NOTICE!
Risk of malfunctions!
The edges of a signal must be strong enough (0.4 V/µs) to be recognized cor-
rectly by the module.
Put a 1 kW resistor between 0 V and the Z terminal when using a standard
output as time generator.
Proceed with the 5 V power supply 1 in the same way.
Each 5-V-power supply provides a current of 100 mA max. It is possible to par-
allel both integrated power supplies. In this case, the max. current is 200 mA.
