Presentation
TSX PAY 262 safety module integrated in the Modicon Premium PLC combines :
v
the simplicity of use of Preventa safety module
v
the high performance of PLC diagnostics
in addition to the advantages of a standard PLC (extended choice of I/O, simplicity
of setup, flexibility for hardware and software developments, etc).
TSX PAY 262 safety module incorporate in a single module, a Preventa (XPS)
hard-wired safety block and an electronic data acquisition unit for complete
diagnostics of input contacts and the state of outputs in the safety system.
TSX PAY 262 safety module is used to safely interrupt one or more Emergency stop or
safety stop control circuits according to the standards IEC/EN 60204-1 and
EN/ISO 13850.
The proven safety of hard-wired technology and the performance of Premium PLCs
make the TSX PAY 262 module the optimum solution for creating machines which
are more available, safer, more compact and lower in cost.
Solution for applications requiring safety systems and high-performance
diagnostics
The solution “integrated safety module” enables complete diagnostics on the entire
safety system. This diagnostics quickly locates the faulty contact, pushbutton cables,
or limit switch, without additional contacts on the inputs and without any additional
wiring.
TSX PAY 262 safety module has its own power supplies and operate independently
of the PLC processor.
TSX PAY 262 module is suitable for Emergency stop and limit switch monitoring
applications, demanding a level of safety up to category 4 according to standard
EN 954-1/ISO 13849-1 (parts of control systems relating to safety).
Functions
TSX PAY 262 module offers the following functions:
b
Monitoring of 1 to 12 double or single pushbutton contacts, Emergency stop and
limit switches for safety guards for an Emergency stop or immediate stop safety
system (Emergency stop category 0 according to standard EN/ISO 13850).
b
Hard-wired safety block identical to Preventa XPS safety modules:
v
2
N/O (normally open) safety outputs,
v
12
double contact inputs.
b
Safety block independent of the Premium PLC processor: the PLC does not
operate on the safety module.
b
28
LEDs on the module display block: for complete diagnostics of the safety
system.
b
Electronic data acquisition units for complete diagnostics of the safety system:
v
read the status of the 24 inputs (image of the status of the 12 pushbuttons or limit
switches)
v
read the enable input,
v
read the feedback loop,
v
read the safety outputs control,
v
monitor the external power supply of the module.
This electronic data acquisition is designed so that the safety function is not
compromised by any failure. If the safety system uses more sensors, it is possible to
connect several TSX PAY 262 modules.
