DC block input modules are compatible with 1771 series output modules if

the off-state leakage current of the module is less than the block module

minimum off-state current and the on-state voltage minimum of the dc

block input is greater than the supply voltage minus the on-state voltage

drop across the 1771 output module. Some 1771 I/O modules that meet

these specifications are:

1771-OB dc output driver module

1771-OBD dc (10–60V) output module

1771-OBN dc (10–30V) output module

Other Allen-Bradley products that are compatible with block inputs are

shown in Table 2.A.
