I'm working on a project on a SLC 500 PLC. I have order 2 DC modules and they are 1746-IV8 and 1746-OV8. I have tested the +24VDC on the power supply on the PLC and reads 22.9V and after wiring the new modules the Voltage reads 1.5 volts. I'm wondering if the wiring is wrong or the new modules were bad.
