Serial Modules

Do you need to add analog inputs/outpus to your current PLC?

Yes, Latin Tech Inc. is the right place.


You can easily connect our analog modules to any PLC brand you use or if you really want to save dollars use our SuperPLCs which already include analog inputs/outputs.


Ideal for:

Cold rooms

Air conditioning systems

Plastic Injection Machines

Gas or Electric Ovens

Weight Control Systems

and many more


Do you want to go further with your analog variables?

Then, please take a look to some possibilities

  • Assemble your own Data logger or Temperature logger using our T100Series PLCs
  • Perform real time control and monitoring using the well known Microsoft's EXCEL spreadsheet
  • Are you trying to read/control electrical parameters or needing RTUs? Then visit our section of Power monitoring
  • To monitor/control position, inclination or distance select one of our position transducers with analog output

Now take a look to our Serial modules and prices

Serial Modules

Now we offer you the possibility to connect different types of analog devices to any of our SuperPLCs or your preferred brand with these low-cost analog modules.Our distributed I/O modules can communicate to PC or any host controllers including PLCs. They have dual watchdog timers to detect the failure of the module and network. Output modules have power on value and safe value. It is a MUST for Data Acquisition and Control applications. With RS 485 communication, it can go long distance.


  • RS-485 Communication, therefore you can connect several modules in one network, and to almost any type of PLC's
  • Low cost
  • Low power
  • Expandable
  • Low cost systems with our powerful PLC T100
For example: Multiple units of I-7000 can be multi-dropped from a T100MD+ or MX PLC, allowing hundreds of analog I/Os to be connected to a single PLC. Since the PLC can also be a MODBUS slave this can also serve as an ultra low cost RTU subsystem.

We have written an application note and some sample .PC5 programs to work with these modules. They can be downloaded from the following link:
