Description
The M240-Remote I/O Module is a cutting-edge signal conditioner designed for robust performance in industrial applications. This 4-channel discrete input module features RS485 communication, providing essential isolation between each channel of inputs, power, and network circuits. Adhering to the industry-standard RS-485 Modbus RTU protocol, the module supports both AC and DC power sources with nonpolarized, diode-coupled terminals. It functions not only as an independent signal isolator with communication capabilities but can also be combined with the MWG1 to form a comprehensive remote I/O Data Acquisition System (DAS) that supports both MODBUS RTU and MODBUS TCP protocols.
Features
- Substitution Capability: Replaces the analog isolator with a communication isolator.
- Six-way Isolation: Prevents potential ground loops among power, input, output, and network circuitry.
- Hot Swappable: Allows for easy replacement without system downtime.
- Redundant Power: Features terminal block and rail bus for power redundancy.
- High-speed Communication: Standard Modbus RTU protocol supports RS-485 communication speeds of up to 115K bps.
- Modular Compatibility: Works with MWG1 for remote I/O DAS, supporting both MODBUS RTU and MODBUS TCP.
