The SeaI/O-430M offers a reliable and scalable solution to interface 32 optically isolated inputs over any RS-485 Modbus RTU connection. Ideal for monitoring industrial signals, its inputs operate from 5–30VDC with 300V external isolation protection. The module features grouped 4-bit segments for simplified wiring, with each group sharing a common terminal.
Use it with the standard Modbus RTU protocol or integrate easily into applications with Sealevel’s SeaMAX API libraries. It supports Windows and Linux systems for seamless deployment. The unit is powered via 9–30VDC and comes with pass-through connectors, allowing expansion with up to 246 additional SeaI/O modules such as Reed relays, TTL I/O, analog input/output, and more.
With a rugged enclosure, this product is ready for demanding industrial environments. It also pairs well with Sealevel’s digital I/O handbook for quick development.
