The switch input and output module is a device which can collect the input / output of the switch signal,
Digital I/O modules are often called LD77MH4
The switch signal is collected to the computer or the computer to send the relevant instructions through the RS-485 bus to control the switch of the switch,
Can also be carried out through the RS-485 bus communication,
Remote control switch.
Communication protocol is a standard Modbus protocol or custom protocol LD77MH4 PDF datasheet. RS-232, RS-422/485.
Transmission speed: 230.4kbps.
MC protocol.
Communication protocol support function.
Can only be used on the ch1 side.
Device for immediate communication
Communication protocol support function through Works2 GX,
Can easily set the required agreement with the other equipment communication.
In addition, only the communication protocol library is required to select the equipment to be carried out,
Immediate connection LD77MH4 PDF datasheet.
The creation and editing of communication protocols are simple and easy to implement, even if there is no connection equipment in the communication protocol library,
Can also simply create a corresponding protocol for communication.
The content of the communication protocol that can be created in the list,
Can also be simply edited. Input points: 32 points.
Rated input voltage: DC24V.
Common way: 32 point / public end.
Input / output occupied points: 32 points (I/O distribution: 32 points).
External wiring connection mode: 40 pin connector.
The input and output module is also called control module, which can output signal when there is control requirement,
Or provide a switch signal to the controlled device,
At the same time, the feedback signal of the equipment can be received to report to the host computer,
Is ann important part of the fire alarm linkage system,
The input and output modules in the market can provide a pair of passive normally open / normally closed contacts,
For controlling the controlled equipment, the module of the parrt can be set by the parameters,
Set to active output, corresponding to the two input and output modules, multiple input and output modules, and so on LD77MH4 PDF catalog LD77MH4 PDF catalog.
