Binary IO module (BI, BO, and BIO)
Binary IO modules are provided in the IED to signal a command for external devices. Binary
IO modules are also used to receive status information. Binary IO modules are connected to
external devices with signal wires using terminal blocks on the rear of the IED. There are
standard type and variable type in Binary IO modules as shown in Table 5.4-1.

Note: PWS module supplies a DC voltage for binary IO modules: 48Vdc or 220Vdc.
Hence, the BIOs output circuits operate with the supplied DC voltage. Dual
voltages output (i.e., 48Vdc and 220Vdc) is not possible in the binary IO
modules.

Note: For details of the output circuits, see Table 5.4-8.

Note: For the binary input circuits in the standard type, the user can choice either
a high voltage or a low voltage with regard to the input threshold. For the
ones of the variable type, the user itself can set a threshold value with regard
to input voltage using settings.
