A2SAP105 Pulse Input Signal Adaptor
When the pulse input signal adaptor is used, signal connections to the base plate and shunt
resistor usage depend on the type of the pulse signal that is input. When receiving dry contact
signals, you can remove mechanical chattering noise by selecting the pulse input filtering option
in the IOM builder. However, the input filter passes a limited range of frequencies.
When connecting the field signal via the terminal board (A2BM4), the terminal-A, B, and C can be
used for the following circuit diagrams but the terminal-D cannot be used.

Select “Without Shunt Resistor” (SW1: OFF) in the IOM builder.
The following figure shows the circuit diagram.
