hi,I need a device to which I can record a voice message and then when it receives the power ( 220vac or other) it recalls the recorded signal. I really don't know the name of the device that can perform this function, so please answer me.
Thanks, but I'm afraid I can't use it as I want the playback to be PLC controlled not by pressing the switch and the speaker to be an external oneThis is cheap, easy to take a part, pretty straight forward to reuse.

For $2.00 (plus shipping), it's a good deal. You get 30 seconds of recording, 3 AAA batteries, small case with built in battery holder, microphone, and mini speaker (not piezo). The ugly little troll is held on by two screws. White paint and made in China, probably not a good toy for the dog, or small children. Loud enough holding it in your hand, but not so much across the room. Needs amplified and larger speaker.
Common ground, not difficult to switch from a microcontroller, never worked with a PLC, but can't be much different. There is/was a website that went into good detail about these things, circuit diagrams and suggestions. Might post a link later. Most likely cheaper than any chip you can order, and this one is ready to roll. Just figured I throw the link up, as it's the simple/cheap route. Depends on what you want.Thanks, but I'm afraid I can't use it as I want the playback to be PLC controlled not by pressing the switch and the speaker to be an external one
