interface as required.
Notice
• When installing, please pay attention to the size of the wall hole on the back (large hole 11mm, small hole 5mm, hole spacing 250mm * 218mm).
• Ensure that the working Ambient Temperature is between -20~ 70 ℃, Humidity is 0~ 90% RH without condensation.
• The relay output is a passive dry node, the contact point capacity is 30V/3A or 250V/3A, please do not use it beyond the limit.
• The 4-20mA input interface is a three-wire connection method. Please pay attention to the interface definition (24V-, current input, 24V +) when wiring.
• The alarm record format stored to the U disk is CSV, and a single file can store 1 million records.
• Built-in buzzer alarm function You need to turn on the "Alarm Sound" option in "System Settings".
• Power consumption is less than 7W, output power is DC24V/2A, do not overload.
