LTR42 Output module for digital signals
Output module for digital signals
 |
|
Designed for discrete control of technological processes, laboratory and production equipment, industrial automation systems.
LTR42 is used in circuits of automatic ON/OFF or switching of equipment operation modes, both when directly connected to control circuits, and for controlling more powerful intermediate actuators: relays, contactors, etc.
37-pin interface terminal block board
DB-37F-increaser

Beta version. LCOMP library for Windows XP/Vista/Win7/Win8/Win10 32 and 64-bit versions with drivers. The installer and drivers are digitally signed. The library is built on the basis of modern WDM-drivers rewritten on WDF. It includes the WDM driver itself for L-CARD hardware, the DLL library with source code, programming examples, electronic description, etc. The LCOMP library provides support for almost the entire range of products: PCI boards, USB modules. ISA support is excluded.
The library includes “L-Graph I” software. L-Graph I supports the following devices: L-1450, L-761, L-780, L-783, L-791, E14-140, E-154 and E14-440. Files recorded by L-Graph I can also be read and processed using the demo-version of PowerGraph v.3.X. -
ltrd-setup.exe (filesize: 1 467 072 bytes, date: 25.11.2020)
The ltrd service. Version 2.1.8.6. Provides communication with LTR crates. It is a replacement for the LTRserver software while maintaining the compatibility of the program interface. ltrd is designed for the same purpose as LTRserver, but it is a service that runs when the system is started. The graphical interface to the service is provided by a separate LTR Manager program.
Attention! Only one of the programs ltrd or LTRserver can work at a time.
