What is HUBBOX IOR4 Relay Controller?
HUBBOX IOR4 is a professional relay control module designed for industrial automation systems, operating over the Modbus TCP/IP protocol. It combines 4 high-current relay outputs and 4 digital inputs in a single compact device, providing an ideal solution for both monitoring field signals and controlling powerful actuators centrally.
Hardware and Capacity Features
- 4-Channel Relay Output (DO): High-capacity dry contact outputs capable of switching up to 5A @ 220VAC/30VDC. Suitable for direct control of contactors, valves, and motors.
- 4-Channel Digital Input (DI): Designed for monitoring limit switches, emergency stop buttons, and general signaling.
- Ethernet Interface: Provides high-speed 10/100 Mbps communication for real-time control.
- Industrial Design: Robust construction suitable for DIN Rail mounting, ensuring reliability in harsh environments.
- Status Indicators: Individual LED indicators for each input and output channel for easy on-site troubleshooting.
Modbus Poll Connection Guide
To control the relays or monitor the inputs using Modbus Poll software, follow these configuration steps:
Default Connection Parameters:
• IP Address:
• Subnet Mask:
• TCP Port:
• IP Address:
192.168.24.251• Subnet Mask:
255.255.255.0• TCP Port:
502Step-by-Step Connection
- Open Modbus Poll and go to "Connection > Connect".
- Select "Modbus TCP/IP".
- Enter the default IP address:
192.168.24.251and port502. - Once connected, configure the registers via "Setup > Read/Write Definition".
Essential Register Address Table
| Data Type | Address Range | Description | Access |
|---|---|---|---|
| Coils (01) | 1 - 4 | Relay Outputs (Out1 - Out4) | Read/Write |
| Discrete Inputs (02) | 10001 - 10004 | Digital Input Status (Input1 - Input4) | Read Only |
| Holding Registers (03) | 40004 - 40007 | Device IP Configuration (Octets) | Read/Write |
| Holding Registers (03) | 40008 - 40011 | Subnet Mask Configuration | Read/Write |
Technical Support and Maintenance
Safety Tip: The relay outputs are rated for 5A. For high-power inductive loads like large motors or heaters, it is highly recommended to use an external contactor to protect the device's internal relays.
- Factory Reset: Use the physical reset button on the device to restore default network settings if communication is lost.
- Simultaneous Connections: The IOR4 supports up to 2 concurrent Modbus TCP connections, allowing simultaneous access from both a PLC and a monitoring software.
- Power Requirements: Ensure a stable power feed within the 12-35 VDC / 3A range.
