General purpose PLC

Hi there,

Does anyone know where to find a small general purpose PLC or I/O-box with e.g 8 analog/digital inputs and 8 PWM outputs. It can be all small signals, or with some driver included. I don't know how such a PLC might be programmed, but perhaps it can be programmed by a Microchip ICD programmer.

I know the device is simple to construct from scratch, but this one has to be an off-the-shelf product for a different number of reasons.

it may be hard to find because standard small plc only have digital input/outputs (maybe 1-2 analog) and no pwm. Pwm is not used widely on industrial equipment.
also PLC are programmed via their own software generally.

How about a non-industrial product?

Could you use a PMW audio modulator such as one of these from TI?

No, the PLC is not for me, so it has to be fully operational with wire terminals for input and output. It may be hard to find such a product, that is both simple to program and not part of a complete industrial control system

You do not state where this device is to be used, but from what you have said it sounds as though a bought-in ready made device is required rather than something knocked up on a piece of veroboard!

I googled "brick plc" and one supplier that jumped out was Automation Direct, have a look at their website.

I guess that the DL05 or DL06 range of PLCs may do what you want, but whether to price will suit you, I dont know.
