The unit is not suited for environments with particular requirements on mechanical stability (e.g.
shock/vibration).
The unit is intended for indoor use only.
uObserve the operating conditions (Ò Technical data at www.ifm.com).
The accuracy and functionality of the unit can only be guaranteed within the specification.
If necessary, the user must provide appropriate digital input filters for the input signals.

4 Function
The device supports two different output behaviours:
1. It can output an input pulse stretched, shortened or delayed at the output.
2. The edge of the input signal can serve as a trigger to initiate a pulse at the output. The pulse
duration is set via a parameter.
For parameter setting and diagnostic purposes there is an IO-Link interface available. The following
options are available:
• Remote parameter setting: reading and changing the current parameter setting
• IO-Link parameter setting: IO Device Description (IODD) (Ò/8)
For diagnostic purposes, the input states and output states are available via the process data.
Due to the cycle time, the correctness of the process date displayed via IO-Link cannot be
guaranteed.
4.1 Application as an IO-Link device
4.1.1 General information
The unit has an IO-Link communication interface which requires an IO-Link capable module (IO-Link
master).
The IO-Link interface allows direct access to the process and diagnostic data and enables setting of
the parameters of the unit during operation.
You will find further information about IO-Link and all the necessary information about the required IO-
Link hardware and software at:
www.ifm.com/gb/io-link
4.1.2 Application
The use of the IO-Link interface in the application is not intended. It is mainly used for convenient
setting of the device.
4.1.3 IO Device Description (IODD)
You will find the IODDs necessary for the configuration of the IO-Link device and detailed information
about process data structure, diagnostic information and parameter addresses at:
www.ifm.com
4.2 Function diagrams
The output is defined as a normally open (no) or normally closed (nc) via the parameter [ou1] or [ou2].
4.2.1 Input configuration: pulse-controlled
The application of the switch-on and switch-off delay makes it possible to output input pulses
stretched, shortened or delayed at the output. The duration of the output pulse depends on the pulse
duration at the input.

After switching on, the device will not function properly until there is at least one rising edge at
the input.
4.2.2 Input configuration: edge-controlled
The edge of the input signal is the trigger for the output of pulses at the output. The duration of the
output pulse is always constant and is determined by the parameter [h.t1] or [h.t2]. The trigger can be
set to either the positive or negative edge.

5 Installation
uInstall the unit so that the M12 connection parts and the unit are protected from mechanical stress
such as shock and vibration.
uIf necessary, fix the unit with a clamp (use M4 screw or cable tie).
