2 Safety instructions
The unit described is a subcomponent for integration into a system.
The system architect is responsible for the safety of the system.
The system architect undertakes to perform a risk assessment and to create documentation in
accordance with legal and normative requirements to be provided to the operator and user of
the system. This documentation must contain all necessary information and safety instructions
for the operator, the user and, if applicable, for any service personnel authorised by the
architect of the system.
Read this document before setting up the product and keep it during the entire service life.
The product must be suitable for the corresponding applications and environmental conditions
without any restrictions.
Only use the product for its intended purpose (Ò Intended use).
If the operating instructions or the technical data are not adhered to, personal injury and/or damage
to property may occur.
The manufacturer assumes no liability or warranty for any consequences caused by tampering with
the product or incorrect use by the operator.
Installation, electrical connection, set-up, operation and maintenance of the product must be
carried out by qualified personnel authorised by the machine operator.
Protect units and cables against damage.
Replace damaged units, otherwise the technical data and safety will be impaired.
The devices are intended for use with a 24 V DC safety extra-low voltage.
A wrong connection to voltage which is higher and/or not safely isolated may lead to damage or
conditions which are dangerous to life.
Use the supply module only with the matching circuit protection modules.
Do not mount the devices and do not actuate the contact levers while live.
After triggering a circuit protection module and before power on again, remove the cause of
triggering (short circuit or overload).
Check the devices for damage prior to installation. Defective devices must not be used.
Supply the devices with energy only after they have been properly installed.

4.1 Temperature factor / continuous current rating
The time-current characteristic curve depends on the ambient temperature. To determine the max.
permitted load current multiply the nominal device current by the temperature factor taking into
consideration the series connection.
Ambient temperature [°C] 0 10 23 40 50 60
Temperature factor 1 1 1 0.95 0.90 0.85
With series installation the nominal device current can be max. 80% or has to be overdimensioned
accordingly. With increased temperature the load current warning limit "warning limit typ. 0.8 x IN" is
reduced by the temperature factor.
4.2 Fail-safe element
The load circuits are additionally protected by the circuit protection modules that are equipped with a
fail-safe element (integrated fuse). The fail-safe element is adapted to the nominal current IN of the
respective circuit protection module and the respective wire cross-sections.

4.3 IO-Link
The load current warning threshold can be configured via the IO-Link interface to provide a
visual warning and a warning via IO-Link with a capacity utilisation between 50 and 100 %.
The IO-Link devices can also be used as stand-alone devices without IO-Link master.
Extended functions of the DF2101 supply module via IO-Link:
Min. / max. value generation of the measured current and voltage values for each channel over any
period of time
Averaging of the measured current and voltage values for each channel over any period of time
Permanent switching on of individual channels in order to ignore the cyclic data exchange (e.g. to
guarantee the voltage supply of important devices). The safety function remains active.
You will find the IODDs necessary for the configuration of an IO-Link device and detailed information
about parameter setting tools, process data structure, diagnostic information and parameter
addresses at www.ifm.com/gb/io-link.

To disconnect press the orange pusher using a suitable tool.
To open the push-in terminals IO-Link use a 2 mm wide micro screwdriver.
6.1 Supply, feedback and potential modules
In combination with GND potential modules (DF311x) the GND supply modules (DF310x) are used to
reduce wiring.
In order to avoid that subsequent modules are disconnected from the voltage supply when opening a
contact lever, a feedback module (DF3210) can be used to ensure that the respective modules are still
supplied with power.
A LOAD potential module (DF320x) is used to extend +24 V DC circuit protection outputs to other
connections.

7.1 DF21xx supply modules
The different operating states of the circuit protection modules are indicated by the status LED.
Status LED Operating status IO-Link communication
off Missing operating voltage no
green on Correct operation (Ò/10) yes
flashing Independent operation (Ò/10) no
orange on Uncritical error (Ò/10) yes
flashing no
red on Critical error (Ò/11) no
flashing System start (Ò/11) no
Tab.1: Status LED DF21xx supply modules
7.1.1 Correct operation
No fault occurred and there is connection to the IO-Link master.
7.1.2 Independent operation
No connection to the IO-Link master. If there is no connection to the IO-Link master when the
operating voltage has been applied, the supply module transfers the parameter data to the connected
circuit protection modules. The behaviour of the connected circuit protection modules is controlled via
the configuration of the supply module. Either the status of the circuit protection modules is kept
(FREEZE) or the circuit protection modules are switched off (UNFREEZE). If there is again connection
to the IO-Link master and no fault occurred, the device goes to the "correct operation" mode.
7.1.3 Uncritical error
No valid configuration data is available. The connected circuit protection modules remain switched off.
Cyclic data exchange is not possible, acyclic data exchange is conditionally possible. After the device
has received the valid configuration and parameter data, it quits this operating mode.

7.1.4 Critical error
During initialisation an error is found or a critical error occurs. Communication with the IO-Link master
is not possible. The connected circuit protection modules are and remain switched off.
uReboot the device.
7.1.5 System start
The supply module is initialised when the operating voltage is applied. During this time communication
with the IO-Link master is not possible.
7.2 DF22xx circuit protection modules
The different operating states of the circuit protection modules are indicated by the status LED.
Status LED Operating status Status of load output
off Missing operating voltage, error in initialisation or chan-
nel switched off via button
off
green on Channel switched on via button or IO-Link, no error on
green/orange flashing Load current limit reached on
orange on Overload or short circuit until disconnection on

7.3 Interrogation of module to confirm the set nominal current
Only for circuit protection modules with adjustable nominal current.
uPress the ON/OFF/reset button of the requested channel between 2 and 5 seconds.
wThe status LED of the selected channel flashes red once.
wThe status LED flashes orange to display the set nominal current. The LED flashes red once to
confirm completion of the cycle. The LED flashes orange, once or multiple times, in accordance
with nominal current setting in amperes (orange flashing once = 1 A; orange flashing twice = 2 A;
etc.).
wThe set nominal current is displayed five times. After 5 cycles the display changes to the current
operating status.
uTo interrupt/stop the interrogation cycle, and return to normal status indication mode, press the ON/
OFF/reset button of the requested channel at any time.
7.4 Setting of the nominal current
Only for circuit protection modules with adjustable nominal current.
uSet the nominal current via IO-Link using a corresponding parameter setting software.
