Type:  I/O Module
Description:  SeaI/O-430 modules offer 32 optically isolated inputs with 300V external isolation and high channel-to-channel isolation. Connect to your host via Wireless 802.11b/g (Modbus TCP - 430W), Ethernet (Modbus TCP - 430E), USB (430U), RS232 (Modbus RTU - 430S), or RS485 (Modbus RTU - 430M). Ideal for low voltage monitoring applications, connection to real world signals is made via convenient 3.5mm removable screw terminal connectors. Communicate using industry standard Modbus/RTU or Modbus/TCP protocols or use the Sealevel SeaMAX software libraries from your application program. The SeaI/O-430 module is powered from your 9-30VDC source, or select from a variety of power supply options. Up to 246 additional modules can be added using convenient pass-through connectors.
