English 420W SeaI/O-420W Expansion Module Wi-Fi 802.11b/g Modbus TCP Interface to 16 Isolated Inputs / 8 Form C Relay Output
Description
Control and monitor 16 optically isolated inputs and 8 Form C (SPDT) relay outputs over a wireless network with the SeaI/O-420W. Inputs can range from 5-30VDC, while the Form C relays provide switch closures up to 60VDC @ 2A. Inputs and outputs are grouped into four-bit segments that each share a common for easy wiring via removable 3.5mm terminal blocks. The SeaI/O-420W is powered from your 9-30VDC source, or select from a variety of Sealevel power supply options.
Communicate with the SeaI/O-420W over Wi-Fi (802.11b and 802.11g) networks using the Sealevel SeaMAX API software libraries or use any Modbus TCP compliant device. Sealevel’s SeaMAX software drivers and utilities make installation and operation easy using Microsoft Windows and Linux operating systems. Security features include WEP and the latest WPA-TKIP and WPA2-AES encryption standards.
The Sealevel Modbus Connect app for iOS allows you to access the registers, coils and discrete I/O of your Sealevel Modbus devices and is available on the App Store. Use the app to remotely access I/O in the field or for testing and troubleshooting during application development.
Expand your I/O network with SeaI/O N-series products. SeaI/O modules are available with Reed and Form C relays, optically isolated inputs, TTL interfaces, A/D and D/A functionality. Up to 246 additional expansion modules can be added using convenient pass-through connectors.
