Hello everyone,
I calculated and MOV for this PLC ,which I will supply with 208VAC and it produces 24VDC output which I will use for sensors inputs.
Voltage:
Maximum allowed voltage 264VAC / 0.707 = 373VAC (Rounded)
Current:
In the data sheet there's Current consumption, max. 150 mA at 240 V AC and in the manual there's
Input current (max. load) 40 mA at 240 V AC and Output current rating (max.) 300 mA (shortcircuit protected).
Which I find confusing. If the CPU consumes 40mA at VAC and the maximum output current rating is 300 mA then I should rate my MOV at twice the total of 300+40 = 680 mA.
or does the Current Consumption, max of 150 mA means that the CPU may at times need 150 mA and that I should calculate my rating at twice 150 + 300 = 900 mA?
Either way I couldn't find MOV with that little current rating but I would like to know what these ratings mean,
Thanks
