Common way: no public side (all points of independence).
Input / output occupied points: 16 points (I/O distribution: output 16 points).
External wiring connection: 18 point terminal LD77MS4 Positioning control Manual LD77MS4 User's Manual.
1, the switch quantity acquisition and switch control and RS-485 bus are isolated from each other, and isolated from the whole system LD77MS4
2, the power supply line has anti reverse connect function, once the wrong power line,
Will automatically cut off the power to protect the entire module is not damaged.
With over-voltage protection function, when the voltage is too high, automatic disconnection,
Protecting the entire module is not damaged LD77MS4 Positioning control Manual LD77MS4 User's Manual.
3, RS-485 interface with 600W lightning protection and surge protection function, with 3000V photoelectric isolation.
4, the use of Modbus protocol, good general, can be very convenient and other systems,
Customers can also according to their own personal needs, custom related agreements, convenient and flexible.
5, communication lines using RS-485 bus, support for multiple modules in parallel use,
Easy to expand the system, good scalability LD77MS4 Positioning control Manual LD77MS4 User's Manual. "Universal output function: source type.

End cap.
High precision PWM control of the highest 200kHz.
In the PWM output mode, by setting the ON time and cycle time,
The duty cycle can be changed, and the minimum cycle time is 5 s.
In addition to lighting dimming control, simple motor control and heater control,
Can also be used to require high resolution detection equipment, such as a wide range of oscillators.
CPU built-in functions can be easily set through programming tools.
The built-in I/O function settings can be easily carried out through the parameters of the programming tool.
5 s units can be used forr high precision workpiece measurement in pulse measurement mode,
Can be used with a minimum of 5 s units of the input signal of the ON/OFF time (the shortest 200 s) for high precision measurrement LD77MS4 Positioning control Manual LD77MS4 User's Manual LD77MS4 Positioning control Manual LD77MS4 User's Manual.
For example, after measuring the ON time of the sensor input,
The "moving speed" and "length" of the workpiece can be accurately calculated ". "
