96-Channel Ethernet Discrete I/O Modules ES2113

These EtherStax I/O blocks provide a high density solution to interface a large quantity of discrete I/O signals to your control system. With stackable aluminium housing, it creates a small footprint and stands up to harsh industrial environments.

The Acromag ES2113 provides 96-Channel Ethernet Discrete I/O modules.

Firstly, the active low input ranges 0 to 28V DC. Whilst, the output range is 0 to 28V DC (0.5A/ch) low side switches.

Secondly, communication is via Ethernet Communication 10/100Base-T(X) and 100Base-FX Modbus TCP/IP or UDP/IP protocol. Acromag i2o peer to peer technology is also available with Modbus. A power requirement of 18 to 36V DC (redundancy ready) is required. Certification approvals include: UL/cUL Class 1, Division 2, ABCD.

Features of the 96-Channel Ethernet Discrete I/O Modules ES2113 include:

  • Any mix inputs/outputs with 16 solid state discrete I/O channels
  • 96-Discrete I/O channels: Bi-directional channels support any input/output mix in a single unit.
  • Stacked mounting produces I/O in a very small footprint to save panel space.
  • Updates all 96 channels in 1mS.
  • Modbus TCP/IP or UDP/IP protocol: I/O functions as slave to host controller.
  • Peer-to-peer i2o communication: Inputs to one unit automatically update outputs on another over Ethernet link.
  • Event-driven updates transmit data in less than 5mS between peers with i2o.
  • 10 Modbus TCP/IP sockets/sessions: Multiple masters can talk to an EtherStax unit at the same time.
  • Self-test checks I/O operation: Test I/O channels from a web browser before wiring terminals to devices.
  • Selectable input “wetting” current: Internal current source eliminates pull-ups and improves dry contact interface.
  • Automatic change of state detection: Inputs detect quick momentary changes of state that occur between polling.
  • Internal or external port excitation: Selectable source on each 16-channel port simplifies wiring and adds flexibility for use with 5-28V DC logic.
  • Loop-back monitoring on all channels: Inputs confirm output states for increased system reliability.
  • Watchdog timers and failsafe outputs: Communication fault sends output to a pre-defined state or holds the last value.
  • Output open-load detection: Output fault detection is selectable on individual channels.
  • Thermal, current, voltage protection: I/O is protected from excessive levels to reduce downtime.
