The SeaI/O-520U-OEM is a USB-based device that allows control and monitoring of 8 optically isolated inputs and 8 high-current SPDT Form C relay outputs. It's perfect for applications requiring reliable digital I/O and high-current relay control, using the Modbus RTU protocol..

  • Detail
  • Special Features
  • Specification

The SeaI/O-520U-OEM provides a compact solution for digital control and monitoring. The 8 optically isolated inputs ensure that sensitive equipment is protected from electrical noise and transients. The 8 Form C relays are ideal for controlling high-current devices, such as motors or large control systems, and can be used in either normally open or normally closed configurations.

This device uses USB communication and Modbus RTU for easy integration with industrial control systems. With its removable screw terminals, field wiring becomes hassle-free. The SeaLATCH USB port guarantees a secure connection, eliminating any risk of accidental disconnection.

  • 8 Optically Isolated Inputs – Provides 300V isolation from external equipment, preventing damage from voltage spikes and ground loops.

  • 8 High-Current Form C Relays – Can handle up to 6A at 250VAC or 5A at 30VDC, ideal for switching large loads.

  • Form C Relays – Can be wired for normally open (NO) or normally closed (NC) operation.

  • USB Connectivity – Easy USB connection for seamless data communication.

  • Power Range – 9-30VDC powering options, compatible with Sealevel’s power supply solutions.

  • Modbus RTU Protocol – Use with industry-standard Modbus RTU protocol, integrating easily with Windows and Linux systems.

  • Removable Screw Terminals – Simplifies field wiring and installation.

  • SeaLATCH Locking USB Port – Provides a secure connection using SeaLATCH USB cables to prevent accidental disconnections.

  • DIN Rail or Table Mountable – Flexible installation options.
