Can the 4-20mA expansion module run on 12V?

I've chosen a Logo! 12/24RCEO (6ED1052-2MD08-0BA1) as the main controller, which supports 12 to 24V DC. I need two 4-20mA outputs so I've included an AM2 AQ (6ED1055-1MM00-0BA2). Can I run the AM2 AQ on the same 12V power? The datasheet for it shows as 24V. I don't want another PSU in the system... Cheers Mark
