DRIVE PAK 311-435.7 Pulse input module

DRIVE PAK 311-435.7 Pulse input module

The dc voltage ratings available are 30/34V, 48/54V, 110/125V and 220/250V. Where voltage sources which are higher than 30V are used, external dropper resistors are connected in series with the positive supply rail. Check that the dc supply voltage is present and that the polarity is correct between terminals 13 and 14 on the relay case terminal block when the module is removed from the case. Note that when the module is in the case and the supply is connected, the voltage across the terminals may be less due to the voltage drop across the external dropper resistor RD (if fitted).

Printed circuit board tests 

If all the connections are intact and the supplies are of the correct voltage and polarity, it is likely that the fault will lie somewhere on the PCB. Proceed to the next two sections to try to confirm this.Check that the ac is present between terminals 27 and 28. For the 380/440V ac version of the inverse time delayed overvoltage relay (MVTD 12), check that the series resistors are fitted in series with the ac supply terminals.
