Binary input (BI) feature in BI1A and BIO5A
4.4.1
Binary input circuits have common programmable logic (CPL). Several circuits are
independent, but the others are not independent, as shown in Table 4.4-2.

-Applied in BIO5 only
The user can find the connector of binary IO modules, the terminal number and
arrangement of the binary input circuits in section 4.4.5.
Binary input (BI) circuit
4.4.2
The binary input circuit has a threshold for the input voltage and the user can regulate the
threshold using scheme switches and settings. Additionally, the binary input circuit has a
function in response to chattering signals produced by bouncing contacts, a programmable logic
for retarding and inverting the signal, and the user can set the respective features with
