7.2 UIO-37 Screw Terminal Block
The UIO-37 Screw Terminal Block shown in Figure 7-2 connects directly to the optional CP-1037 cable assembly to provide users with a screw terminal interface. The D37 connector of the CP-1037 connects directly to the 37 screw terminal blocks of the UIO-37. Each screw terminal is numbered for easy reference.
NOTE:
Since only the first 31 connections on the IOP-241 are available on the CP-1037 cable assembly, two of the IOP-241's ground connections (pins 32 and 33) are not available when using the UIO-37.
