2900312 PHOENIX

Phoenix Contact offers analog output modules across several key product families, including the Inline modular I/O series, Axioline F fast I/O systems, and Axioline E field-level IP67 systems. These modules accept digital values transmitted across fieldbus or Ethernet networks—such as PROFINET, EtherNet/IP, Modbus TCP, or PROFIBUS—and precisely convert them into standard analog output signals. Built with high-precision digital-to-analog converters, integrated channel-to-channel isolation, and comprehensive onboard diagnostic functions, these modules ensure reliable control under harsh electrical conditions. The modular design enables easy snap-on mounting on standard DIN rails, simplifying system extension, wiring, and maintenance in both centralized control cabinets and decentralized field locations.

• Resolution: High-resolution digital-to-analog conversion, typically 12-bit to 16-bit resolution depending on the specific module series.

• Channel Density: Available in flexible configurations, including 2-channel, 4-channel, and 8-channel versions per module.

• Conversion Time and Response Rate: Fast update times starting under 1 millisecond per channel for high-speed dynamic control applications.

• Electrical Isolation: Galvanic isolation between channels, backplane bus, and supply power, typically rated up to 500 V AC or 1.5 kV AC dielectric withstand strength.

• Load Impedance: Voltage output load resistance greater than 2 kOhms; current output load resistance up to 500 Ohms or 750 Ohms.

• Supply Voltage: Nominal operating voltage of 24 V DC with an acceptable operating range from 19.2 V DC to 30 V DC.

• Operating Temperature: Extended industrial operating temperature range from -25°C to +60°C for standard cabinet modules, and up to +70°C for extended temperature variants.

• Connection Technology: Push-in direct plug connection or screw terminal options accommodating wire cross-sections from 0.2 to 1.5 square millimeters.

• System Bus Protocol Support: Seamless integration via coupler modules into PROFINET, EtherNet/IP, Modbus TCP, EtherCAT, and PROFIBUS DP networks.

Product Advantages

A key advantage of Phoenix Contact analog output modules is Push-in connection technology, which allows fast, tool-free wiring, significantly reducing assembly time and ensuring vibration-proof connections.

High noise immunity and advanced galvanic channel isolation protect sensitive control electronics from ground loops, surge spikes, and electromagnetic interference commonly present in heavy industrial facilities.

Integrated channel diagnostics continuously monitor output short circuits, open wire loops, and supply voltage errors, transmitting real-time fault statuses to the main controller to minimize operational downtime.

The compact enclosure design maximizes space utilization inside control cabinets, allowing system builders to achieve high I/O channel density within a small footprint.

Hot-swappable module capabilities on select series allow maintenance personnel to replace active modules without interrupting backplane communication or shutting down the broader automation network.

Important Considerations and Precautions

Installers must ensure that field signal lines use shielded twisted-pair cables, grounding the shield properly at a single point to prevent high-frequency noise from inducing errors into analog signals.

Always verify that the output configuration mode (voltage or current) set in the control software matches the physical wiring connected to the terminal points to prevent damaging connected field devices.

Ensure total loop load resistance for current output channels does not exceed the maximum specified impedance rating to maintain linear current output accuracy.

Adhere strictly to the recommended cabinet ventilation clearances and power supply line fusing to prevent overheating and overvoltage damage to internal conversion circuits.

Disconnect field power before wiring or performing maintenance on terminal blocks unless the specific module series explicitly supports live hot-swapping.

Product Applications

Phoenix Contact analog output modules are deployed extensively across automated processing, manufacturing, and infrastructure sectors.

• Process Valve and Actuator Control: Sending continuous 4 to 20 mA positioning signals to modulating control valves, dampers, and proportional pneumatic positioners in chemical and water treatment plants.

• Variable Frequency Drive Speed Control: Providing 0 to 10 V or 4 to 20 mA speed reference signals to VFDs and servo drives for precise motor speed adjustment in conveyor systems and pumps.

• Heating and Thermal Regulation: Regulating solid-state relays, power controllers, and industrial furnace heating elements to maintain tight temperature control profiles.

• Factory Automation and OEM Machinery: Interfacing with secondary controllers, analog displays, chart recorders, and signal conditioners in customized automated assembly machinery.

• Building Automation and HVAC: Controlling air damper actuators, variable air volume (VAV) systems, and chilled water valve positioners in large commercial HVAC control systems.
