Type:  I/O Module
Description:  SeaI/O-440 modules provide 32 SPST Form A dry contact Reed relays and connect to your host via Wireless 802.11b/g (Modbus TCP - 440W), Ethernet (Modbus TCP - 440E), USB (440U), RS232 (Modbus RTU - 440S), or RS485 (Modbus RTU - 440M). Reed relays offer long life performance and fast response time. Convenient removable 3.5mm screw terminals compatible with 16-30AWG wiring allow reliable connection to real-world I/O. Communicate using industry standard Modbus RTU or Modbus TCP protocols or use the Sealevel SeaMAX software libraries from your application program. The SeaI/O-440 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.
