The DST1-ID12SL-1 supports 12 safety inputs.
The DST1-MD16SL-1 supports 8 safety inputs.
The DST1-MRD08SL-1 supports 4 safety inputs.
The DST1-XD0808SL-1 supports 8 safety inputs.
Diagnoses internal circuits and external devices and wiring using test
pulses.
The input time constant can be set from 0 to 126 ms in units of 6 ms. This
function can be used to reduce the effects of chattering and external
noise.
Dual channel evaluation can be used to evaluate the discrepancy time
between two associated local input data items or input signals.
Four independent test outputs are supported. Test outputs are used in
combination with safety inputs. Depending on the settings, they can also
be used as signal output terminals.
Broken wires can be detected for terminal T3.
When an overcurrent is detected, the output is turned OFF to protect the
circuit.
The DST1-MD16SL-1 supports 8 safety outputs.
The DST1-MRD08SL-1 supports 4 safety outputs.
The DST1-XD0808SL-1 supports 8 safety outputs.
Diagnoses internal circuits and external devices and wiring according to
test pulses.
When an overcurrent is detected, the output is turned OFF to protect the
circuit.
When an error occurs at one of two associated local outputs, the dual
channel evaluation sets the two outputs to the safe state without relying on
a user program.
DST1-series Terminals can be operated as DeviceNet Safety Slaves. Not
only specified I/O areas, but also internal status information can be
assigned in Safety Masters.
DST1-series Terminals can be operated as Standard Slaves. Not only
specified I/O areas, but also internal status information can be assigned in
Standard Masters.
Internal status information can be read by using a service for explicit mes-
sages.
The baud rate is automatically set to the baud rate of the network.
Internally saves information on errors that are detected.
Internal status information and I/O data can be read using the Network
Configurator.
