Abstract
An output circuit for a programmable sequence controller wherein a load drive element control circuit is responsive to a command signal stored in a memory circuit for controlling a load drive element connected between a load and a first electric supply. Between a power input terminal of the load drive element control circuit and a second electric supply, there is connected in series a switching element, which is switched on in response to a signal applied from a supply voltage detecting circuit only when the voltage level of the second electric supply is not lower than a level sufficient for normal and reliable operation of the load drive element control circuit.
