The SeaI/O-420E-OEM is a compact, board-only Ethernet I/O module engineered for integration into custom systems, panels, and industrial enclosures. It delivers reliable remote control of 16 optically isolated inputs and 8 Form C relays over standard 10/100BaseT Ethernet using Modbus TCP or Sealevel’s SeaMAX API.
The isolated inputs accept 5–30VDC, providing robust protection from voltage spikes, ground loops, and electrical noise. The SPDT Form C relays offer versatile control over low-voltage loads up to 60VDC at 2A—perfect for alarms, indicators, or control relays.
The board is powered via a 9–30VDC input and is designed to support OEM applications where space, flexibility, and direct integration are critical. It features removable 3.5mm terminal blocks for efficient, modular wiring.
Expand your control capabilities by chaining up to 246 SeaI/O N-series modules through the unit’s pass-through connectors. And for real-time testing or remote diagnostics, the Sealevel Modbus Connect iOS app allows register and coil access in the field.
