Relay module

Special purposed chassis SFX is made for building multipurpose, multichannel systems of electronic modules functional testing and also for systems of information gathering, technical process management and integrated circuits complex testing. Wide range of instrumental modules allows to create on SFX chassis basis expand functional testers which are adapted to certain customer’s requirements. 

SDIO modules are developed for functional control of digital devices at maximum frequency 50 MHz and they are used FT-17 and FTT-17complexes.

SDIO modules allows to perform digital tests at frequency between 5 Hz and 50 MHz when driver input signal level changes from 0.7 V to 12 V. Each SDIO module consists of 32 or 128 (for SDIO32/50 and SDIO128/50) bidirectional input-output channels with driver maximum loading capacity 150 мА which allows parallel connection of several microchips outputs to one module output channel. The comparator’s response level is also regulated programmatically between 0 and 11.5 V.

SDIO modules set uses general to the entire modules graphic environment for development of testing vectors. The testing vector includes setting digital sequence and “answer” received from the tested module and pre-settings for all the tested boards as well.

Module software is a set of dynamic libraries with detailed description of necessary functions for development of user software in any object-based environment (С++, Visual Basic, ATEasy and others). In contents of delivery there is virtual instrumental panel which in dialogue mode provides access to the main module’s abilities.

The module is made to generate orthogonal pulses with frequency between 1 and 75 000 Hz and to set up charges which help to imitate resistible charges within 0.5 and 120 kOhm. The module is for imitating automobile sensors signals (frequented and resistible) and in general can be used to check automobile devices (tachometer, speedometer, devices combination, etc.).
The module includes 2 independent impulse generators of squared shape with 50% pulse ratio and set of 8 electronic charges which values of reluctance are set programmatically.

Package content includes also virtual instrument panel which in dialogue mode provides access to the main modules possibilities.
