Digital I/O module IA-2128-E

Ethernet TCP/IPvoltage8-channel

The IA-2128-E is a TCP/IP/Ethernet I/O module with 16 Digital Input channels, 2 Digital I/O channels and 8 Photo Relays. This compact I/O device includes a wide variety of operation modes. Monitoring the Digital Input states can be handled both by Polling and by sensing state changes, generating an Auto Report on each state change. Additional feature is selecting the Auto Report transferring channel between the main channels to an additional dedicated one. Another operation mode is a Peer-to-Peer one. This operation mode enables a two-way state reflection between two modules of the same kind, in a direct way without the need for a host computer. Another feature is setting the Digital Input structure as Pull-up or Pull-down one, setting the Input Logic accordingly, Extra dual, Digital I/O channels, are built of open collector and pull-up resistors providing a rich widening option that might be used for Handshaking, Synchronization, Communication, etc. The Photo Relays are Isolated Solid State relays with an excellent performance, providing the ability of using them both as Relays and as a Multifunction Output stage. It can easily function as a PNP or NPN Open Collector output stage, by simply connecting them either to GND or Positive Voltage.
