For more information about the specifications of A2EXR001, refer to :I/O Adaptors (for N-IO)
(GS 33J62F30-01EN)
The shunt resistor unit (Model: A2EXR001) 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.
Structure and parts of the shunt resistor unit
The shunt resistor unit has terminal blocks with either pressure clamp terminals or spring clamp
terminals.
The following figure shows the structure and parts of the shunt resistor unit, using an example of
the model with pressure clamp terminal-type terminal blocks.

Figure Shunt resistor unit
The shunt resistor unit has terminal blocks for channel numbers 1 to 4. Each terminal block is
provided with two slots that are used to install a shunt resistor module or a short plug. Short plugs
are installed on these slots when the unit is shipped from the factory. The shunt resistor modules
are accessories.
