Product Description

The DN4218 is a stand-alone power supply for single phase mains systems, which provides a stabilized and galvanically separated PELV/ES1 output voltage at 4 outputs. The negative potential of the outputs is permanently connected to PE within the unit. The housing is rated as IP65 and IP67 according IEC60529 and provides protection against electrical, mechanical and fire hazards. The outputs fulfill the requirements for a limited power source according to NEC Class2. The device is equipped with an IO-Link Interface V1.1 to parameterize and access data.

Intended Use

This indoor use device is intended for commercial use, such as in industrial control, process control, monitoring, measurement or the like. Do not use this device in equipment, where malfunctioning may cause severe personal injury or threaten human life, without additional appropriate safety devices, that are suited for the end-application. If used in a manner outside of its specification, the protection provided by the device may be impaired.

Installation Instructions

• Install the device with the terminals on the bottom of the device. Other mounting orientations require a reduction in output current.
• When installing watch out for the risk of injury from sharp edges and assure that when installed any sharp edges on the back cannot be accessed and cannot cause injury.
• Use 4 screws ( 2 on top and 2 on bottom mounting holes) suitable for the underground and a strength comparable to M4 or UNC 8-32 screws.
• The device is designed for pollution degree 3 areas in controlled environments.
• The enclosure of the device provides a degree of ingress protection of IP65 and IP67 when installed with all mating connectors firmly connected. Assure that during installation no moisture or dirt gets into the connections. Operation in areas where moisture
• or condensation can be expected is possible.
• The isolation of the device is designed to withstand impulse voltages of overvoltage category III according to IEC 60664-1.
• The device is designed as “Class of Protection I” equipment according to IEC 61140. Do not use without a proper PE (Protective Earth) connection.
• The device is suitable to be supplied from TN, TT or IT mains networks. The voltage between the input terminals and the PE potential must not exceed 264Vac.
• The device is designed for convection cooling without a fan. Do not obstruct airflow.
• The device is designed for altitudes up to 5000m (16400ft). Above 2000m (6560ft) a reduction in output current and overvoltage category is required.
• Keep the following minimum installation clearances: 30mm on top and bottom, 10mm on the front, the left and the right side.
• The device is designed, tested and approved for branch circuits up to 20A (UL) and 32A (IEC) without additional protection device. If an external fuse is utilized, do not use circuit breakers smaller than 6A B- or C-characteristic to avoid a nuisance tripping of
• the circuit breaker. For DC supply voltages above 150Vdc an external circuit breaker (rated 6A with B- or C-characteristic) is required.
• Make sure that you only use plugs and cables rated for the device output current and the required temperature range. Follow all local and national codes for installation.
• Do not connect outputs or devices in parallel for higher output currents.
• Do not connect the negative potential of any output to PE.
• The maximum permissible ambient air temperature is +70°C (+158°F). The operational temperature is the same as the ambient or ambient air temperature and is defined 2cm below the device.

WARNING: Risk of fire or electric shock. Cleaning only with a damp cloth.

Functional Description

The output is electronically protected against no-load, overload and short circuit and can supply any kind of loads, including inductive and capacitive loads. If capacitors with a capacitance >20mF are connected to one output, this output might switch off after turning the unit or the output on or connecting the load. Do not apply return voltages from the load to the output terminals higher than 35V. The green Status LED reports an output above 90% of the adjusted voltage of a running device and no output tripped due to overcurrent or overtemperature. The device has an internal overtemperature protection. If the temperature is too high the unit shuts down and starts automatically again after cooling off. Each output will get the same state as before the shutdown. In case of an internal defect, a redundant circuit limits the maximum output voltage to 32.5V. The unit shuts down and automatically attempts to restart. IO-Link gives access to internally measured parameters and can be used to change settings. For IODD files and additional descriptions please visit documentation.ifm.com. LED bar graph and pushbuttons: The LED bar normally displays the actual output power as percentage value. 100% equals an output power of 300W. LEDs up to and including 100% are green, the LEDs above 100% are orange. With the up and down button you can see the actual power per channel (orange LED indicates the currently selected channel). If you press the “Set Mode” button for 3 seconds all LEDs light up briefly and one LED stays on, showing the actual output voltage. With pressing the up or down button you can change the set voltage to the values indicated by the green LED. The voltage is set immediately and the value stored until the next change. If no button is pressed for 15s unit returns to the normal state the LED bar will return to show the output power.

Mating connectors

• Use a 3 Pin 7/8” female plug to connect to the input voltage connector (X1). Pin assignment for (X1): Pin 2 for L, Pin 3 for N, The Pin with the PE symbol for PE.
• Use a standard M12 A-coded 5 pin female plug for the IO Link.
• Use standard M12 A coded male plugs for the output voltage connectors (X3, X4).
• Pin assignment: Pin 1 for plus out (1,3); Pin 3 for minus out (1,3);
• Pin4 for plus out (2,4); Pin 2 for minus out (2,4); Pin5 for FE (functional earth).
