ANALOG OUTPUT MODULE AND VERIFYING APPARATUS THEREOF

摘要

PURPOSE: An analog output module and a verifying apparatus thereof is provided, which converts an analog value outputted as a control object of an industrial monitoring system and control system into a digital value and can verifies as to whether a wanted analog value is outputted. CONSTITUTION: An analog output module comprises: a decoding logic (10) for setting a card which a card address and a channel address is received from a CPU of a PC to decode and a D/A converting channel; a buffer unit (20) for buffering master data transmitted through a data bus according to WR control signal; a D/A channel output unit (30) for converting the buffered data of the output buffer unit (20) into an analog value to output the analog value to the industrial monitoring system and control system; a feedback channel setting unit (40) for setting a channel of an analog value to be feedback in the D/A channel output unit (30); an A/D converter (50) for converting the analog value into a digital value; and an input buffer unit (60) for buffering the converted digital data according to the control signal.
