The SeaI/O-420W allows seamless integration of 16 optically isolated inputs and 8 Form C relay outputs into your wireless Modbus TCP network. It provides a secure connection using Wi-Fi (802.11b/g) and supports modern encryption standards like WPA2-AES. The Reed relays offer fast switching capabilities for low current devices, while the optically isolated inputs protect your system from electrical transients. This module is fully compatible with Sealevel's SeaMAX API, allowing easy software integration. Additionally, you can use the Sealevel Modbus Connect app for iOS to monitor and control I/O remotely.
