Type:  I/O Module
Description:  SeaI/O-450 modules provide 16 channels of highly reliable SPDT Form C relay outputs rated for up to 60VDC @ 2A and connect to your host via Wireless 802.11b/g (Modbus TCP - 450W), Ethernet (Modbus TCP - 450E), USB (450U), RS232 (Modbus RTU - 450S), or RS485 (Modbus RTU - 450M). Each output offers normally open and normally closed contact connections via 3.5mm field removable terminal blocks. Communicate using industry standard Modbus RTU or Modbus TCP protocols or use the Sealevel SeaMAX software libraries from your application program. The SeaI/O-450 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.
