2-ch 2Amp or 5Amp* Relays, 2-ch Digital Inputs, Ethernet Controlled Module Introduction The IA-3721-EM is an Industrial Ethernet Remote I/O Module, with 2 Relay channels and 2 Digital or Counters Input channels, in an Open Frame format. The Ethernet port is based on a 32-bit Freescale ColdFire Processor, providing 10/100baseT interface, supporting TCP and UDP with DHCP or Static IP mode. The Digital Inputs includes Programmable Digital Filter and may be used as 32bit counters as well. They accept positive and negative Logic, as well as Dry-contact or Wet signal input. Both relays have a 2Amp @ 30VDC contact rating. One A Form and one C Form type. The software support package includes Web Page Configuration tool, Dot.net library and open code examples. 2-ch Relay, SPDT and SPST 2-ch Digital/Counter Input Small Footprint 85x50mm 32-bit, 3 KHz Counters Software Selected Digital Input Logic Peer-to-Peer operation ready Wide Supply Range 10 to 30VDC Wide software package Selectable Input pull-ups source Din-Rail mounting option 2-ch 2Amp Relays, 2-ch Digital Inputs, RJ-45, Lan Cable, 1m included Ethernet Controlled Module 2-ch 5Amp Relays, 2-ch Digital Inputs, RJ-45, Lan Cable, 1m included Ethernet Controlled Module Relay Channels Contact Format Contact Rating Operation Time Release Time 2 Form C, Form A 2Amp @ 30VDC 5Amp Optional 7mS max. 4mS max.
