When receiving dry contact signals (Input frequency: 0 to 10 kHz)
Select "Without Shunt Resistor" (SW1: OFF) in the IOM builder. Also install two 510 Ω shunt
resistor modules on the shunt resistor unit. The total resistance value will be 1.02 kΩ.
The following figure shows the circuit diagram.

(GS 33J64F10-01EN)
The shunt resistor unit (Model: A2EXR001-S000030/KFR) converts the current signals of the
internal circuit of the pulse input signal adaptor into voltage signals and is capable of converting
four points of signals. It is used when receiving dry contact signal inputs with 0 to 10 kHz input
frequencies or current pulse signal inputs.
