JAPMC-IO2301-E

What type of module is this?

It is a digital input/output option module for Yaskawa MP-series machine controllers. The module is designated LIO-02 and provides an interface between the controller and external digital devices.

What is the main function of this module?

The module receives digital status signals from field devices and sends digital control signals to connected loads. Typical applications include monitoring switches and sensors while controlling relays, indicators and other industrial devices.

How many digital input and output points does it provide?

The JAPMC-IO2301-E provides 16 digital inputs and 16 digital outputs, allowing multiple field signals to be connected through one option module.

What type of digital outputs does the module use?

As the LIO-02 version, it uses source-mode transistor outputs. This output arrangement should be matched carefully with the polarity and input characteristics of the connected equipment.

Does it include a pulse encoder input?

Yes. The module supports one pulse encoder input with A, B and Z-phase functions. The A and B phases use a 5 V differential input with a maximum frequency of 4 MHz, while the Z-phase photocoupler input supports a maximum frequency of 500 kHz.

Which controller platforms can accept this module?

Yaskawa documentation lists the module as an option card for MP2300Siec, MP2310iec, MP3200iec and MP3300iec controller systems. The available slot, base unit and overall system configuration should be checked before installation.

Which connection cable is used with the module?

The specified pigtail cable family for LIO-01 and LIO-02 modules is JEPMC-W2061. Listed cable lengths include 0.5 m, 1.0 m and 3.0 m versions.

Can the module detect an open output fuse?

Yes. The digital output section includes fuse-open detection. The internal fuses are intended for fire protection during output short circuits rather than complete circuit protection, so suitable external fuses should be selected for the connected loads.

Can the module be replaced while the controller remains powered?

No. Hot swapping is not supported. Power should be isolated before removing or installing the module, and the wiring and slot arrangement should be verified before the system is energised again.

What should be checked when replacing an existing unit?

Confirm the full model designation, LIO-02 type, source-output arrangement, connector wiring, external supply polarity, controller compatibility and cable type. Similar-looking Yaskawa LIO modules can have different output configurations and should not be treated as direct substitutes without verification.

What external supply is typically used for the digital I/O circuits?

The digital I/O circuits are designed around a 24 V DC field supply. Correct polarity is important, particularly for the source-mode outputs, as incorrect wiring can prevent loads from operating correctly or cause equipment damage.

What are common industrial uses for this module?

Common uses include reading limit switches, proximity sensors and machine status contacts, as well as operating interface relays, solenoid control circuits and indicator devices within coordinated machine-control systems.
