Designed using the Maxim MAX197 successive approximation-type A/D chip, the SeaI/O-470M-OEM is an RS-485 Modbus RTU interface providing 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 inputs feature 5MHz bandwidth track/hold and 100ksps throughput rate. The two 12-bit D/A channels are jumper selectable for 0-5V and 0-10V output ranges.
Additionally, the SeaI/O-470M-OEM module provides eight optically isolated inputs rated for 5-30VDC 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-470M-OEM includes removable screw terminals, which simplify field-wiring connections. The SeaI/O-470M-OEM is powered from your 9-30VDC source, or select from a variety of Sealevel power supply options.
Communicate with the SeaI/O-470M-OEM using the Sealevel SeaMAX API software libraries or use any Modbus RTU compliant device. Sealevel's SeaMAX software drivers and utilities make installation and operation easy using Windows 2000/XP. SeaMAX now supports the Windows Vista operating system. Download the updated driver below.
Expand your I/O network with SeaI/O "N" series products. SeaI/O OEM boards 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.
