The SeaI/O-410U-OEM offers 16 optically isolated inputs and 16 Reed relay outputs for industrial control and monitoring via USB. It uses Modbus RTU protocol for easy integration into control systems and provides long-life relay outputs for low-current devices..
The SeaI/O-410U-OEM is a USB-based I/O module that features 16 optically isolated inputs and 16 Reed relay outputs, designed for industrial control and monitoring applications. The optically isolated inputs are ideal for safely interfacing with external devices operating at high voltages, with input ranges of 5-30VDC.
The Reed relays provide long-lasting, low-current switching, perfect for controlling devices such as sensors, actuators, and other low-power equipment. These relays are configurable for normally open or normally closed operation, offering flexibility for various control requirements.
Communication is done using the Modbus RTU protocol over USB, which allows easy connection to computers or other control systems. The SeaI/O-410U-OEM is powered by a 9-30VDC source, and its removable screw terminals make it easy to wire and install in the field.
For system expansion, the SeaI/O-410U-OEM can support up to 246 additional SeaI/O N-series modules, making it scalable for large, distributed control systems.
