981EN / 982EN / 983EN

Key Features:

• Configurable from standard web browser
• EtherNet/IP® or Ethernet Modbus TCP/IP communication with automatic
10/100Mbps data rate negotiation
• 12-channel stand-alone module has far lower start-up cost than multi-piece block I/O systems
• 0-35V DC solid-state logic interface can monitor or control a wide variety of devices
• i2o function enables direct input-to-output communication without a network controller
• Bidirectional I/O models facilitate loopback monitoring of the output state
• Socketed SIP resistors provide input and output 5.6K ohm pull-ups to the excitation supply
• Three selectable failsafe modes (off, last-state, or pre-defined) help prevent unsafe conditions
• Compact packaging with pluggable terminals saves space and simplifies wiring
• Wide operational temperature range: -25°C to +70°C (-13°F to +158°F).
• Approvals: CE/ATEX marked; UL, cUL listed, Class 1 Div 2 Groups A, B, C, D; EtherNet/IP, Modbus/TCP
