One Relay Platform. More Ways to Automate. Built to Scale With Your Application.
Need to switch equipment, automate a test sequence, control power remotely, or integrate relays into your software?
LEO makes it simple.
The LEO Relay Series combines relay outputs, digital inputs, automation features, and flexible connectivity in compact, ready-to-use modules – giving you a practical way to move from a simple switching requirement to a complete automation system.
What can you achieve with LEO?
- Automated test systems – power cycling, sequence control, and equipment switching
- Industrial automation – control machines, actuators, contactors, and other equipment
- Remote switching – control equipment over Ethernet or Wi-Fi
- Laboratory automation – automate instruments, pumps, power supplies, and processes
- Equipment control – add reliable relay control without designing your own relay hardware
- Production systems – automate repetitive switching and testing operations
Choose the Control You Need
LEO CR8 – USB Relay Series
Direct PC & Embedded control
Connect directly to your PC or embedded system through USB.
With USB CDC/serial communication, command-line control, and language-agnostic integration, CR8 makes it easy to integrate relay control into your existing software and automation setup.
Ideal for:
PC-based automation • Test systems • Laboratory setups • Equipment control • Embedded applications
LEO WR8 – Network Relay Series
Networked & Remote Control
When your relay system needs to be accessible over a network, WR8 provides Ethernet and 2.4 GHz Wi-Fi connectivity.
With Web Server, REST API, Telnet, MQTT/MQTTS, and USB configuration, WR8 gives you multiple ways to integrate, configure, monitor, and control your equipment.
Ideal for:
Industrial automation • Remote switching • Distributed systems • IoT applications • Networked test systems
The LEO Advantage
Don’t Just Buy a Relay. Get the Control System Around It.
With LEO, you get more than relay outputs.
Relay Control + Digital Inputs + Connectivity + Automation + Software Interfaces
All in one ready-to-deploy platform.
That means less time designing supporting hardware and more time building your actual application.
Built to Grow With Your Application
The LEO Series starts with 8-channel relay modules designed to give you a powerful, ready-to-integrate control solution from day one.
As your application and channel requirements grow, the LEO family will continue to expand with new relay configurations and variants.
Start with 8. Scale as You Grow.
Choose the LEO configuration that fits your application today — with more channel options and configurations coming to the LEO Series.
One platform. Multiple channel options. Multiple connectivity options. Built for automation. No need to redesign your control architecture from scratch.
