989EN: Ethernet Discrete I/O Modules with Counter/Timers
• 16-channel discrete I/O
• 8 counter/timers
• Modbus TCP/IP communication
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.
Input: 0-28V DC, 31V DC maximum.
Output: 0-28V DC, 0.5A/ch max, 2A total.
Counter/Timers (Industrial-grade units): 8 up/down counters, 32-bit, 150Hz max. 8 timers, 16-bit, 1mS resolution.
Ethernet Communication: Modbus TCP/IP, 10/100Base-T(X)
Power Requirement: 18 to 36V DC (1.33 W)
Approvals (industrial-grade only): CE, UL/cUL Zone 2, Class 1, Division 2, ABCD.
989EN-4C16: Commercial (no counters)
Operating Temperature Range
989EN-4016, -40 to 65°C (-40 to 149°F).
989EN-4C16, 0 to 55°C (32 to 131°F).
Storage Temperature Range
989EN-4016, -40 to 85°C (-40 to 185°F).
989EN-4C16, 0 to 70°C (32 to 158°F).
Relative Humidity: 5 to 95%, non-condensing.
Isolation: 3-way isolation of I/O, power, network circuits.
Peak: 1500V AC, ANSI/ISA-82.01-1988.
Continuous: 250V AC, 354V DC.
Connector: Shielded RJ-45 sockets, 8-pin, 10BaseT/100BaseTX.
Wiring: Wired MDI. 9xxEN I/O modules do NOT support autocrossover. 900EN switch supports auto-crossover.
Protocol: EtherNet/IP or Modbus TCP/IP with web browser configuration. EtherNet/IP supports PCCC object for communication with legacy PLCs (e.g. SLC505).
IP Address: Default static IP address is 22.214.171.124.
Ethernet Modbus TCP/IP models (9xxEN-4xxx): Up to 10 Modbus TCP/IP sockets supported.
EtherNet/IP models (9xxEN-6xxx): Up to 10 EtherNet/IP sockets and 1 Modbus TCP/IP socket.
Data Rate: Auto-sensed, 10Mbps or 100Mbps.
Duplex: Auto-negotiated, full or half-duplex.
Compliance: IEEE 802.3, 802.3u, 802.3x, Ethernet II.
Configuration: Web page for configuration and control is built-in with Ethernet access via a standard web browser.
Communication Distance: Distance between network devices is generally limited to 100 meters using recommended cable. Distances may be extended using hubs and switches.
Address: IP address is automatically acquired at startup. Unit may be configured to retrieve this address from the network server using BOOTP (Bootstrap Protocol), or via DHCP (Dynamic Configuration Protocol). A static IP address is also user-programmable. A default toggle switch sets the static IP address to the default factory address of 126.96.36.199 for initial configuration.
Isolation: I/O channel, power, and network circuits are isolated from each other for common-mode voltages up to 250VAC, or 354V DC off DC power ground, on a continuous basis (will withstand 1500VAC dielectric strength test for one minute without breakdown). Complies with test requirements of ANSI/ISA-82.01- 1988 for voltage rating specified.
