Combine Relay Control and Modbus Capabilities
- Works with the Radius BZ1 Area Monitor
- Local monitoring options to better automate hazard awareness across the entire site
- Increased prioritization of needs and risks
- Effective communication when hazards are present
- Actionable, long-term safety response protocols

Take Your Area Monitoring Solutions to the Next Level
By combining relay control and Modbus capabilities with the Radius BZ1 Area Monitor, you can:
- Connect and power up to eight external devices – including light bars, sirens, and ventilation, with relay control
- Integrate with your internal systems through Modbus
- Design a system that focuses on multiple hazards at once, so you don’t have to pick and choose between priority hazards
- View data from multiple locations on the same site with Modbus, and multiple sites remotely thanks to iNet Now
This means a proper safety response is initiated automatically based on the hazard present. Plus, it’s easier than ever to automate your safety response protocols so safety managers, no matter their location, know there’s a hazard and how to respond.

The Radius BZ1 is a rugged, portable area monitor that's always working, even when you're not. This area monitor can be deployed for up to 50 days in the world's harshest environments and features actionable alarms that can cut through even the busiest work areas.

When it comes to protecting your worksite from hazardous gases, you need the best area monitor.
No other area monitor protects your workers with less setup, user training, and time in the shop than the Radius BZ1. See how the Radius BZ1 area monitor protects your workers longer in the field with less setup, user training, and time in the shop.

What is Relay Control and Why Would I Need One in My Gas Detection Setup?
Relay control setups have many different applications, but when it comes to gas detection, they’re critical in helping to improve safety protocols and taking setup times from days to hours.
Incorporating a relay control operation can enable more flexible deployments of the Radius BZ1 Area Monitor, as well as additional safety protocols to be added to a user’s personal monitoring set up, by sending out a signal to the appropriate controls – such as light bars, sirens, and ventilation – where the relay can switch from “off” to “on” to trigger safety protocols.
Combined with your area monitoring setup, it’s easier than ever to automate your safety response protocols so safety managers, no matter their location, know there’s a hazard and how to respond.
Relay control setups have many different applications, but when it comes to gas detection in the upstream oil and gas industry, for example, they’re critical in helping to improve safety protocols and vastly reducing setup times.
What is Modbus and Why Would I Need One in My Gas Detection Setup?
The Radius BZ1 also supports Modbus capabilities, but what does that mean for your gas detection program?
Think of the RGX like a central communications hub at your company. It collects and compiles data from each department (like device and sensor data) then formats it into a standardized report (using Modbus). From there, it’s automatically distributed to relevant departments (through your control systems).
This simple setup enables everyone in your company to have a complete picture of what’s happening across departments. So when it comes to gas detection, Modbus provides sitewide visibility and advanced decision logic by sharing gas detection data between different devices and control systems to ensure the proper response is kicked off.
With Modbus, you can:
