|Touchscreen Appliance Energy Meter PCB [04116061 RevG] plus adaptor board|
Main PCB for the Touchscreen-controlled Energy Meter. A Micromite LCD BackPack kit is also required.
Double-sided PCB with plated through holes, solder mask and silkscreen overlay.
Note that pins 23, 24, 25 & 26 of CON9 are supposed to be joined together but corruption of the PCB file has resulted in some production boards missing these tracks. In this case, only pin 23 is connected to IC2. In this case, shorting pins 23 and 25 of CON9 should solve the problem. Eventually, RevH boards will be made available which solves this problem.
Also, we are supplying this PCB with an adaptor board that allows an ACS718 IC to be used rather than the ACS712 originally specified. This is important as the ACS712 does not have a sufficient Reinforced Voltage Rating to be used in double-insulated equipment. As such, this PCB has been discounted. You will need to delete one 100nF SMD capacitor from the parts list, add the ACS718 and a 1nF SMD capacitor, plus a short length of tinned copper wire and some light duty hookup wire or Kynar. Details on the changes required will be published in the December 2016 issue.
