The SeaI/O-430M-OEM is an RS-485 Modbus RTU-based I/O module that allows interfacing with 32 optically isolated digital inputs. Ideal for OEM applications, it offers wide voltage input support and robust 300V external isolation for industrial-grade performance..
The SeaI/O-430M-OEM enables seamless integration of 32 digital inputs into any RS-485 Modbus RTU network. Inputs are grouped into 4-bit segments, each sharing a common ground, and can handle a wide voltage range of 5–30VDC. Designed for industrial environments, each input provides 300V of isolation from external signals, ensuring safety and stability.
Connectivity is established through 3.5mm removable screw terminals, making wiring quick and reliable. Power the board with a 9–30VDC input, or choose from Sealevel’s available power supply options.
Software integration is straightforward using the industry-standard Modbus RTU protocol or Sealevel’s SeaMAX API software libraries. Compatible with both Windows and Linux systems, the included SeaMAX drivers simplify deployment and operation.
Expand your control system with SeaI/O N-series products, supporting relays, analog I/O, and TTL interfaces. Up to 246 modules can be daisy-chained for large-scale deployments.
