KEYENCE IV4-G120 AI Vision Sensor Amplifier

IV4-G120 Controller | Keyence IV4 Series

Product Introduction

The IV4-G120 from Keyence belongs to the IV4 Series of compact sensor amplifiers. As a controller unit, it pairs with IV4-G series sensor heads to form a complete AI vision system. Moreover, the device suits space-constrained control cabinets through its DIN-rail mounting design.

Additionally, this amplifier supports three operational modes: Standard Mode, Sorting Mode, and AI Through Count Mode. Each mode targets distinct inspection tasks, from presence verification to complex sorting. Consequently, one hardware unit covers diverse machine vision applications.

Technical Specifications

Vision Tools and Modes

The IV4-G120 provides 65 tools for image processing. In Standard and Sorting Modes, available tools include AI Differentiate, Outline, Color Area, Edge Pixels, Width, Diameter, Blob Count, AI OCR, and AI Count. Meanwhile, AI Through Count Mode offers Count and Total functions for high-speed passing inspection.

Programs and Image Management

Users can store 128 programs with an SD card, or 32 programs without one. Furthermore, the image history function retains up to 100 images. Image data transfers to microSD, FTP, or SFTP destinations in BMP, JPEG, or text formats.

Communication and Networking

A built-in RJ45 connector supports 1000BASE-T and 100BASE-TX Ethernet. Additionally, the controller offers EtherNet/IP, PROFINET CC-B, TCP/IP, FTP client, SFTP client, SNTP client, OPC UA server, and MQTT client protocols. For expanded fieldbus options, IV4-GCU1 adds PROFINET CC-C and EtherCAT.

Electrical and I/O Specifications

The IV4-G120 operates on 24 VDC with +25%/-20% tolerance. Power draw reaches 2.2 A at 19.2 V or 1.7 A at 24.0 V, excluding illumination and communication units. The controller provides 8 inputs (IN1–IN8) and 8 open-collector outputs (OUT1–OUT8). Output type switches between NPN and PNP, with N.O./N.C. selectable.

Mechanical and Environmental Parameters

Physical Construction

The main unit case uses PC material, while the rear heat sink is aluminum. Connector materials vary by function: the power supply connector uses PA, the I/O connector uses LCP, and the sensor head connector combines zinc with nickel plating and PA. The Ethernet connector uses copper alloy with gold plating.

Environmental Limits

Operating temperature ranges from 0 to +50°C without freezing. Relative humidity must stay at 85% RH or below, with no condensation. Notably, the product carries no specific protection rating. Therefore, install it in a clean, dry control panel environment.

Installation Guide

First, mount the IV4-G120 onto a standard DIN-rail inside the control cabinet. Ensure adequate clearance around the rear heat sink for thermal dissipation. Next, connect the sensor head using the dedicated connector, then wire the 24 VDC power supply. Subsequently, attach Ethernet and I/O cables to the respective ports.

After power-on, configure the IP address and select the appropriate protocol through the setup menu. For stable operation, verify that the supply voltage stays within the specified tolerance range. Finally, run the built-in simulator or test mode to validate tool settings before production.

FAQ

Q1: What is the difference between the IV4-G120 and other IV4 controllers?
A: The IV4-G120 is the compact DIN-rail amplifier for IV4-G series heads. Other models like the IV4-G500CA integrate the camera and amplifier into one unit.

Q2: Does this controller support OPC UA?
A: Yes. It functions as an OPC UA server, enabling direct data exchange with SCADA and MES systems without middleware.

Q3: How many programs can I store without an SD card?
A: Without a card, the controller holds 32 programs. With a microSD card installed, that capacity rises to 128 programs.

Q4: What shipping methods do you offer?
A: We ship via Fedex, UPS, and DHL. Transit times vary by destination, typically 3–7 business days.

Q5: Can I use this with an Allen-Bradley PLC?
A: Yes. The EtherNet/IP protocol allows direct communication with Allen-Bradley CompactLogix and ControlLogix controllers.
