12 Jun 2003 16:09 Commercial PLCs' Schematic |
|
|
|
I need schematics of commercial PLCs' such as Siemens, OMRON.
Actually I am only interested in know about analog/digital input
and output stages and power supplies.
I need to feed my 5V circuit from 24V and I am looking for
a cost effective power supply schematic. The switching regulators
that I found (>500mA) cost at least 3$
