Safety
I/O Terminals Features
Safety Inputs
• Semiconductor output devices such light curtains can be connected as well as
contact output devices such as emergency stop switches.
• Faults in external wiring can be detected.
• Input delays (ON delays and OFF delays) can be set.
• Pairs of related local inputs can be set to Dual Channel Mode in order to be
compliant with the Category 4 standards.
When Dual Channel Mode is set, the input data patterns and the time discrepancy
between input signals can be evaluated.
Test Outputs
• 4 independent test outputs are available to use.
• A disconnected external indicator lamp can be detected. (Can be set for the T3
Terminal only.)
• Test outputs can be used as power supply terminals to devices such as sensors.
• Test outputs can be used as the standard output terminals for monitor outputs.
Safety Outputs
Semiconductor Outputs
• Pairs of related local outputs can be set to Dual Channel Mode in order to be
compliant with the Category 4 standards.
When Dual Channel Mode is set, the output data patterns can be evaluated.
• The rated output current is 0.5 A max. per output.
Relay Outputs
• Pairs of related output terminals can be set to Dual Channel Mode in order to be
compliant with the Category 4 standards.
When Dual Channel Mode is set, the output data patterns can be evaluated.
• The rated output current is 2 A max. per output.
• The safety relays can be replaced.
DeviceNet Safety Communications
As a Safety Slave, the DST1-series Safety I/O Terminals can perform safety I/O
communications with up to four connections.
DeviceNet Standard Communications
As a Standard Slave, the DST1-series Safety I/O Terminals can perform standard I/O
communications with one Standard Master with up to two connections.
System Startup and Error Recovery Support
• Error information can be checked by using the error log function or the indicators on
the front of the DST1-series Safety I/O Terminals.
• The DST1-series Safety I/O Terminal’s safety I/O data and internal status information
can be monitored from a Standard PLC by allocating the information in the standard
Master. In the same way, the information can be monitored from a safety PLC by
allocating the information in the Safety Master.
