The SeaI/O-440E-OEM is a board-only Ethernet output module featuring 32 SPST Form A Reed relays. Designed for embedded and OEM applications, it offers Modbus TCP communication and reliable switching for low-voltage automation and control systems..
The SeaI/O-440E-OEM offers 32 Form A Reed relay outputs in a compact board-only form factor for OEM integration. Each SPST relay provides dry contact switching rated for 60VDC at 500mA, making this unit ideal for controlling LEDs, indicators, alarms, or low-voltage actuators in industrial or automation environments.
The device connects via 10/100BaseT Ethernet and communicates using Modbus TCP, allowing direct integration with SCADA systems, PLCs, or control software. It also supports Sealevel’s SeaMAX API, enabling developers to create custom applications on both Windows and Linux platforms.
With removable 3.5mm screw terminals, the 440E-OEM ensures efficient field wiring and maintenance. It accepts 9–30VDC power, providing flexibility in various installations. This board-only design is perfect for tight enclosures, custom panels, or embedded control systems.
Need to expand? The SeaI/O-440E-OEM supports up to 246 additional SeaI/O modules, allowing future scalability. Plus, with the Sealevel Modbus Connect iOS app, users can monitor or test relay status remotely from the field.
