16-Channel Discrete Ethernet I/O Modules with Counter/Timers

Product Features

  • Self-test and auto-copy functions
  • 16-bit periodic timers for “last pulse”
  • Momentary/latch alarms (each counter)
  • Programmable debounce (0-65 seconds with 1mS resolution)
  • Programmable power-up conditions
  • Over-temperature, over-current, and over-voltage output protection
  • Ability to “read-back” output states
  • Watchdog timer output configurable for failsafe or hold-last-value operation
  • User-adjustable TCP Ports 1-99,999 for advanced network configuration
  • Web browser configuration
  • Automatic MDI/MDI-X negotiation
  • Inputs accept 2- or 3-wire sensors and active logic switches (dry contacts, prox, namur, 5-28V DC logic)

These modules provide an isolated Ethernet interface for any input/output mix of up to 16 discrete signals. Inputs sense status of dry contacts, switches, power supplies, and DC logic. Outputs control solid-state switching of lamps, horns, and other devices.
