Ethernet Discrete I/O Modules 981EN, 982EN, 983EN

These modules provide an isolated Ethernet network interface for 12 discrete input and or output channels. The outputs control industrial devices by direct on/off, high/low or open/close. Inputs senses the status of motors, pumps, valves and other equipment.

Whilst, the 983EN model features tandem I/O providing output level control and status verification in one unit.

The Acromag 981EN, 982EN and 983EN are Ethernet Discrete I/O Modules.

Firstly, they feature 12-channel discrete input and/or output to provide open/close control of various industrial devices. Along with Ethernet/IP or Modbus TCP/IP. Plus, i20 peer to peer communication is available in Modbus versions.

981EN: 12 Input Channels

982EN: 12 Output Channels

983EN: 12 Input/Output Channels

Typically applications for these modules is to sense the status of motors, pumps, valves and other equipment.

Secondly, the input and output range are 0 to 35V DC. They also require a 15 to 36V DC / 2 Watts Power Supply. Certification approvals for the product include: CE/ATEX marked; UL; cUL listed Class I: Div 2; Groups A, B, C,D; EtherNet/IP, Modbus/TCP Conformance Tested.

Features of the Ethernet Discrete I/O Modules 981EN, 982EN, 983EN include:

  • Standard web browser configurable 12 channel stand alone module
  • Lower start up cost than a multi piece block I/O system
  • 0-35V DC solid state logic interface to control or monitor a variety of devices
  • Bidirectional I/O modules facilitate loopback monitoring of output state
  • As well as socketed SIP resistors provide input and output 5.6K ohm pull ups to excitation supply
  • Three selectable failsafe modes (off, last-state or predefined) prevent unsafe conditions
