Using the Maxim MAX197 successive approximation-type A/D chip, the SeaI/O-470W provides a wireless network connection to eight differential or 16 single-ended 12-bit inputs and two 12-bit D/A output channels. The A/D inputs are software selectable for 0-5V, 0-10V, +/-5V, and +/-10V ranges and each channel can be configured via hardware for measuring 4-20mA current loop. The two 12-bit D/A channels are jumper selectable for 0-5V and 0-10V output ranges.

Additionally, the SeaI/O-470W module provides eight optically isolated inputs rated for 5-30V DC and feature 300V external isolation, while eight open collector outputs can sink up to 580mA - ideal for switching 24V devices commonly found in industrial environments. Perfect for a variety of data acquisition/control and test & measurement applications, the SeaI/O-470W includes removable screw terminals, which simplify field-wiring connections. The SeaI/O-470W is powered from your 9-30V DC source, or select from a variety of Sealevel power supply options.

Communicate with the SeaI/O-470W over 802.11b and 802.11g wireless networks using industry standard Modbus TCP protocol or use the Sealevel SeaMAX API software libraries from your application program. Security features include WEP and the latest WPA-TKIP and WPA2-AES encryption standards.

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.
