Subject to alterations without notice
Before commencing the installation
Disconnect the power supply of the device.
Ensure that devices cannot be accidentally restarted.
Verify isolation from the supply.
Earth and short circuit.
Cover or enclose neighboring units that are live.
Follow the engineering instructions of the device concerned.
Only suitably qualified personnel in accordance with
EN 50 110-1/-2 (VDE 0 105 Part 100) may work on this device/system.
Before installation and before touching the device ensure that you are free of electrostatic
charge.
The functional earth (FE) must be connected to the protective earth (PE) or to the potential equa-
lization. The system installer is responsible for implementing this connection.
Connecting cables and signal lines should be installed so that inductive or capacitive interfe-
rence do not impair the automation functions.
Install automation devices and related operating elements in such a way that they are well
protected against unintentional operation.
Suitable safety hardware and software measures should be implemented for the I/O interface so
that a line or wire breakage on the signal side does not result in undefined states in the automa-
tion devices.
Ensure a reliable electrical isolation of the low voltage for the 24 volt supply. Only use power
supply units complying with IEC 60 364-4-41 (VDE 0 100 Part 410) or HD 384.4.41 S2.
Deviations of the mains voltage from the rated value must not exceed the tolerance limits given
in the specifications, otherwise this may cause malfunction and dangerous operation.
Emergency stop devices complying with IEC/EN 60 204-1 must be effective in all operating
modes of the automation devices. Unlatching the emergency-stop devices must not cause
restart.
Devices that are designed for mounting in housings or control cabinets must only be operated
and controlled after they have been installed with the housing closed. Desktop or portable units
must only be operated and controlled in enclosed housings.
Measures should be taken to ensure the proper restart of programs interrupted after a voltage
dip or failure. This should not cause dangerous operating states even for a short time. If neces-
sary, emergency-stop devices should be implemented.
Wherever faults in the automation system may cause damage to persons or property, external
measures must be implemented to ensure a safe operating state in the event of a fault or
malfunction (for example, by means of separate limit switches, mechanical interlocks etc.).
The electrical installation must be carried out in accordance with the relevant regulations (e. g.
with regard to cable cross sections, fuses, PE).
All work relating to transport, installation, commissioning and maintenance must only be carried
out by qualified personnel. (IEC 60 364 and HD 384 and national work safety regulations).
All shrouds and doors must be kept closed during operation.

About this manual
D300717 1211 - BL20 I/O modules1-2
1.1 Documentation concept
This manual contains all information about the bus-independent I/O-modules for the modular TURCK
IP20 I/O system BL20.
The following chapters contain a short BL20 system description, exact descriptions of the I/O-modules’
functionality and their technical data as well as all general information concerning the whole system as
for example mounting/dismounting, labeling etc.
Furthermore, this manual contains a short description of the project planning and diagnostics software
for TURCK I/O-systems, the software I/O-ASSISTANT.
The bus-specific BL20-gateways, the connection to the different automation devices, the maximum
system extension as well as all other bus specific information are described in separate manuals
(www.turck.de).
