HC-KFS43 MITSUBISHI Digital Input Module

Product  Description：

Mitsubishi Digital Input Modules are essential components in industrial automation, acting as the interface between external sensors and the central processing unit (CPU) of a Programmable Logic Controller (PLC). They convert physical signals from devices like buttons, limit switches, and proximity sensors into digital data for the PLC to process.

Product Overview

Mitsubishi Electric offers a diverse range of digital input modules across its major PLC series, including the MELSEC iQ-R, iQ-F (FX5), Q, and L series. These modules are designed to handle various voltage levels and connection types, ensuring compatibility with a wide array of field devices. Common types include DC input modules (typically 24V DC), AC input modules (100V to 240V AC), and specialized high-speed or safety-rated modules.

Product Parameters

The specific technical specifications vary depending on the model, but generally follow these industry standards:

Input Points Modules are available in densities of 8, 16, 32, or 64 points per module to accommodate different system sizes.

Rated Input Voltage The most common standard is 24V DC, though Mitsubishi also provides modules for 5V DC, 12V DC, 100-120V AC, and 200-240V AC.

Input Current Typical input current for a 24V DC point is approximately 4mA to 7mA.

Response Time Standard modules typically have a response time of 1ms to 10ms. High-speed modules can achieve response times as fast as 0.1ms or even 1μs in the iQ-R series.

Connection Type Options include screw terminal blocks for easy individual wiring, spring-clamp terminals for vibration resistance, and high-density connectors (40-pin) for 32/64 point modules.

Isolation Most modules utilize photo-coupler isolation to protect the internal PLC circuitry from external electrical surges or noise.

Product Advantages

High Reliability and Durability Built with industrial-grade components, these modules are designed for 24/7 operation in harsh environments, featuring excellent heat dissipation and noise immunity.

Space Efficiency High-density modules allow for up to 64 inputs in a very slim profile, significantly reducing the footprint required in control panels.

Flexible Wiring Options The availability of sink/source (plus/minus common) switching allows a single module type to be used with various sensor types, simplifying inventory and design.

Ease of Maintenance Equipped with status LEDs for every input point, users can perform quick visual troubleshooting to confirm whether signals are reaching the PLC without using a multi-meter.

Seamless Integration These modules are natively supported by Mitsubishi’s GX Works2 or GX Works3 software, allowing for automatic parameter configuration and easy diagnostic monitoring.

Precautions for Use

Wiring Accuracy Always ensure that the external power supply polarity matches the module’s sink or source configuration. Incorrect wiring can lead to short circuits or damage to the input circuitry.

Noise Prevention Keep input signal lines away from high-voltage power cables or motor drive lines. Use shielded cables if the module is operating in an electrically noisy environment to prevent "ghost" signals.

Voltage Limits Do not exceed the rated input voltage. Applying AC voltage to a DC input module will cause immediate and permanent failure.

Environment Control Ensure the operating temperature remains within the specified range (typically 0 to 55°C). Use cooling fans or heat exchangers in the cabinet if the ambient temperature is too high.

Live Plugging Never install or remove modules while the PLC power is on, as this may damage the internal bus interface or cause the CPU to crash.
