972EN / 973EN
972EN / 973EN: Ethernet Analog Output Modules
• 4 or 6-channel DC current or voltage output
• Ethernet/IP, Modbus TCP/IP, i2o peer-to-peer messaging
These modules provide up to six channels of analog output. Multi-range outputs support a wide variety of industrial devices. They can drive displays and recorders, control drives, or send analog signals to other systems. High-resolution, low noise, D/A converters deliver high accuracy and reliability. 3-way isolation further improves system performance.
Output Ranges: Ranges selectable on channel to channel basis.
972EN: DC Current (user-selectable ranges): 0 to 1mA, 0 to 20mA, or 4 to 20mA.
973EN: DC Voltage (user-selectable ranges): 0 to 1V, 0 to 5V, or 0 to 10V DC.
Network Communication: EtherNet/IP or Modbus TCP/IP10/100Mbps with automatic data rate negotiation.
Power Requirement: 15 to 36V DC supply required. 4.6 Watts (972EN) or 2.3 Watts (973EN).
Approvals: CE/ATEX marked. UL, cUL listed, Class I; Div. 2; Groups A, B, C, D. EtherNet/IP, Modbus/TCP conformance tested.
Accuracy: Better than ±0.1% of span, typical. 1.6% for 0 to 1mA range. 0.8% for 0 to 1V range.
Digital to Analog Converter (D/A): 12-bit converter.
Current Output Compliance: 12V minimum, 13V typical.
Current Output Load Resistance Range: 0 to 555 ohms, typical.
Voltage Output Source Current: 0 to 10mA DC, maximum.
Ambient Operating Temperature:
972EN models -25 to 60°C (-13 to 140°F).
973EN models: -25 to 70°C (-13 to 158°F).
Ambient Storage Temperature: -40 to 85°C (-40 to 185°F).
Relative humidity: 5 to 95%, non-condensing.
Isolation: 1500V AC for 60 seconds or 250V AC continuous. 3-way isolation between I/O, network, and power. Outputs share a common.
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 126.96.36.199.
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 188.8.131.52 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.
