Omron CJ1M-CPU11 PLC Teardown

Hi,

Recently I asked a lecturer what processor the OMRON PLC's generally used and all I got was a dumbfounded look and a who cares reaction.
Fast forward a couple of months I purchased a used one off eBay and to initially program the unit I had to pull it apart. I'll go into more detail about that in another post but I thought why not take some photos and identify the main components on the board. I couldn't find any reference on the net as to what's inside one of these units so I thought some people out there might find it interesting. As expected ,however, there's not much to them.



The main chips and their datasheets are:

Renesas HD6437145 - Datasheet
Cypress - CY7C1021CV33 - Datasheet - $6.94
Maxim – MAX3243 - Datasheet - $7.67
Renesas – R1LV0408CSA - Datasheet - $19.85
SN74LV14A - Datasheet - 72c

Thanks for reading

Justin

Audio Mixer - Part 1 - Playing with OP-AMPS

Audio Mixer - Part 1 - Playing with OP-AMPS When I decided to do this mixer project I first started to play around with op-amps. This entry was originally done as a little report for myself on my first experience using an op-amp. So its mainly theory and simulation. In the next entry I'll breadboard up an op-amp circuit using the OPA-2134 that will be used in the mixer circuit. The objective is to demonstrate a straight forward, easy to understand, example of the operation and use of Op Amps in a circuit. The circuit consists of an LM324 Quad Op-Amp, Microphone and a speaker. To get a decent audible level from the selected speaker, a Peak to Peak (PP) voltage of 12V is required. This was calculated by feeding a source signal from a wave generator and adjusting the PP value. Using the oscilloscope it was also determined that the microphone produced a PP value of roughly 20mV. This leads to the following formulas:                  Required Output (Vout) = 12V

Mixer - Part 2 - Using the OPA2134

Hi, This is just a quick post showing my tests of the OPA2134 OPAMP from TI. Datasheet - http://www.ti.com/lit/ds/sbos058a/sbos058a.pdf I'm not sure whether or not I'll use this in the final design but as its touted as a "High Performance Audio Op Amp" I figured it's not a bad place to start. At around $7 AUD its not necessarily the cheapest Op Amp around. It's available in single, dual and quad versions but as I'm after individual control of the Left and Right channels, I chose the 2 channel 2134. Now to the breadboard! If you read the previous entry I explained how to setup a split power rail (and the reasons why you need one) to supply the + & - voltages used by the chip. Whilst not shown in this quick example, I used a TLE2426 rail splitter IC to supply +6V and -6V from a 12V power supply. I'll show the use of this chip in detail in another entry. Rather than go through the theory of the values used I've decided t
