Opto22

E1 and E2 Brain Boards

Type:  I/O Interface
Description:  E1 and E2 brain boards are Ethernet-ready I/O and communication processors for digital and analog I/O systems. The E1 connects to a rack of Opto 22 G1, G4, or Quad Pak™ digital I/O modules, while the E2 connects to a rack of Opto 22 G1 analog I/O modules. Each brain board communicates with a host computer and performs control functions for each I/O point.
Connectivity:  Modbus TCP
Features:  Drop-in replacement for existing B1 and B2 brain boards on an Optomux serial network; Dual network connectivity: RS-422/485 serial and 10/100 Mbps Ethernet; Optomux, Modbus/TCP, and OptoMMP protocol support; Can use Opto 22 PAC Project software for control, HMI, and OPC server
