989EN

Key Features:

• 16 solid-state discrete I/O channels (any mix of inputs/outputs)
• High speed 1mS updates for all 16 channels
• 3-way isolation and surge suppression
• 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)
• Inputs detect level and change of state
• 8 configurable counter/timers
– 32-bit up/down pulse/event counters (with non-volatile memory)
– 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
• Self-test and auto-copy functions
• Operating Temperature Range: 989EN-4016:-40°C to +65°C (-40°F to +149°F);
989EN-4C16:0°C to +55°C (+32°F to +131°F).
