Flexible and Reliable Solution for Industrial Control
The Selio 16-Relay Modbus I/O Module delivers robust performance and exceptional flexibility for industrial automation, data monitoring, and process control. Supporting Modbus RTU over RS485 and Modbus TCP/IP over Ethernet, this board ensures seamless communication with PLCs, HMIs, CPUs, and any equipment compatible with Modbus protocols.
Main Features
- 8 Opto-isolated Digital Inputs (AC/DC): Ideal for detecting signals from sensors, buttons, or switches, with enhanced immunity to electrical noise.
- 3 Analogue Inputs (8 or 12-bit): Suitable for acquiring data from analogue sensors and transducers.
- Temperature Sensor Support: Direct measurement of process or ambient temperature.
- 16 Relay Outputs: Reliable switching of loads, motors, valves, and other high-power devices.
- 3 Analogue Voltage Outputs (0-10V, ±10V): Flexible generation of analogue signals for industrial equipment.
- 1 Analogue Current Output (4-20mA): Standard current loop output for industrial control applications.
- Onboard Pressure Sensor: Integrated pressure monitoring for process and automation systems.
- Buzzer and LED Indicators: Immediate visual and audible status feedback for diagnostics and operation.
- DIP Switches for Modbus Register Assignment: Straightforward configuration of Modbus addresses directly on the module.
- Reset Button: Quick system reset, also accessible via Modbus command.
- Wide Input Voltage Range: Operates from 18VDC to 34VDC, with low standby consumption (120mA @ 24VDC).
Effortless Modbus Integration
The Selio 16-relay I/O module communicates via Modbus RTU (RS485) and Modbus TCP/IP (Ethernet), ensuring easy integration into existing industrial networks. Address assignment is managed directly on the board using DIP switches, simplifying installation and expansion.
Broad Compatibility
- PLCs: Works flawlessly with Siemens, Allen-Bradley, Schneider, and other leading brands.
- HMIs and CPUs: Integrates smoothly with SCADA and industrial control systems.
- Other Modbus Devices: Universal interfacing with any controller supporting Modbus RTU or Modbus TCP/IP.
