I am currently setting up a Nasty Labs Field Point as a test set to the 1771-IAD OAD and IXE mV cards in my PLC-5 chassis. My problem is that the OAD channels are reading 65 VAC to 73 VAC. I am wired 115 120 VAC to terms A_B_C_D and common to C at bottom, out channels to FP DI (discrete input) to common. The 65-73 is being read as an out by the FP DI thus lighting the psuedo (software lite), what I want to do is reduce the "strays" to below 14 V, I have already tried a shunt in parallel with the LOAD (FP DI) to no avail. I have also tried removing the OAD common and no joy again. Any tips on this Thanks guys Little Bob
