The micrologix 1100 - l16dwd supports 12 vdc. I was looking at adding a 1762-IQ16 to the 1100 but I am concerned that the module needs 24 vdc. The manual says voltage category 24 VDC but lists the Operating voltage range as 10-30 vdc. So which is it? has anyone used the 1762-IQ16 with a L16DWD in a 12 vdc system?
