The SeaI/O-462M-OEM is an RS-485 Modbus RTU interface board offering 96 buffered TTL I/O channels via dual DB-78 connectors. It is designed for industrial control, allowing easy connection to solid-state relay racks and seamless integration with Windows and Linux systems using SeaMAX software..
The SeaI/O-462M-OEM provides 96 digital I/O channels through an RS-485 Modbus RTU interface, making it ideal for PC-based industrial automation tasks. The 96 I/O lines are grouped into twelve 8-bit ports, each configurable as input or output. Designed for OEM use, it comes as a board-only solution with mounting standoffs and offers flexible power input through either a terminal block or modular connector.
Connection to standard relay racks is straightforward with Sealevel’s CA237 cable, which splits the DB-78 connector into two 50-pin IDC connectors. Communication is enabled using the Modbus RTU protocol or Sealevel’s SeaMAX API for custom development. Compatible with both Windows and Linux, this product is a robust choice for scalable digital I/O applications.
Whether you're managing industrial sensors, automation controls, or building an expandable relay system, the SeaI/O-462M-OEM provides a flexible and cost-effective foundation.
