Hello All: This may be a repeat post - I looked at my history and did not see it. I am looking for a product ( finished/qualified) that takes a standard Analog signal ( 0-10V and/or 4-20mA) and converts to a PWM signal with fixed but settable; Frequency of ~ 100 to 5000hZ - possibly with a dip switch. For example - if using the 0-10V input - at 5V the PWM signal has DS of 50%. Needs to be hardwired - not a programmable device. In some circles this would be considered a signal conditioner.
