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 terminal.
•
The safety relays can be replaced.
DeviceNet Safety Communications
As a Safety Slave, the Safety I/O Terminal can perform safety I/O communications with up to four connec-
tions.
DeviceNet Communications
As a Standard Slave, the Safety I/O Terminal 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
Safety I/O Terminal.
•
The Safety I/O Terminal's safety I/O data and internal status information can be monitored from a Stan-
dard 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.
Access Control with a Password
Safety I/O Terminal configuration data is protected by a password.
I/O Connector Connection/Disconnection
•
The I/O Connector can be connected and disconnected.
•
The I/O Connector is structured to prevent incorrect connection.
Cage Clamp Wiring
Cables can be wired without terminal screws.
Maintenance Functions
The Safety I/O Terminals are equipped with Maintenance Functions such as a contact operation counter, cu-
mulative ON time monitor, and operating time monitor.
