DST1-series 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 dis-
crepancy 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 out-
puts.
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 evalu-
ated.
• 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 evalu-
ated.
• The rated output current is 2 A max. per output.
• The safety relays can be replaced.
DeviceNet Safety Communications
As a Safety Slave, a DST1-series Safety I/O Terminal can perform safety I/O
communications on up to four connections (or up to two connections for the
DST1-XD0808SL-1).
DeviceNet Standard Communications
As a Standard Slave, the DST1-series Safety I/O Terminals can perform stan-
dard I/O communications with one Standard Master with up to two connec-
tions.
