Contec Co., Ltd. (Headquarters: Nishiyodogawa-ku, Osaka; President: Kazuyoshi Nishiyama) has introduced two new ultra-compact and ultra-low power digital I/O units supporting Wi-Fi networks—the DIO-0404RY-LWF and the DIO-0404RY-LWF-US (for the U.S. market). Designed to accelerate IoT integration and wiring reduction in industrial applications, these new products will go on sale June 30, 2026.
DIO-0404RY-LWF
DIO-0404RY-LWF-US
The new products feature an ultra-compact, ultra-low power design that enables remote control and status monitoring of digital I/O signals via a Wi-Fi network. The products include 4 digital signal outputs (semiconductor relays) and 4 opto-coupler-isolated inputs (12–24 VDC, supporting both current sink and source outputs).
The units support Modbus-TCP communication over a Wi-Fi network. In addition, by using the API-DIO(WDM) driver library provided on the Contec website, users can develop application software in various programming languages such as Visual Basic and Visual C++.
These products make it easy to implement digital I/O control in equipment where installation space is limited and that requires low power consumption and high reliability, such as power control for battery-driven transport equipment or status monitoring for machinery operating in factories.
Main features
- Ultra-compact housing with internal antenna
The products feature a built-in antenna and an extremely compact size of 128(W) × 39(D) × 30(H) mm, allowing for installation inside equipment or in narrow spaces. They are ideal for retrofitting existing equipment or for system upgrades.
- Wiring-free operation via Wi-Fi 4 (IEEE 802.11n) 2.4/5 GHz stable wireless communication
The units support wireless LAN communication in both the 2.4 GHz and 5 GHz bands. This allows for the construction of a flexible and stable communication environment that accounts for radio interference without the need for cable wiring.
- Support for Modbus-TCP server
Modbus is a communication protocol that is widely used in industrial fields. These products enable remote control from higher-level devices with Modbus client functionality.
- Automatic low-voltage shutdown function
The units include an automatic low-voltage shutdown function that periodically monitors battery voltage via an internal A/D converter. If the voltage falls below a user-defined threshold, the internal semiconductor switch is automatically turned off to stop the product.
- Support for a wide range of temperatures
The products can be used in various environments with ambient temperatures of −20°C to +75°C.
- Wide-range power input
The units support a wide-range DC power supply of 5.5 to 60 VDC and achieve ultra-low power consumption, with an average current of 1.89 mA when operating at 12 VDC.*1
