3 Device Description
The safe F I/O module is intended for functional safety
automation technology, building technology and process technology, in order to
protect humans and machines according to Machinery Directive 2006/42/EC.
Connection to the safe PLC is established via the PROFINET IO fieldbus. The
F-I/O modules can be seamlessly integrated into the existing WAGO I/O
System 750.
Expensive, inflexible cabling is replaced by flexible, configurable safety functions,
thanks to secure PROFIsafe data transmission via the existing fieldbus system.
That makes it possible to optimize the F I/O module for different safety
applications.
The F I/O modules of the WAGO I/O System 750 can be used to implement
safety applications in accordance with the standards listed in Section
"Approvals" > "Applications".
The following actuators and sensors can be operated at the inputs of the 753-
661/000-004 F I/O module (see Section "Commissioning" > "Connection
Examples"):
• Potential-free emergency-off switches with contacts
• Safety interlock switches
• Operating mode selector switches
• Safe sensors
• Semiconductor outputs, compatible with type 1 inputs per IEC 61131-2
The 753-661/000-004 F I/O module has the following features:
• Four safety-oriented digital inputs I1 ... I4
• To clock outputs T1 and T2
• Diagnostics via LED indicators and fieldbus protocol (per IEC 61784-1)
• iPar server support for saving and restoring individual parameters
• Channel granular passivation of inputs
• Parameterizable channel and module properties
The inputs of the F I/O modules allow both single-channel and dual-channel
operation:
• Single-channel input function: connection of a sensor to a terminal
connection Ix
• Dual-channel input function: connection of a sensor to two terminal
connections Ix and Ix+1
The assignment of the connections is described in the "Connectors" section.
1 Functional safety evaluations were carried out by TÜV Rheinland.
