Description
Description: 1. Working voltage: DC12V (Range 6-25V)2. Working current: 8-10MA(12V)3. 8 photoelectric isolation Input ports (NPN low level active ), the input and output relationship can be set to associated (default) and non-associated through commands.4. 8 photoelectric isolated output ports,''open'' ''close'' ''Momentary'' ''Self-locking'' ''Interlock'' ''Delay'' 6 Commands.5. MODBUS RTU command, Support 03 06 16 function code.6. Under the ''Delay'' command ,the maximum delay is 255 seconds.7. MODBUS commands can be made serial HyperTerminal (serial assistant) OR ''Modbus Poll'' Enter.8. Under the MODBUS command mode, it can support up to 64 devices in parallel9. The default baud rate is 9600BPS. The baud rate can be selected through jumpers: 2400 4800 9600 19200BPS10. Size: 136 * 72 * 18mm(Only PCB Board);140 * 88* 40mm(with Din Rail Box)11. Weight:75g(Only PCB Board);175g(with Din Rail Box)12. MOSFET load: 3.5-5V is 2A; 5-9V is 4A; 9-30V is 5AIntroduction:
The MOSFET model is 20N06, and each output channel is an independent control unit, which does not interfere with each other. If the MOSFET is burnt out and it does not affect the work of other channels, just replace the MOSFET with a new one.The advantages and disadvantages relative to the relay board:Advantages: 1 small working current, 8-10MA (12V); 2 no sound when switching states; 3 light weightDisadvantages: 1 load current is small, within 5A; 2 can only control DC 3.5-30V voltage
Pin function:
V1(V2-V8): Load input positiveGO1 (GO2-GO8): load output negativeG1 (G2-G8): load input negativeNote: The output indicator(CH1/2...8 LEDs) is only valid when there is load power
DIN rail Box parameters:
Product model: UM72Color: greenWidth: suitable for PCB board width UM72(72mm)Insulation grade: flame-retardant VO gradeBackplane length: suitable for 136 mm PCB boardsNet weight: 99gInstallation: DIN35 and C45 rail
Application: PLC IO expansion boardSmart Home,Home Automation ,Wiser Home;PTZ CCTV CameraSecurity MonitoringIdentification system;Motor FW & BWAutomatic curtain control
Typical Applications:
MODBUS RTU command mode (HEX), you can control a variety of ways: Serial HyperTerminal Control (need to manually add the CRC), Modbus Poll software control (software automatically add the CRC), PLC or MCU process control
