Input points: 8 points.
Rated input voltage: AC100 ~ 120V.
Common way: 8 point / public end.
Input / output occupied points: 16 points (I/O distribution: 16 points).
External wiring connection: 18 point terminal.
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 an 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 part 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 LD75D2-CM PDF datasheet LD75D2-CM PDF datasheet LD75D2-CM Output points: 32 points.
Output type: leakage type.
Rated output voltage: DC12 ~ 24V.
Max load current: 0.1A/1 point.
Protection function: have.
Common way: 32 point / public end.
Input / output occupied points: 32 points (I/O distribution: output 32 points) LD75D2-CM PDF datasheet.
External wiring connection mode: 40 pin connector.
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.
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. Output points: 16 points.
Output form: bidirectional thyristor output.
Rated output voltage: AC100 ~ 240V.
Max load current: 0.6A/1 point.
Common way: 16 point / public end.
Input / output occupied points: 16 points (I/O distribution: output 16 points).
External wiring connection: 18 point terminal.
1, the switch quantity acquisition and switch control and RS-485 bus are isolated from each other, and isolated from the whole system.
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.
3, RS-485 interface with 600W lightning protection and surge protectioon function, with 3000V photoelectric isolation LD75D2-CM PDF catalog.
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, convennient and flexible LD75D2-CM PDF catalog.
5, communication lines using RS-485 bus, support for multiple modules in parallel use,
Easy to expand the system, good scalability.
