Dear Colleague,

We would like to use above model for 8 RTDs as 3-Wire Connection but we are having hard time to find exact pin number of this card.

My assumption of pin number can be bellows;

CH0 : 1,2,3,4 / CH1:5,6,7,8 / CH2:9,10,11,12 / CH3:13,14,15,16

CH4 : 21,22,23,24 / CH5:25,26,27,28 / CH6: / 29,30,31,32 / CH7:33,34,35,36

CH8 : 37,38,39,40

also I think CH8 would be reference channel but I can't find detail information of it on the manuals

Please give me information

Thanks
