R-4AO-8DIDO

R-4AO-8DIDO-2

Ethernet module with 4 analog outputs and 8 digital inputs/outputs

The R-4AO-8DIDO mixed digital module is equipped with two 10/100 Mbps Ethernet ports, supporting both ModBUS TCP-IP communication and RS485 serial communication with the ModBUS RTU protocol. Like all R Series models, it is designed to meet the needs of flexible wiring, limited installation space and high I/O-density applications with integrated Ethernet networking.

R-4AO-8DIDO offers 4 analog outputs and 8 digital channels, each individually configurable as a digital input or output. Configuration is performed through a web server with HTML5 support or via DIP switches. The IP address, MAC address and firmware version associated with the module can be identified or configured on the LAN using the SDD (Seneca Discovery Device) tool.

The module can be connected in Ethernet daisy-chain mode with fault bypass to ensure Ethernet connectivity even if a module in the chain fails. The device also features the advanced "ModBUS Passthrough" function, which allows the module to redirect requests from Modbus TCP-IP to RS485, effectively acting as a gateway.
