Description
The module is implemented in PC104+ format. These modules are used for interfacing the boards with optical isolation digital and analog modules (optical isolation modules), measurement of frequency (duration) and phases of signals, carrying out of computing and timer operations, acceleration of logical and arithmetic operations, generation of PWM signals, conversion of codes, control of alphanumeric indicators, generation of time control diagrams and hardware event interrupts at inputs. The module uses field-programmable gate arrays (hereinafter referred to as the FPGA) and the In-System Programmable (hereinafter referred to as the ISP) technology, which enable changing algorithm of module operation directly in the system, without switching off the power supply.
