Abstract
PURPOSE:To send a DP signal by using a control signal controlling ON/OFF of a relay as a new control signal for a desired dial pulse signal based on a delay time till the relay is changed over so as to use a conventional relay. CONSTITUTION:In order to measure the response speed of a Di relay 3, a CML relay 2 is turned off, an output terminal of a control circuit 6 is brought into an 'H' level to turn on/off the Di relay 3. In bringing the level of a control port Di8 to 'H', the Di relay 3 is turned on and the input terminal goes to an 'L' level. The level of the input terminal goes to 'L' in time t1 after the control port Di8 reaches 'H'. It is the ON delay time of the Di relay 3. Similarly, the OFF delay time t2 is obtained. Taking times to turn ON/OFF the Di relay 3 as TON, TOFF, it is required to keep the time of 'H', 'L' of the control port Di8 as TON+t1-t2 and TOFF+t1-t2.
