Industrial-grade models add a configurable integrator/totalizer plus superior accuracy and temperature performance compared to the economical commercial-grade version.

Input Ranges: ±5V, ±10V DC (selectable on each channel).

Ethernet Communication: Modbus TCP/IP, 10/100Base-T(X)

Power Requirement: 18 to 36V DC, 2.0W.

Approvals: CE, UL/cUL (industrial-grade units only) Zone 2, Class 1, Division 2, ABCD.

Performance Specifications

Accuracy
994EN-4016: Less than 0.05% of range.
994EN-4C16: Less than 0.10% of range.

Input Impedance: 4M ohms.

Operating Temperature and Humidity Ranges
994EN-4016: -40 to 70°C (-40 to 158°F).
994EN-4C16: 0 to 55°C (32 to 131°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.

Communication

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 128.1.1.100.

Port:
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 128.1.1.100 for initial configuration.

Environmental

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.

Electromagnetic Compatibility (EMC)

Immunity per European Norm EN50082-1. Emissions per European Norm EN50081-1.

Electrostatic Discharge (ESD) Immunity Per EN61000-4-2.
