3 PT100(2 wires) connected to module SM1231 - 3 PT100 seems to be in parallel condition.

 Hi Pegaia,

I got a unusual issue, after I connected 3 PT100(2 wires) to shis module SM1231, it seems the 3 PT100 have been in parallel condition. Is there any short jumper inside this module? Like all the M- and I- are in  the small  connection inside?
